+## Dockerを使ってローカル環境でWebサイトを動かす
+
+ローカル環境で本ページを動かすのに推奨される方法は、静的サイトジェネレータの[Hugo](https://gohugo.io)を動かすのに特化した[Docker](https://docker.com)イメージを使うことです。
+
+> Windows上で環境を作る場合は[Chocolatey](https://chocolatey.org)を使ってインストール可能な追加のツールが必要になります。 `choco install make`
+
+> Dockerを使わずに環境を構築したい場合は、[Hugoをローカル環境で動かす](#hugoをローカル環境で動かす)をご覧ください。
+
+既に[Dockerが動いている環境](https://www.docker.com/get-started)であれば、以下のコマンドを使って`kubernetes-hugo`イメージをローカルでビルドします:
+
+```bash
+make docker-image
+```
+
+イメージが作成されたら、以下のコマンドを使ってWebサイトをローカル上で動かすことができます:
+
+```bash
+make docker-serve
+```
+
+お使いのブラウザにて http://localhost:1313 にアクセスすることでWebサイトが開きます。リポジトリ内のソースファイルに変更を加えると、HugoがWebサイトの内容を更新してブラウザに反映します。
+
+## Hugoをローカル環境で動かす
+
+Hugoのインストール方法については[Hugoの公式ドキュメント](https://gohugo.io/getting-started/installing/)をご覧ください。このとき、[`netlify.toml`](netlify.toml#L9)ファイルに記述されている`HUGO_VERSION`と同じバージョンをインストールするようにしてください。

 Hugoがインストールできたら、以下のコマンドを使ってWebサイトをローカル上で動かすことができます:

 ```bash
-git clone https://github.com/kubernetes/website.git
-cd website
-git submodule update --init --recursive --depth 1
+make serve
 ```

-**注意:** Kubernetesのウェブサイトでは[DocsyというHugoのテーマ](https://github.com/google/docsy#readme)を使用しています。リポジトリを更新していない場合、 `website/themes/docsy`ディレクトリは空です。 このサイトはテーマのローカルコピーなしでは構築できません。
+これで、Hugoのサーバーが1313番ポートを使って開始します。 お使いのブラウザにて http://localhost:1313 にアクセスしてください。リポジトリ内のソースファイルに変更を加えると、HugoがWebサイトの内容を更新してブラウザに反映します。

-テーマをアップデートするには以下のコマンドを実行します:
+## コミュニティ内での議論、貢献、サポートなどについて

-## Running the website locally using Hugo
-
-See the [official Hugo documentation](https://gohugo.io/getting-started/installing/) for Hugo installation instructions. Make sure to install the Hugo extended version specified by the `HUGO_VERSION` environment variable in the [`netlify.toml`](netlify.toml#L10) file.
-->
-## 在本地使用 Hugo 来运行网站
-
-请参考 [Hugo 的官方文档](https://gohugo.io/getting-started/installing/)了解 Hugo 的安装指令。
-请确保安装的是 [`netlify.toml`](netlify.toml#L10) 文件中环境变量 `HUGO_VERSION` 所指定的
-Hugo 扩展版本。
-
-<!--
-Before building the site, clone the Kubernetes website repository:
-->
-在构造网站之前，先克隆 Kubernetes website 仓库：
-
-```bash
-git clone https://github.com/kubernetes/website.git
-cd website
-git submodule update --init --recursive
-```
-
-<!--
-**Note:**  The Kubernetes website deploys the [Docsy Hugo theme](https://github.com/google/docsy#readme).
-If you have not updated your website repository, the `website/themes/docsy` directory is empty.
-The site cannot build without a local copy of the theme.
-
-Update the website theme:
-->
-**注意：** Kubernetes 网站要部署 [Docsy Hugo 主题](https://github.com/google/docsy#readme).
-如果你还没有更新你本地的 website 仓库，目录 `website/themes/docsy`
-会是空目录。
-在本地没有主题副本的情况下，网站无法正常构造。
-
-使用下面的命令更新网站主题：
-
-```bash
-git submodule update --init --recursive --depth 1
-```
-
-<!--
-To build and test the site locally, run:
-->
-若要在本地构造和测试网站，请运行：
-
-```bash
-hugo server --buildFuture
-```
-
-<!--
-This will start the local Hugo server on port 1313. Open up your browser to http://localhost:1313 to view the website. As you make changes to the source files, Hugo updates the website and forces a browser refresh.
-->
-上述命令会在端口 1313 上启动本地 Hugo 服务器。
-启动浏览器，打开 http://localhost:1313 来查看网站。
-当你对源文件作出修改时，Hugo 会更新网站并强制浏览器执行刷新操作。

 This repository contains the assets required to build the [Kubernetes website and documentation](https://kubernetes.io/). We're glad that you want to contribute!

-# Using this repository
-
-You can run the website locally using Hugo, or you can run it in a container runtime. We strongly recommend using the container runtime, as it gives deployment consistency with the live website.
-
-## Prerequisites
-
-To use this repository, you need the following installed locally:
-
- [yarn](https://yarnpkg.com/)
- [npm](https://www.npmjs.com/)
- [Go](https://golang.org/)
- [Hugo](https://gohugo.io/)
- A container runtime, like [Docker](https://www.docker.com/).
-
-Before you start, install the dependencies. Clone the repository and navigate to the directory:
-
-```
-git clone https://github.com/kubernetes/website.git
-cd website
-```
-
-The Kubernetes website uses the [Docsy Hugo theme](https://github.com/google/docsy#readme). Even if you plan to run the website in a container, we strongly recommend pulling in the submodule and other development dependencies by running the following:
-
-```
-# install dependencies
-yarn
-
-# pull in the Docsy submodule
-git submodule update --init --recursive --depth 1
-```
-
-## Running the website using a container
-
-To build the site in a container, run the following to build the container image and run it:
-
-```
-make container-image
-make container-serve
-```
-
-Open up your browser to http://localhost:1313 to view the website. As you make changes to the source files, Hugo updates the website and forces a browser refresh.
-
 ## Running the website locally using Hugo

-Make sure to install the Hugo extended version specified by the `HUGO_VERSION` environment variable in the [`netlify.toml`](netlify.toml#L10) file.
+See the [official Hugo documentation](https://gohugo.io/getting-started/installing/) for Hugo installation instructions. Make sure to install the Hugo extended version specified by the `HUGO_VERSION` environment variable in the [`netlify.toml`](netlify.toml#L10) file.

-To build and test the site locally, run:
+To run the website locally when you have Hugo installed:

 ```bash
-make serve
+git clone https://github.com/kubernetes/website.git
+cd website
+hugo server --buildFuture
 ```

 This will start the local Hugo server on port 1313. Open up your browser to http://localhost:1313 to view the website. As you make changes to the source files, Hugo updates the website and forces a browser refresh.

-### Troubleshooting macOS for too many open files
-
-If you run `make serve` on macOS and receive the following error:
-
-```
-ERROR 2020/08/01 19:09:18 Error: listen tcp 127.0.0.1:1313: socket: too many open files
-make: *** [serve] Error 1
-```
-
-Try checking the current limit for open files:
-
-`launchctl limit maxfiles`
-
-Then run the following commands:
-
-```
-#!/bin/sh

-
-sudo mv limit.maxfiles.plist /Library/LaunchDaemons
-sudo mv limit.maxproc.plist /Library/LaunchDaemons
-
-sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist
-sudo chown root:wheel /Library/LaunchDaemons/limit.maxproc.plist
-
-sudo launchctl load -w /Library/LaunchDaemons/limit.maxfiles.plist

 The benefits of thinking in terms of modular containers are enormous, in particular, modular containers provide the following:

 Building an application from modular containers means thinking about symbiotic groups of containers that cooperate to provide a service, not one container per service. &nbsp;In Kubernetes, the embodiment of this modular container service is a Pod. &nbsp;A Pod is a group of containers that share resources like file systems, kernel namespaces and an IP address. &nbsp;The Pod is the atomic unit of scheduling in a Kubernetes cluster, precisely because the symbiotic nature of the containers in the Pod require that they be co-scheduled onto the same machine, and the only way to reliably achieve this is by making container groups atomic scheduling units.

 In mid 2014 we looked at the challenges enterprises are facing in the context of digitization, where traditional enterprises experience that more and more competitors from the IT sector are pushing into the core of their markets. A big part of Fujitsu’s customers are such traditional businesses, so we considered how we could help them and came up with three basic principles:

- Decouple applications from infrastructure - Focus on where the value for the customer is: the application.
- Decompose applications - Build applications from smaller, loosely coupled parts. Enable reconfiguration of those parts depending on the needs of the business. Also encourage innovation by low-cost experiments.
- Automate everything - Fight the increasing complexity of the first two points by introducing a high degree of automation.

 We found that Linux containers themselves cover the first point and touch the second. But at this time there was little support for creating distributed applications and running them managed automatically. We found Kubernetes as the missing piece.
 **Not a free lunch**  

 The general approach of Kubernetes in managing containerized workload is convincing, but as we looked at it with the eyes of customers, we realized that it’s not a free lunch. Many &nbsp;customers are medium-sized companies whose core business is often bound to strict data protection regulations. The top three requirements we identified are:

- On-premise deployments (with the option for hybrid scenarios)
- Efficient operations as part of a (much) bigger IT infrastructure
- Enterprise-grade support, potentially on global scale

-**Author:** Zach Corleissen, Cloud Native Computing Foundation
-
-*Editor's note: Zach is one of the chairs for the Kubernetes documentation special interest group (SIG Docs).*
-
-I'm pleased to announce that the [Kubernetes website](https://kubernetes.io) now features the [Docsy Hugo theme](https://docsy.dev).
-
-The Docsy theme improves the site's organization and navigability, and opens a path to improved API references. After over 4 years with few meaningful UX improvements, Docsy implements some best practices for technical content. The theme makes the Kubernetes site easier to read and makes individual pages easier to navigate. It gives the site a much-needed facelift.
-
-For example: adding a right-hand rail for navigating topics on the page. No more scrolling up to navigate!
-
-The theme opens a path for future improvements to the website. The Docsy functionality I'm most excited about is the theme's [`swaggerui` shortcode](https://www.docsy.dev/docs/adding-content/shortcodes/#swaggerui), which provides native support for generating API references from an OpenAPI spec. The CNCF is partnering with [Google Season of Docs](https://developers.google.com/season-of-docs) (GSoD) for staffing to make better API references a reality in Q4 this year. We're hopeful to be chosen, and we're looking forward to Google's list of announced projects on August 16th. Better API references have been a personal goal since I first started working with SIG Docs in 2017. It's exciting to see the goal within reach. 
-
-One of SIG Docs' tech leads, [Karen Bradshaw](https://github.com/kbhawkey) did a lot of heavy lifting to fix a wide range of site compatibility issues, including a fix to the last of our [legacy pieces](https://github.com/kubernetes/website/pull/21359) when we [migrated from Jekyll to Hugo](2018-05-05-hugo-migration/) in 2018. Our other tech leads, [Tim Bannister](https://github.com/sftim) and [Taylor Dolezal](https://github.com/onlydole) provided extensive reviews.
-
-Thanks also to [Björn-Erik Pedersen](https://bep.is/), who provided invaluable advice about how to navigate a Hugo upgrade beyond [version 0.60.0](https://gohugo.io/news/0.60.0-relnotes/).
-
-The CNCF contracted with [Gearbox](https://gearboxbuilt.com/) in Victoria, BC to apply the theme to the site. Thanks to Aidan, Troy, and the rest of the team for all their work!

-Maintaining Kubestack, an open-source [Terraform GitOps Framework](https://www.kubestack.com/lp/terraform-gitops-framework) for Kubernetes, I unsurprisingly spend a lot of time working with Terraform and Kubernetes. Kubestack provisions managed Kubernetes services like AKS, EKS and GKE using Terraform but also integrates cluster services from Kustomize bases into the GitOps workflow. Think of cluster services as everything that's required on your Kubernetes cluster, before you can deploy application workloads.

I took this as an opportunity to give an overview of how Terraform can be used with Kubernetes today and what to be aware of.
-
-In this post I will however focus only on using Terraform to provision Kubernetes API resources, not Kubernetes clusters.
-
-[Terraform](https://www.terraform.io/intro/index.html) is a popular infrastructure as code solution, so I will only introduce it very briefly here. In a nutshell, Terraform allows declaring a desired state for resources as code, and will determine and execute a plan to take the infrastructure from its current state, to the desired state.
-
-To be able to support different resources, Terraform requires providers that integrate the respective API. So, to create Kubernetes resources we need a Kubernetes provider. Here are our options:
-
-## Terraform `kubernetes` provider (official)
-
-First, the [official Kubernetes provider](https://github.com/hashicorp/terraform-provider-kubernetes). This provider is undoubtedly the most mature of the three. However, it comes with a big caveat that's probably the main reason why using Terraform to maintain Kubernetes resources is not a popular choice.
-
-Terraform requires a schema for each resource and this means the maintainers have to translate the schema of each Kubernetes resource into a Terraform schema. This is a lot of effort and was the reason why for a long time the supported resources where pretty limited. While this has improved over time, still not everything is supported. And especially [custom resources](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/) are not possible to support this way.
-
-This schema translation also results in some edge cases to be aware of. For example, `metadata` in the Terraform schema is a list of maps. Which means you have to refer to the `metadata.name` of a Kubernetes resource like this in Terraform: `kubernetes_secret.example.metadata.0.name`.
-
-On the plus side however, having a Terraform schema means full integration between Kubernetes and other Terraform resources. Like for [example](https://github.com/kbst/terraform-kubestack/blob/e5caa6d20926d546a045144ebe79c7cc8c0b4c8a/aws/_modules/eks/ingress.tf#L37), using Terraform to create a Kubernetes service of type `LoadBalancer` and then use the returned ELB hostname in a Route53 record to configure DNS.
-
-The biggest benefit when using Terraform to maintain Kubernetes resources is integration into the Terraform plan/apply life-cycle. So you can review planned changes before applying them. Also, using `kubectl`, purging of resources from the cluster is not trivial without manual intervention. Terraform does this reliably.
-
-## Terraform `kubernetes-alpha` provider
-
-Second, the new [alpha Kubernetes provider](https://github.com/hashicorp/terraform-provider-kubernetes-alpha). As a response to the limitations of the current Kubernetes provider the Hashicorp team recently released an alpha version of a new provider.
-
-This provider uses dynamic resource types and server-side-apply to support all Kubernetes resources. I personally think this provider has the potential to be a game changer - even if [managing Kubernetes resources in HCL](https://github.com/hashicorp/terraform-provider-kubernetes-alpha#moving-from-yaml-to-hcl) may still not be for everyone. Maybe the Kustomize provider below will help with that.
-
-The only downside really is, that it's explicitly discouraged to use it for anything but testing. But the more people test it, the sooner it should be ready for prime time. So I encourage everyone to give it a try.
-
-## Terraform `kustomize` provider
-
-Last, we have the [`kustomize` provider](https://github.com/kbst/terraform-provider-kustomize). Kustomize provides a way to do customizations of Kubernetes resources using inheritance instead of templating. It is designed to output the result to `stdout`, from where you can apply the changes using `kubectl`. This approach means that `kubectl` edge cases like no purging or changes to immutable attributes still make full automation difficult.
-
-Kustomize is a popular way to handle customizations. But I was looking for a more reliable way to automate applying changes. Since this is exactly what Terraform is great at the Kustomize provider was born.
-
-Not going into too much detail here, but from Terraform's perspective, this provider treats every Kubernetes resource as a JSON string. This way it can handle any Kubernetes resource resulting from the Kustomize build. But it has the big disadvantage that Kubernetes resources can not easily be integrated with other Terraform resources. Remember the load balancer example from above.
-
-Under the hood, similarly to the new Kubernetes alpha provider, the Kustomize provider also uses the dynamic Kubernetes client and server-side-apply. Going forward, I plan to deprecate this part of the Kustomize provider that overlaps with the new Kubernetes provider and only keep the Kustomize integration.
-
-## Conclusion
-
-For teams that are already invested into Terraform, or teams that are looking for ways to replace `kubectl` in automation, Terraform's plan/apply life-cycle has always been a promising option to automate changes to Kubernetes resources. However, the limitations of the official Kubernetes provider resulted in this not seeing significant adoption.
-
-The new alpha provider removes the limitations and has the potential to make Terraform a prime option to automate changes to Kubernetes resources.
-
-Teams that have already adopted Kustomize, may find integrating Kustomize and Terraform using the Kustomize provider beneficial over `kubectl` because it avoids common edge cases. Even if in this set up, Terraform can only easily be used to plan and apply the changes, not to adapt the Kubernetes resources. In the future, this issue may be resolved by combining the Kustomize provider with the new Kubernetes provider.
-
-If you have any questions regarding these three options, feel free to reach out to me on the Kubernetes Slack in either the [#kubestack](https://app.slack.com/client/T09NY5SBT/CMBCT7XRQ) or the [#kustomize](https://app.slack.com/client/T09NY5SBT/C9A5ALABG) channel. If you happen to give any of the providers a try and encounter a problem, please file a GitHub issue to help the maintainers fix it.

-title: "SIG-Windows Spotlight"
-date: 2020-06-30
-slug: sig-windows-spotlight-2020
---
-
-_This post tells the story of how Kubernetes contributors work together to provide a container orchestrator that works for both Linux and Windows._
-
-<img alt="Image of a computer with Kubernetes logo" width="30%" src="KubernetesComputer_transparent.png">
-
-Most people who are familiar with Kubernetes are probably used to associating it with Linux. The connection makes sense, since Kubernetes ran on Linux from its very beginning. However, many teams and organizations working on adopting Kubernetes need the ability to orchestrate containers on Windows. Since the release of Docker and rise to popularity of containers, there have been efforts both from the community and from Microsoft itself to make container technology as accessible in Windows systems as it is in Linux systems.
-
-Within the Kubernetes community, those who are passionate about making Kubernetes accessible to the Windows community can find a home in the Windows Special Interest Group. To learn more about SIG-Windows and the future of Kubernetes on Windows, I spoke to co-chairs [Mark Rossetti](https://github.com/marosset)  and [Michael Michael](https://github.com/michmike) about the SIG's goals and how others can contribute.
-
-## Intro to Windows Containers & Kubernetes
-
-Kubernetes is the most popular tool for orchestrating container workloads, so to understand the Windows Special Interest Group (SIG) within the Kubernetes project, it's important to first understand what we mean when we talk about running containers on Windows.
-
-***
-_"When looking at Windows support in Kubernetes," says SIG (Special Interest Group) Co-chairs Mark Rossetti and Michael Michael, "many start drawing comparisons to Linux containers. Although some of the comparisons that highlight limitations are fair, it is important to distinguish between operational limitations and differences between the Windows and Linux operating systems. Windows containers run the Windows operating system and Linux containers run Linux."_
-***
-
-In essence, any "container" is simply a process being run on its host operating system, with some key tooling in place to isolate that process and its dependencies from the rest of the environment. The goal is to make that running process safely isolated, while taking up minimal resources from the system to perform that isolation. On Linux, the tooling used to isolate processes to create "containers" commonly boils down to cgroups and namespaces (among a few others), which are themselves tools built in to the Linux Kernel.
-
-<img alt="A visual analogy using dogs to explain Linux cgroups and namespaces." width="40%" src="cgroupsNamespacesComboPic.png">
-
-#### _If dogs were processes: containerization would be like giving each dog their own resources like toys and food using cgroups, and isolating troublesome dogs using namespaces._
-
-
-Native Windows processes are processes that are or must be run on a Windows operating system. This makes them fundamentally different from a process running on a Linux operating system. Since Linux containers are Linux processes being isolated by the Linux kernel tools known as cgroups and namespaces, containerizing native Windows processes meant implementing similar isolation tools within the Windows kernel itself. Thus, "Windows Containers" and "Linux Containers" are fundamentally different technologies, even though they have the same goals (isolating processes) and in some ways work similarly (using kernel level containerization).
-
-So when it comes to running containers on Windows, there are actually two very important concepts to consider:
-
-* Native Windows processes running as native Windows Server style containers,
-* and traditional Linux containers running on a Linux Kernel, generally hosted on a lightweight Hyper-V Virtual Machine.
-
-You can learn more about Linux and Windows containers in this [tutorial](https://docs.microsoft.com/en-us/virtualization/windowscontainers/deploy-containers/linux-containers) from Microsoft.
-
-
-
-### Kubernetes on Windows
-
-Kubernetes was initially designed with Linux containers in mind and was itself designed to run on Linux systems. Because of that, much of the functionality of Kubernetes involves unique Linux functionality. The Linux-specific work is intentional--we all want Kubernetes to run optimally on Linux--but there is a growing demand for similar optimization for Windows servers. For cases where users need container orchestration on Windows, the Kubernetes contributor community of SIG-Windows has incorporated functionality for Windows-specific use cases.
-
-***
-_"A common question we get is, will I be able to have a Windows-only cluster. The answer is NO. Kubernetes control plane components will continue to be based on Linux, while SIG-Windows is concentrating on the experience of having Windows worker nodes in a Kubernetes cluster."_
-***
-
-Rather than separating out the concepts of "Windows Kubernetes," and "Linux Kubernetes," the community of SIG-Windows works toward adding functionality to the main Kubernetes project which allows it to handle use cases for Windows. These Windows capabilities mirror, and in some cases add unique functionality to, the Linux use cases Kubernetes has served since its release in 2014 (want to learn more history? Scroll through this [original design document](https://github.com/kubernetes/kubernetes/blob/e2b948dbfbba62b8cb681189377157deee93bb43/DESIGN.md).
-
-
-## What Does SIG-Windows Do?
-
-***
-_"SIG-Windows is really the center for all things Windows in Kubernetes,"_ SIG chairs Mark and Michael said, _"We mainly focus on the compute side of things, but really anything related to running Kubernetes on Windows is in scope for SIG-Windows."_
-***
-
-In order to best serve users, SIG-Windows works to make the Kubernetes user experience as consistent as possible for users of Windows and Linux. However some use cases simply only apply to one Operating System, and as such, the SIG-Windows group also works to create functionality that is unique to Windows-only workloads.
-
-Many SIGs, or "Special Interest Groups" within Kubernetes have a narrow focus, allowing members to dive deep on a certain facet of the technology. While specific expertise is welcome, those interested in SIG-Windows will find it to be a great community to build broad understanding across many focus areas of Kubernetes. "Members from our SIG interface with storage, network, testing, cluster-lifecycle and others groups in Kubernetes."
-
-### Who are SIG-Windows' Users?
-The best way to understand the technology a group makes, is often to understand who their customers or users are.
-
-
-
-#### "A majority of the users we've interacted with have business-critical infrastructure running on Windows developed over many years and can't move those workloads to Linux for various reasons (cost, time, compliance, etc)," the SIG chairs shared. "By transporting those workloads into Windows containers and running them in Kubernetes they are able to quickly modernize their infrastructure and help migrate it to the cloud."
-
-As anyone in the Kubernetes space can attest, companies around the world, in many different industries, see Kubernetes as their path to modernizing their infrastructure. Often this involves re-architecting or event totally re-inventing many of the ways they've been doing business. With the goal being to make their systems more scalable, more robust, and more ready for anything the future may bring. But not every application or workload can or should change the core operating system it runs on, so many teams need the ability to run containers at scale on Windows, or Linux, or both.
-
-"Sometimes the driver to Windows containers is a modernization effort and sometimes it’s because of expiring hardware warranties or end-of-support cycles for the current operating system. Our efforts in SIG-Windows enable Windows developers to take advantage of cloud native tools and Kubernetes to build and deploy distributed applications faster. That’s exciting! In essence, users can retain the benefits of application availability while decreasing costs."
-
-## Who are SIG-Windows?
-
-Who are these contributors working on enabling Windows workloads for Kubernetes? It could be you!
-
-Like with other Kubernetes SIGs, contributors to SIG-Windows can be anyone from independent hobbyists to professionals who work at many different companies. They come from many different parts of the world and bring to the table many different skill sets.
-
-<img alt="Image of several people chatting pleasantly" width="30%" src="PeopleDoodle_transparent.png">
-
-_"Like most other Kubernetes SIGs, we are a very welcome and open community," explained the SIG co-chairs Michael Michael and Mark Rosetti._
-
-
-### Becoming a contributor
-
-For anyone interested in getting started, the co-chairs added, "New contributors can view old community meetings on GitHub (we record every single meeting going back three years), read our documentation, attend new community meetings, ask questions in person or on Slack, and file some issues on Github. We also attend all KubeCon conferences and host 1-2 sessions, a contributor session, and meet-the-maintainer office hours."
-
-The co-chairs also shared a glimpse into what the path looks like to becoming a member of the SIG-Windows community:
-
-"We encourage new contributors to initially just join our community and listen, then start asking some questions and get educated on Windows in Kubernetes. As they feel comfortable, they could graduate to improving our documentation, file some bugs/issues, and eventually they can be a code contributor by fixing some bugs. If they have long-term and sustained substantial contributions to Windows, they could become a technical lead or a chair of SIG-Windows. You won't know if you love this area unless you get started :) To get started, [visit this getting-started page](https://github.com/kubernetes/community/tree/master/sig-windows). It's a one stop shop with links to everything related to SIG-Windows in Kubernetes."
-
-When asked if there were any useful skills for new contributors, the co-chairs said,
-
-"We are always looking for expertise in Go and Networking and Storage, along with a passion for Windows. Those are huge skills to have. However, we don’t require such skills, and we welcome any and all contributors, with varying skill sets. If you don’t know something, we will help you acquire it."
-
-You can get in touch with the folks at SIG-Windows in their [Slack channel](https://kubernetes.slack.com/archives/C0SJ4AFB7) or attend one of their regular meetings - currently 30min long on Tuesdays at 12:30PM EST! You can find links to their regular meetings as well as past meeting notes and recordings from the [SIG-Windows README](https://github.com/kubernetes/community/tree/master/sig-windows#readme) on GitHub.
-
-As a closing message from SIG-Windows:
-
-***
-#### _"We welcome you to get involved and join our community to share feedback and deployment stories, and contribute to code, docs, and improvements of any kind."_

-
-**Author**: Adam Glick (Google)
-
-Every time the Kubernetes release train stops at the station, we like to ask the release lead to take a moment to reflect on their experience. That takes the form of an interview on the weekly [Kubernetes Podcast from Google](https://kubernetespodcast.com/) that I co-host with [Craig Box](https://twitter.com/craigbox). If you're not familiar with the show, every week we summarise the new in the Cloud Native ecosystem, and have an insightful discussion with an interesting guest from the broader Kubernetes community.
-
-At the time of the 1.17 release in December, we [talked to release team lead Guinevere Saenger](https://kubernetespodcast.com/episode/083-kubernetes-1.17/). We have [shared](https://kubernetes.io/blog/2018/07/16/how-the-sausage-is-made-the-kubernetes-1.11-release-interview-from-the-kubernetes-podcast/) [the](https://kubernetes.io/blog/2019/05/13/cat-shirts-and-groundhog-day-the-kubernetes-1.14-release-interview/) [transcripts](https://kubernetes.io/blog/2019/12/06/when-youre-in-the-release-team-youre-family-the-kubernetes-1.16-release-interview/) of previous interviews on the Kubernetes blog, and we're very happy to share another today.
-
-Next week we will bring you up to date with the story of Kubernetes 1.18, as we gear up for the release of 1.19 next month. [Subscribe to the show](https://kubernetespodcast.com/subscribe/) wherever you get your podcasts to make sure you don't miss that chat!

-
-**ADAM GLICK: You have a nontraditional background for someone who works as a software engineer. Can you explain that background?**
-
-GUINEVERE SAENGER: My first career was as a [collaborative pianist](https://en.wikipedia.org/wiki/Collaborative_piano), which is an academic way of saying "piano accompanist". I was a classically trained pianist who spends most of her time onstage, accompanying other people and making them sound great.
-
-**ADAM GLICK: Is that the piano equivalent of pair-programming?**
-
-GUINEVERE SAENGER: No one has said it to me like that before, but all sorts of things are starting to make sense in my head right now. I think that's a really great way of putting it.
-
-**ADAM GLICK: That's a really interesting background, as someone who also has a background with music. What made you decide to get into software development?**
-
-GUINEVERE SAENGER: I found myself in a life situation where I needed more stable source of income, and teaching music, and performing for various gig opportunities, was really just not cutting it anymore. And I found myself to be working really, really hard with not much to show for it. I had a lot of friends who were software engineers. I live in Seattle. That's sort of a thing that happens to you when you live in Seattle — you get to know a bunch of software engineers, one way or the other.
-
-The ones I met were all lovely people, and they said, hey, I'm happy to show you how to program in Python. And so I did that for a bit, and then I heard about this program called [Ada Developers Academy](https://adadevelopersacademy.org/). That's a year long coding school, targeted at women and non-binary folks that are looking for a second career in tech. And so I applied for that.
-
-**CRAIG BOX: What can you tell us about that program?**
-
-GUINEVERE SAENGER: It's incredibly selective, for starters. It's really popular in Seattle and has gotten quite a good reputation. It took me three tries to get in. They do two classes a year, and so it was a while before I got my response saying 'congratulations, we are happy to welcome you into Cohort 6'. I think what sets Ada Developers Academy apart from other bootcamp style coding programs are three things, I think? The main important one is that if you get in, you pay no tuition. The entire program is funded by company sponsors.
-
-**CRAIG BOX: Right.**
-
-GUINEVERE SAENGER: The other thing that really convinced me is that five months of the 11-month program are an industry internship, which means you get both practical experience, mentorship, and potential job leads at the end of it.
-
-**CRAIG BOX: So very much like a condensed version of the University of Waterloo degree, where you do co-op terms.**
-
-GUINEVERE SAENGER: Interesting. I didn't know about that.
-
-**CRAIG BOX: Having lived in Waterloo for a while, I knew a lot of people who did that. But what would you say the advantages were of going through such a condensed schooling process in computer science?**
-
-GUINEVERE SAENGER: I'm not sure that the condensed process is necessarily an advantage. I think it's a necessity, though. People have to quit their jobs to go do this program. It's not an evening school type of thing.
-
-**CRAIG BOX: Right.**
-
-GUINEVERE SAENGER: And your internship is basically a full-time job when you do it. One thing that Ada was really, really good at is giving us practical experience that directly relates to the workplace. We learned how to use Git. We learned how to design websites using [Rails](https://rubyonrails.org/). And we also learned how to collaborate, how to pair-program. We had a weekly retrospective, so we sort of got a soft introduction to workflows at a real workplace. Adding to that, the internship, and I think the overall experience is a little bit more 'practical workplace oriented' and a little bit less academic.
-
-When you're done with it, you don't have to relearn how to be an adult in a working relationship with other people. You come with a set of previous skills. There are Ada graduates who have previously been campaign lawyers, and veterinarians, and nannies, cooks, all sorts of people. And it turns out these skills tend to translate, and they tend to matter.
-
-**ADAM GLICK: With your background in music, what do you think that that allows you to bring to software development that could be missing from, say, standard software development training that people go through?**
-
-GUINEVERE SAENGER: People tend to really connect the dots when I tell them I used to be a musician. Of course, I still consider myself a musician, because you don't really ever stop being a musician. But they say, 'oh, yeah, music and math', and that's just a similar sort of brain. And that makes so much sense. And I think there's a little bit of a point to that. When you learn a piece of music, you have to start recognizing patterns incredibly quickly, almost intuitively.
-
-And I think that is the main skill that translates into programming— recognizing patterns, finding the things that work, finding the things that don't work. And for me, especially as a collaborative pianist, it's the communicating with people, the finding out what people really want, where something is going, how to figure out what the general direction is that we want to take, before we start writing the first line of code.
-
-**CRAIG BOX: In your experience at Ada or with other experiences you've had, have you been able to identify patterns in other backgrounds for people that you'd recommend, 'hey, you're good at music, so therefore you might want to consider doing something like a course in computer science'?**
-
-GUINEVERE SAENGER: Overall, I think ultimately writing code is just giving a set of instructions to a computer. And we do that in daily life all the time. We give instructions to our kids, we give instructions to our students. We do math, we write textbooks. We give instructions to a room full of people when you're in court as a lawyer.
-
-Actually, the entrance exam to Ada Developers Academy used to have questions from the [LSAT](https://en.wikipedia.org/wiki/Law_School_Admission_Test) on it to see if you were qualified to join the program. They changed that when I applied, but I think that's a thing that happened at one point. So, overall, I think software engineering is a much more varied field than we give it credit for, and that there are so many ways in which you can apply your so-called other skills and bring them under the umbrella of software engineering.
-
-**CRAIG BOX: I do think that programming is effectively half art and half science. There's creativity to be applied. There is perhaps one way to solve a problem most efficiently. But there are many different ways that you can choose to express how you compiled something down to that way.**
-
-GUINEVERE SAENGER: Yeah, I mean, that's definitely true. I think one way that you could probably prove that is that if you write code at work and you're working on something with other people, you can probably tell which one of your co-workers wrote which package, just by the way it's written, or how it is documented, or how it is styled, or any of those things. I really do think that the human character shines through.
-
-**ADAM GLICK: What got you interested in Kubernetes and open source?**
-
-GUINEVERE SAENGER: The honest answer is absolutely nothing. Going back to my programming school— and remember that I had to do a five-month internship as part of my training— the way that the internship works is that sponsor companies for the program get interns in according to how much they sponsored a specific cohort of students.
-
-So at the time, Samsung and SDS offered to host two interns for five months on their [Cloud Native Computing team](https://samsung-cnct.github.io/) and have that be their practical experience. So I go out of a Ruby on Rails full stack web development bootcamp and show up at my internship, and they said, "Welcome to Kubernetes. Try to bring up a cluster." And I said, "Kuber what?"
-
-**CRAIG BOX: We've all said that on occasion.**
-
-**ADAM GLICK: Trial by fire, wow.**
-
-GUINEVERE SAENGER: I will say that that entire team was absolutely wonderful, delightful to work with, incredibly helpful. And I will forever be grateful for all of the help and support that I got in that environment. It was a great place to learn.
-
-**CRAIG BOX: You now work on GitHub's Kubernetes infrastructure. Obviously, there was GitHub before there was a Kubernetes, so a migration happened. What can you tell us about the transition that GitHub made to running on Kubernetes?**
-
-GUINEVERE SAENGER: A disclaimer here— I was not at GitHub at the time that the transition to Kubernetes was made. However, to the best of my knowledge, the decision to transition to Kubernetes was made and people decided, yes, we want to try Kubernetes. We want to use Kubernetes. And mostly, the only decision left was, which one of our applications should we move over to Kubernetes?
-
-**CRAIG BOX: I thought GitHub was written on Rails, so there was only one application.**
-
-GUINEVERE SAENGER: [LAUGHING] We have a lot of supplementary stuff under the covers.
-
-**CRAIG BOX: I'm sure.**
-
-GUINEVERE SAENGER: But yes, GitHub is written in Rails. It is still written in Rails. And most of the supplementary things are currently running on Kubernetes. We have a fair bit of stuff that currently does not run on Kubernetes. Mainly, that is GitHub Enterprise related things. I would know less about that because I am on the platform team that helps people use the Kubernetes infrastructure. But back to your question, leadership at the time decided that it would be a good idea to start with GitHub the Rails website as the first project to move to Kubernetes.
-
-**ADAM GLICK: High stakes!**
-
-GUINEVERE SAENGER: The reason for this was that they decided if they were going to not start big, it really wasn't going to transition ever. It was really not going to happen. So they just decided to go all out, and it was successful, for which I think the lesson would probably be commit early, commit big.
-
-**CRAIG BOX: Are there any other lessons that you would take away or that you've learned kind of from the transition that the company made, and might be applicable to other people who are looking at moving their companies from a traditional infrastructure to a Kubernetes infrastructure?**
-
-GUINEVERE SAENGER: I'm not sure this is a lesson specifically, but I was on support recently, and it turned out that, due to unforeseen circumstances and a mix of human error, a bunch of the namespaces on one of our Kubernetes clusters got deleted.
-
-**ADAM GLICK: Oh, my.**
-
-GUINEVERE SAENGER: It should not have affected any customers, I should mention, at this point. But all in all, it took a few of us a few hours to almost completely recover from this event. I think that, without Kubernetes, this would not have been possible.
-
-**CRAIG BOX: Generally, deleting something like that is quite catastrophic. We've seen a number of other vendors suffer large outages when someone's done something to that effect, which is why we get [#hugops](https://twitter.com/hashtag/hugops) on Twitter all the time.**
-
-GUINEVERE SAENGER: People did send me #hugops, that is a thing that happened. But overall, something like this was an interesting stress test and sort of proved that it wasn't nearly as catastrophic as a worst case scenario.
-
-**CRAIG BOX: GitHub [runs its own data centers](https://githubengineering.com/githubs-metal-cloud/). Kubernetes was largely built for running on the cloud, but a lot of people do choose to run it on their own, bare metal. How do you manage clusters and provisioning of the machinery you run?**
-
-GUINEVERE SAENGER: When I started, my onboarding project was to deprovision an old cluster, make sure all the traffic got moved to somewhere where it would keep running, provision a new cluster, and then move website traffic onto the new cluster. That was a really exciting onboarding project. At the time, we provisioned bare metal machines using Puppet. We still do that to a degree, but I believe the team that now runs our computing resources actually inserts virtual machines as an extra layer between the bare metal and the Kubernetes nodes.
-
-Again, I was not intrinsically part of that decision, but my understanding is that it just makes for a greater reliability and reproducibility across the board. We've had some interesting hardware dependency issues come up, and the virtual machines basically avoid those.
-
-**CRAIG BOX: You've been working with Kubernetes for a couple of years now. How did you get involved in the release process?**
-
-GUINEVERE SAENGER: When I first started in the project, I started at the [special interest group for contributor experience](https://github.com/kubernetes/community/tree/master/sig-contributor-experience#readme), namely because one of my co-workers at the time, Aaron Crickenberger, was a big Kubernetes community person. Still is.
-
-**CRAIG BOX: We've [had him on the show](https://kubernetespodcast.com/episode/046-kubernetes-1.14/) for one of these very release interviews!**
-
-GUINEVERE SAENGER: In fact, this is true! So Aaron and I actually go way back to Samsung SDS. Anyway, Aaron suggested that I should write up a contribution to the Kubernetes project, and I said, me? And he said, yes, of course. You will be [speaking at KubeCon](https://www.youtube.com/watch?v=TkCDUFR6xqw), so you should probably get started with a PR or something. So I tried, and it was really, really hard. And I complained about it [in a public GitHub issue](https://github.com/kubernetes/community/issues/141), and people said, yeah. Yeah, we know it's hard. Do you want to help with that?
-
-And so I started getting really involved with the [process for new contributors to get started](https://github.com/kubernetes/community/tree/master/contributors/guide) and have successes, kind of getting a foothold into a project that's as large and varied as Kubernetes. From there on, I began to talk to people, get to know people. The great thing about the Kubernetes community is that there is so much mentorship to go around.
-
-**ADAM GLICK: Right.**
-
-GUINEVERE SAENGER: There are so many friendly people willing to help. It's really funny when I talk to other people about it. They say, what do you mean, your coworker? And I said, well, he's really a colleague. He really works for another company.
-
-**CRAIG BOX: He's sort-of officially a competitor.**
-
-GUINEVERE SAENGER: Yeah.
-
-**CRAIG BOX: But we're friends.**
-
-GUINEVERE SAENGER: But he totally helped me when I didn't know how to git patch my borked pull request. So that happened. And eventually, somebody just suggested that I start following along in the release process and shadow someone on their release team role. And that, at the time, was Tim Pepper, who was bug triage lead, and I shadowed him for that role.
-
-**CRAIG BOX: Another [podcast guest](https://kubernetespodcast.com/episode/010-kubernetes-1.11/) on the interview train.**
-
-GUINEVERE SAENGER: This is a pattern that probably will make more sense once I explain to you about the shadow process of the release team.
-
-**ADAM GLICK: Well, let's turn to the Kubernetes release and the release process. First up, what's new in this release of 1.17?**
-
-GUINEVERE SAENGER: We have only a very few new things. The one that I'm most excited about is that we have moved [IPv4 and IPv6 dual stack](https://github.com/kubernetes/enhancements/issues/563) support to alpha. That is the most major change, and it has been, I think, a year and a half in coming. So this is the very first cut of that feature, and I'm super excited about that.
-
-**CRAIG BOX: The people who have been promised IPv6 for many, many years and still don't really see it, what will this mean for them?**
-
-**ADAM GLICK: And most importantly, why did we skip IPv5 support?**
-
-GUINEVERE SAENGER: I don't know!
-
-**CRAIG BOX: Please see [the appendix to this podcast](https://softwareengineering.stackexchange.com/questions/185380/ipv4-to-ipv6-where-is-ipv5) for technical explanations.**
-
-GUINEVERE SAENGER: Having a dual stack configuration obviously enables people to have a much more flexible infrastructure and not have to worry so much about making decisions that will become outdated or that may be over-complicated. This basically means that pods can have dual stack addresses, and nodes can have dual stack addresses. And that basically just makes communication a lot easier.
-
-**CRAIG BOX: What about features that didn't make it into the release? We had a conversation with Lachie in the [1.16 interview](https://kubernetespodcast.com/episode/072-kubernetes-1.16/), where he mentioned [sidecar containers](https://github.com/kubernetes/enhancements/blob/master/keps/sig-apps/sidecarcontainers.md). They unfortunately didn't make it into that release. And I see now that they haven't made this one either.**
-
-GUINEVERE SAENGER: They have not, and we are actually currently undergoing an effort of tracking features that flip multiple releases.
-
-As a community, we need everyone's help. There are a lot of features that people want. There is also a lot of cleanup that needs to happen. And we have started talking at previous KubeCons repeatedly about problems with maintainer burnout, reviewer burnout, have a hard time finding reviews for your particular contributions, especially if you are not an entrenched member of the community. And it has become very clear that this is an area where the entire community needs to improve.
-
-So the unfortunate reality is that sometimes life happens, and people are busy. This is an open source project. This is not something that has company mandated OKRs. Particularly during the fourth quarter of the year in North America, but around the world, we have a lot of holidays. It is the end of the year. Kubecon North America happened as well. This makes it often hard to find a reviewer in time or to rally the support that you need for your enhancement proposal. Unfortunately, slipping releases is fairly common and, at this point, expected. We started out with having 42 enhancements and [landed with roughly half of that](https://docs.google.com/spreadsheets/d/1ebKGsYB1TmMnkx86bR2ZDOibm5KWWCs_UjV3Ys71WIs/edit#gid=0).
-
-**CRAIG BOX: I was going to ask about the truncated schedule due to the fourth quarter of the year, where there are holidays in large parts of the world. Do you find that the Q4 release on the whole is smaller than others, if not for the fact that it's some week shorter?**
-
-GUINEVERE SAENGER: Q4 releases are shorter by necessity because we are trying to finish the final release of the year before the end of the year holidays. Often, releases are under pressure of KubeCons, during which finding reviewers or even finding the time to do work can be hard to do, if you are attending. And even if you're not attending, your reviewers might be attending.
-
-It has been brought up last year to make the final release more of a stability release, meaning no new alpha features. In practice, for this release, this is actually quite close to the truth. We have four features graduating to beta and most of our features are graduating to stable. I am hoping to use this as a precedent to change our process to make the final release a stability release from here on out. The timeline fits. The past experience fits this model.
-
-**ADAM GLICK: On top of all of the release work that was going on, there was also KubeCon that happened. And you were involved in the [contributor summit](https://github.com/kubernetes/community/tree/master/events/2019/11-contributor-summit). How was the summit?**
-
-GUINEVERE SAENGER: This was the first contributor summit where we had an organized events team with events organizing leads, and handbooks, and processes. And I have heard from multiple people— this is just word of mouth— that it was their favorite contributor summit ever.
-
-**CRAIG BOX: Was someone allocated to hat production? [Everyone had sailor hats](https://flickr.com/photos/143247548@N03/49093218951/).**
-
-GUINEVERE SAENGER: Yes, the entire event staff had sailor hats with their GitHub handle on them, and it was pretty fantastic. You can probably see me wearing one in some of the pictures from the contributor summit. That literally was something that was pulled out of a box the morning of the contributor summit, and no one had any idea. But at first, I was a little skeptical, but then I put it on and looked at myself in the mirror. And I was like, yes. Yes, this is accurate. We should all wear these.
-
-**ADAM GLICK: Did getting everyone together for the contributor summit help with the release process?**
-
-GUINEVERE SAENGER: It did not. It did quite the opposite, really. Well, that's too strong.
-
-**ADAM GLICK: Is that just a matter of the time taken up?**
-
-GUINEVERE SAENGER: It's just a completely different focus. Honestly, it helped getting to know people face-to-face that I had currently only interacted with on video. But we did have to cancel the release team meeting the day of the contributor summit because there was kind of no sense in having it happen. We moved it to the Tuesday, I believe.
-
-**CRAIG BOX: The role of the release team leader has been described as servant leadership. Do you consider the position proactive or reactive?**
-
-GUINEVERE SAENGER: Honestly, I think that depends on who's the release team lead, right? There are some people who are very watchful and look for trends, trying to detect problems before they happen. I tend to be in that camp, but I also know that sometimes it's not possible to predict things. There will be last minute bugs sometimes, sometimes not. If there is a last minute bug, you have to be ready to be on top of that. So for me, the approach has been I want to make sure that I have my priorities in order and also that I have backups in case I can't be available.
-
-**ADAM GLICK: What was the most interesting part of the release process for you?**
-
-GUINEVERE SAENGER: A release lead has to have served in other roles on the release team prior to being release team lead. To me, it was very interesting to see what other roles were responsible for, ones that I hadn't seen from the inside before, such as docs, CI signal. I had helped out with CI signal for a bit, but I want to give a big shout out to CI signal lead, Alena Varkockova, who was able to communicate effectively and kindly with everyone who was running into broken tests, failing tests. And she was very effective in getting all of our tests up and running.
-
-So that was actually really cool to see. And yeah, just getting to see more of the workings of the team, for me, it was exciting. The other big exciting thing, of course, was to see all the changes that were going in and all the efforts that were being made.
-
-**CRAIG BOX: The release lead for 1.18 has just been announced as [Jorge Alarcon](https://twitter.com/alejandrox135). What are you going to put in the proverbial envelope as advice for him?**
-
-GUINEVERE SAENGER: I would want Jorge to be really on top of making sure that every Special Interest Group that enters a change, that has an enhancement for 1.18, is on top of the timelines and is responsive. Communication tends to be a problem. And I had hinted at this earlier, but some enhancements slipped simply because there wasn't enough reviewer bandwidth.
-
-Greater communication of timelines and just giving people more time and space to be able to get in their changes, or at least, seemingly give them more time and space by sending early warnings, is going to be helpful. Of course, he's going to have a slightly longer release, too, than I did. This might be related to a unique Q4 challenge. Overall, I would encourage him to take more breaks, to rely more on his release shadows, and split out the work in a fashion that allows everyone to have a turn and everyone to have a break as well.
-
-**ADAM GLICK: What would your advice be to someone who is hearing your experience and is inspired to get involved with the Kubernetes release or contributer process?**
-
-GUINEVERE SAENGER: Those are two separate questions. So let me tackle the Kubernetes release question first. Kubernetes [SIG Release](https://github.com/kubernetes/sig-release/#readme) has, in my opinion, a really excellent onboarding program for new members. We have what is called the [Release Team Shadow Program](https://github.com/kubernetes/sig-release/blob/master/release-team/shadows.md). We also have the Release Engineering Shadow Program, or the Release Management Shadow Program. Those are two separate subprojects within SIG Release. And each subproject has a team of roles, and each role can have two to four shadows that are basically people who are part of that role team, and they are learning that role as they are doing it.
-
-So for example, if I am the lead for bug triage on the release team, I may have two, three or four people that I closely work with on the bug triage tasks. These people are my shadows. And once they have served one release cycle as a shadow, they are now eligible to be lead in that role. We have an application form for this process, and it should probably be going up in January. It usually happens the first week of the release once all the release leads are put together.
-
-**CRAIG BOX: Do you think being a member of the release team is something that is a good first contribution to the Kubernetes project overall?**
-
-GUINEVERE SAENGER: It depends on what your goals are, right? I believe so. I believe, for me, personally, it has been incredibly helpful looking into corners of the project that I don't know very much about at all, like API machinery, storage. It's been really exciting to look over all the areas of code that I normally never touch.
-
-It depends on what you want to get out of it. In general, I think that being a release team shadow is a really, really great on-ramp to being a part of the community because it has a paved path solution to contributing. All you have to do is show up to the meetings, ask questions of your lead, who is required to answer those questions.
-
-And you also do real work. You really help, you really contribute. If you go across the issues and pull requests in the repo, you will see, 'Hi, my name is so-and-so. I am shadowing the CI signal lead for the current release. Can you help me out here?' And that's a valuable contribution, and it introduces people to others. And then people will recognize your name. They'll see a pull request by you, and they're like oh yeah, I know this person. They're legit.

-**Author**: Craig Box (Google)
-
-The start of the COVID-19 pandemic couldn't delay the release of Kubernetes 1.18, but unfortunately [a small bug](https://github.com/kubernetes/utils/issues/141) could — thankfully only by a day.  This was the last cat that needed to be herded by 1.18 release lead [Jorge Alarcón](https://twitter.com/alejandrox135) before the [release on March 25](https://kubernetes.io/blog/2020/03/25/kubernetes-1-18-release-announcement/).
-
-One of the best parts about co-hosting the weekly [Kubernetes Podcast from Google](https://kubernetespodcast.com/) is the conversations we have with the people who help bring Kubernetes releases together. [Jorge was our guest on episode 96](https://kubernetespodcast.com/episode/096-kubernetes-1.18/) back in March, and [just like last week](https://kubernetes.io/blog/2020/07/27/music-and-math-the-kubernetes-1.17-release-interview/) we are delighted to bring you the transcript of this interview.
-
-If you'd rather enjoy the "audiobook version", including another interview when 1.19 is released later this month, [subscribe to the show](https://kubernetespodcast.com/subscribe/) wherever you get your podcasts.
-
-In the last few weeks, we've talked to long-time Kubernetes contributors and SIG leads [David Oppenheimer](https://kubernetespodcast.com/episode/114-scheduling/), [David Ashpole](https://kubernetespodcast.com/episode/113-instrumentation-and-cadvisor/) and [Wojciech Tyczynski](https://kubernetespodcast.com/episode/111-scalability/). All are worth taking the dog for a longer walk to listen to!

-
-**ADAM GLICK: You're a former physicist. I have to ask, what kind of physics did you work on?**
-
-JORGE ALARCÓN: Back in my days of math and all that, I used to work in [computational biology](https://en.wikipedia.org/wiki/Computational_biology) and a little bit of high energy physics. Computational biology was, for the most part, what I spent most of my time on. And it was essentially exploring the big idea of we have the structure of proteins. We know what they're made of. Now, based on that structure, we want to be able to predict [how they're going to fold](https://en.wikipedia.org/wiki/Protein_folding) and how they're going to behave, which essentially translates into the whole idea of designing pharmaceuticals, designing vaccines, or anything that you can possibly think of that has any connection whatsoever to a living organism.
-
-**ADAM GLICK: That would seem to ladder itself well into maybe going to something like bioinformatics. Did you take a tour into that, or did you decide to go elsewhere directly?**
-
-JORGE ALARCÓN: It is related, and I worked a little bit with some people that did focus on bioinformatics on the field specifically, but I never took a detour into it. Really, my big idea with computational biology, to be honest, it wasn't even the biology. That's usually what sells it, what people are really interested in, because protein engineering, all the cool and amazing things that you can do.
-
-Which is definitely good, and I don't want to take away from it. But my big thing is because biology is such a real thing, it is amazingly complicated. And the math— the models that you have to design to study those systems, to be able to predict something that people can actually experiment and measure, it just captivated me. The level of complexity, the beauty, the mechanisms, all the structures that you see once you got through the math and look at things, it just kind of got to me.
-
-**ADAM GLICK: How did you go from that world into the world of Kubernetes?**
-
-JORGE ALARCÓN: That's both a really boring story and an interesting one.
-
-[LAUGHING]
-
-I did my thing with physics, and it was good. It was fun. But at some point, I wanted— working in academia— at least my feeling for it is that generally all the people that you're surrounded with are usually academics. Just another bunch of physics, a bunch of mathematicians.
-
-But very seldom do you actually get the opportunity to take what you're working on and give it to someone else to use. Even with the mathematicians and physicists, the things that we're working on are super specialized, and you can probably find three, four, five people that can actually understand everything that you're saying. A lot of people are going to get the gist of it, but understanding the details, it's somewhat rare.
-
-One of the things that I absolutely love about tech, about software engineering, coding, all that, is how open and transparent everything is. You can write your library in Python, you can publish it, and suddenly the world is going to actually use it, actually consume it. And because normally, I've seen that it has a large avenue where you can work in something really complicated, you can communicate it, and people can actually go ahead and take it and run with it in their given direction. And that is kind of what happened.
-
-At some point, by pure accident and chance, I came across this group of people on the internet, and they were in the stages of making up this new group that's called [Data for Democracy](https://datafordemocracy.org/), a non-profit. And the whole idea was the internet, especially Twitter— that's how we congregated— Twitter, the internet. We have a ton of data scientists, people who work as software engineers, and the like. What if we all come together and try to solve some issues that actually affect the daily lives of people. And there were a ton of projects. Helping the ACLU gather data for something interesting that they were doing, gather data and analyze it for local governments— where do you have potholes, how much water is being consumed.
-
-Try to apply all the science that we knew, combined with all the code that we could write, and offer a good and digestible idea for people to say, OK, this makes sense, let's do something about it— policy, action, whatever. And I started working with this group, Data for Democracy— wonderful set of people. And the person who I believe we can blame for Data for Democracy— the one who got the idea and got it up and running, his name is Jonathan Morgan. And eventually, we got to work together. He started a startup, and I went to work with the startup. And that was essentially the thing that took me away from physics and into the world of software engineering— Data for Democracy, definitely.
-
-**ADAM GLICK: Were you using Kubernetes as part of that work there?**
-
-JORGE ALARCÓN: No, it was simple as it gets. You just try to get some data. You create a couple [IPython notebooks](https://ipython.org/), some setting up of really simple MySQL databases, and that was it.
-
-**ADAM GLICK: Where did you get started using Kubernetes? And was it before you started contributing to it and being a part, or did you decide to jump right in?**
-
-JORGE ALARCÓN: When I first started using Kubernetes, it was also on my first job. So there wasn't a lot of specific training in regards to software engineering or anything of the sort that I did before I actually started working as a software engineer. I just went from physicist to engineer. And in my days of physics, at least on the computer side, I was completely trained in the super old school system administrator, where you have your 10, 20 computers. You know physically where they are, and you have to connect the cables.
-
-**ADAM GLICK: All pets— all pets all the time.**
-
-JORGE ALARCÓN: [LAUGHING] You have to have your huge Python, bash scripts, three, five major versions, all because doing an upgrade will break something really important and you have no idea how to work on it. And that was my training. That was the way that I learned how to do things. Those were the kind of things that I knew how to do.
-
-And when I got to this company— startup— we were pretty much starting from scratch. We were building a couple applications. We work testing them, we were deploying them on a couple of managed instances. But like everything, there was a lot of toil that we wanted to automate. The whole issue of, OK, after days of work, we finally managed to get this version of the application up and running in these machines.
-
-It's open to the internet. People can test it out. But it turns out that it is now two weeks behind the latest on all the master branches for this repo, so now we want to update. And we have to go through the process of bringing it back up, creating new machines, do that whole thing. And I had no idea what Kubernetes was, to be honest. My boss at the moment mentioned it to me like, hey, we should use Kubernetes because apparently, Kubernetes is something that might be able to help us here. And we did some— I want to call it research and development.
-
-It was actually just making— again, startup, small company, small team, so really me just playing around with Kubernetes trying to get it to work, trying to get it to run. I was so lost. I had no idea what I was doing— not enough. I didn't have an idea of how Kubernetes was supposed to help me. And at that point, I did the best Googling that I could manage. Didn't really find a lot of examples. Didn't find a lot of blog posts. It was early.
-
-**ADAM GLICK: What time frame was this?**
-
-JORGE ALARCÓN: Three, four years ago, so definitely not 1.13. That's the best guesstimate that I can give at this point. But I wasn't able to find any good examples, any tutorials. The only book that I was able to get my hands on was the one written by Joe Beda, Kelsey Hightower, and I forget the other author. But what is it? "[Kubernetes— Up and Running](](http://shop.oreilly.com/product/0636920223788.do))"?
-
-And in general, right now I use it as reference— it's really good. But as a beginner, I still was lost. They give all these amazing examples, they provide the applications, but I had no idea why someone might need a Pod, why someone might need a Deployment. So my last resort was to try and find someone who actually knew Kubernetes.
-
-By accident, during my eternal Googling, I actually found a link to the [Kubernetes Slack](http://slack.kubernetes.io/). I jumped into the Kubernetes Slack hoping that someone might be able to help me out. And that was my entry point into the Kubernetes community. I just kept on exploring the Slack, tried to see what people were talking about, what they were asking to try to make sense of it, and just kept on iterating. And at some point, I think I got the hang of it.
-
-**ADAM GLICK: What made you decide to be a release lead?**
-
-JORGE ALARCÓN: The answer to this is my answer to why I have been contributing to Kubernetes. I really just want to be able to help out the community. Kubernetes is something that I absolutely adore.
-
-Comparing Kubernetes to old school system administration, a handful of years ago, it took me like a week to create a node for an application to run. It took me months to get something that vaguely looked like an Ingress resource— just setting up the Nginx, and allowing someone else to actually use my application. And the fact that I could do all of that in five minutes, it really captivated me. Plus I've got to blame it on the physics. The whole idea with physics, I really like the patterns, and I really like the design of Kubernetes.
-
-Once I actually got the hang of it, I loved the idea of how everything was designed, and I just wanted to learn a lot more about it. And I wanted to help the contributors. I wanted to help the people who actually build it. I wanted to help maintain it, and help provide the information for new contributors or new users. So instead of taking months for them to be up and running, let's just chat about what your issue is, and let's try to get a fix within the next hour or so.
-
-**ADAM GLICK: You work for a stealth startup right now. Is it fair to assume that they're using Kubernetes?**
-
-JORGE ALARCÓN: Yes—
-
-[LAUGHING]
-
-—for everything.
-
-**ADAM GLICK: Are you able to say what [Searchable](https://www.searchable.ai/) does?**
-
-JORGE ALARCÓN: The thing that we are trying to build is kind of like a search engine for your documents. Usually, if people have a question, they jump on Google. And for the most part, you're going to be able to get a good answer. You can ask something really random, like 'what is the weight of an elephant?'
-
-Which, if you think about it, it's kind of random, but Google is going to give you an answer. And the thing that we are trying to build is something similar to that, but for files. So essentially, a search engine for your files. And most people, you have your local machine loaded up with— at least mine, I have a couple tens of gigabytes of different files.
-
-I have Google Drive. I have a lot of documents that live in my email and the like. So the idea is to kind of build a search engine that is going to be able to connect all of those pieces. And besides doing simple word searches— for example, 'Kubernetes interview', and bring me the documents that we're looking at with all the questions— I can also ask things like what issue did I find last week while testing Prometheus. And it's going to be able to read my files, like through natural language processing, understand it, and be able to give me an answer.
-
-**ADAM GLICK: It is a Google for your personal and non-public information, essentially?**
-
-JORGE ALARCÓN: Hopefully.
-
-**ADAM GLICK: Is the work that you do with Kubernetes as the release lead— is that part of your day job, or is that something that you're doing kind of nights and weekends separate from your day job?**
-
-JORGE ALARCÓN: Both. Strictly speaking, my day job is just keep working on the application, build the things that it needs, maintain the infrastructure, and all that. When I started working at the company— which by the way, the person who brought me into the company was also someone that I met from my days in Data for Democracy— we started talking about the work.
-
-I mentioned that I do a lot of work with the Kubernetes community and if it was OK that I continue doing it. And to my surprise, the answer was not only a yes, but yeah, you can do it during your day work. And at least for the time being, I just balance— I try to keep things organized.
-
-Some days I just focus on Kubernetes. Some mornings I do Kubernetes. And then afternoon, I do Searchable, vice-versa, or just go back and forth, and try to balance the work as much as possible. But being release lead, definitely, it is a lot, so nights and weekends.
-
-**ADAM GLICK: How much time does it take to be the release lead?**
-
-JORGE ALARCÓN: It varies, but probably, if I had to give an estimate, at the very least you have to be able to dedicate four hours most days.
-
-**ADAM GLICK: Four hours a day?**
-
-JORGE ALARCÓN: Yeah, most days. It varies a lot. For example, at the beginning of the release cycle, you don't need to put in that much work because essentially, you're just waiting and helping people get set up, and people are writing their [Kubernetes Enhancement Proposals](https://github.com/kubernetes/enhancements/tree/master/keps), they are implementing it, and you can answer some questions. It's relatively easy, but for the most part, a lot of the time the four hours go into talking with people, just making sure that, hey, are people actually writing their enhancements, do we have all the enhancements that we want. And most of those fours hours, going around, chatting with people, and making sure that things are being done. And if, for some reason, someone needs help, just directing them to the right place to get their answer.
-
-**ADAM GLICK: What does Searchable get out of you doing this work?**
-
-JORGE ALARCÓN: Physically, nothing. The thing that we're striving for is to give back to the community. My manager/boss/homeslice— I told him I was going to call him my homeslice— both of us have experience working in open source. At some point, he was also working on a project that I'm probably going to mispronounce, but Mahout with Apache.
-
-And he also has had this experience. And both of us have this general idea and strive to build something for Searchable that's going to be useful for people, but also build knowledge, build guides, build applications that are going to be useful for the community. And at least one of the things that I was able to do right now is be the lead for the Kubernetes team. And this is a way of giving back to the community. We're using Kubernetes to run our things, so let's try to balance how things work.
-
-**ADAM GLICK: Lachlan Evenson was the release lead on 1.16 as well as [our guest back in episode 72](https://kubernetespodcast.com/episode/072-kubernetes-1.16/), and he's returned on this release as the [emeritus advisor](https://github.com/kubernetes/sig-release/tree/master/release-team/role-handbooks/emeritus-adviser). What did you learn from him?**
-
-JORGE ALARCÓN: Oh, everything. And it actually all started back on 1.16. So like you said, an amazing person— he's an amazing individual. And it's truly an opportunity to be able to work with him. During 1.16, I was the CI Signal lead, and Lachie is very hands on.
-
-He's not the kind of person to just give you a list of things and say, do them. He actually comes to you, has a conversation, and he works with you more than anything. And when we were working together on 1.16, I got to learn a lot from him in terms of CI Signal. And especially because we talked about everything just to make sure that 1.16 was ready to go, I also got to pick up a couple of things that a release lead has to know, has to be able to do, has to work on to get a release out the door.
-
-And now, during this release, there is a lot of information that's really useful, and there's a lot of advice and general wisdom that comes in handy. For most of the things that impact a lot of things, we are always in communication. Like, I'm doing this, you're doing that, advice. And essentially, every single thing that we do is pretty much a code review. You do it, and then you wait for someone else to give you comments. And that's been a strong part of our relationship working.
-
-**ADAM GLICK: What would you say the theme for this release is?**
-
-JORGE ALARCÓN: I think one of the themes is "fit and finish". There are a lot of features that we are bumping from alpha to beta, from beta to stable. And we want to make sure that people have a good user experience. Operators and developers alike just want to get rid of as many bugs as possible, improve the flow of things.
-
-But the other really cool thing is we have about an equal distribution between alpha, beta, and stable. We are also bringing up a lot of new features. So besides making Kubernetes more stable for all the users that are already using it, we are working on bringing up new things that people can try out for the next release and see how it goes in the future.
-
-**ADAM GLICK: Did you have a release team mascot?**
-
-JORGE ALARCÓN: Kind of.
-
-**ADAM GLICK: Who/what was it?**
-
-JORGE ALARCÓN: [LAUGHING] I say kind of because I'm using the mascot in the [logo](https://twitter.com/KubernetesPod/status/1242953121380392963), and the logo is inspired by the Large Hadron Collider.
-
-**ADAM GLICK: Oh, fantastic.**
-
-JORGE ALARCÓN: Being the release lead, I really had to take a chance on this opportunity to use the LHC as the mascot.
-
-**ADAM GLICK: We've had [some of the folks from the LHC on the show](https://kubernetespodcast.com/episode/062-cern/), and I know they listen, and they will be thrilled with that.**
-
-JORGE ALARCÓN: [LAUGHING] Hopefully, they like the logo.
-
-**ADAM GLICK: If you look at this release, what part of this release, what thing that has been added to it are you personally most excited about?**
-
-JORGE ALARCÓN: Like a parent can't choose which child is his or her favorite, you really can't choose a specific thing.
-
-**ADAM GLICK: We have been following online and in the issues an enhancement that's called [sidecar containers](https://github.com/kubernetes/enhancements/issues/753). You'd be able to mark the order of containers starting in a pod. Tim Hockin posted [a long comment on behalf of a number of SIG Node contributors](https://github.com/kubernetes/enhancements/issues/753#issuecomment-597372056) citing social, procedural, and technical concerns about what's going on with that— in particular, that it moved out of 1.18 and is now moving to 1.19. Did you have any thoughts on that?**
-
-JORGE ALARCÓN: The sidecar enhancement has definitely been an interesting one. First off, thank you very much to Joseph Irving, the author of the KEP. And thank you very much to Tim Hockin, who voiced out the point of view of the approvers, maintainers of SIG Node. And I guess a little bit of context before we move on is, in the Kubernetes community, we have contributors, we have reviewers, and we have approvers.
-
-Contributors are people who write PRs, who file issues, who troubleshoot issues. Reviewers are contributors who focus on one or multiple specific areas within the project, and then approvers are maintainers for the specific area, for one or multiple specific areas, of the project. So you can think of approvers as people who have write access in a repo or someplace within a repo.
-
-The issue with the sidecar enhancement is that it has been deferred for multiple releases now, and that's been because there hasn't been a lot of collaboration between the KEP authors and the approvers for specific parts of the project. Something worthwhile to mention— and this was brought up during the original discussion— is this can obviously be frustrating for both contributors and for approvers. From the contributor's side of things, you are working on something. You are doing your best to make sure that it works.
-
-And to build something that's going to be used by people, both from the approver side of things and, I think, for the most part, every single person in the Kubernetes community, we are all really excited to see this project grow. We want to help improve it, and we love when new people come in and work on new enhancements, bug fixes, and the like.
-
-But one of the limitations is the day only has so many hours, and there are only so many things that we can work on at a time. So people prioritize in whatever way works best, and some things just fall behind. And a lot of the time, the things that fall behind are not because people don't want them to continue moving forward, but it's just a limited amount of resources, a limited amount of people.
-
-And I think this discussion around the sidecar enhancement proposal has been very useful, and it points us to the need for more standardized mentoring programs. This is something that multiple SIGs are working on. For example, SIG Contribex, SIG Cluster Lifecycle, SIG Release. The idea is to standardize some sort of mentoring experience so that we can better prepare new contributors to become reviewers and ultimately approvers.
-
-Because ultimately at the end of the day, if we have more people who are knowledgeable about Kubernetes, or even some specific area of Kubernetes, we can better distribute the load, and we can better collaborate on whatever new things come up. I think the sidecar enhancement has shown us mentoring is something worthwhile, and we need a lot more of it. Because as much work as we do, more things are going to continue popping in throughout the project. And the more people we have who are comfortable working in these really complicated areas of Kubernetes, the better off that we are going to be.
-
-**ADAM GLICK: Was there any talk of delaying 1.18 due to the current worldwide health situation?**
-
-JORGE ALARCÓN: We thought about it, and the plan was to just wait and see how people felt. Tried make sure that people were comfortable continuing to work and all the people were landing in new enhancements, or fixing tests, or members of the release team who were making sure that things were happening. We wanted to see that people were comfortable, that they could continue doing their job. And for a moment, I actually thought about delaying just outright— we're going to give it more time, and hopefully at some point, things are going to work out.
-
-But people just continue doing their amazing work. There was no delay. There was no hitch throughout the process. So at some point, I just figured we stay with the current timeline and see how we went. And at this point, things are more or less set.
-
-**ADAM GLICK: Amazing power of a distributed team.**
-
-JORGE ALARCÓN: Yeah, definitely.
-
-[LAUGHING]
-
-**ADAM GLICK: [Taylor Dolezal was announced as the 1.19 release lead](https://twitter.com/alejandrox135/status/1239629281766096898). Do you know how that choice was made, and by whom?**
-
-JORGE ALARCÓN: I actually got to choose the lead. The practice is the current lead for the release team is going to look at people and see, first off, who's interested and out of the people interested, who can do the job, who's comfortable enough with the release team, with the Kubernetes community at large who can actually commit the amount of hours throughout the next, hopefully, three months.
-
-And for one, I think Taylor has been part of my team. So there is the release team. Then the release team has multiple subgroups. One of those subgroups is actually just for me and my shadows. So for this release, it was mrbobbytables and Taylor. And Taylor volunteered to take over 1.19, and I'm sure that he will do an amazing job.
-
-**ADAM GLICK: I am as well. What advice will you give Taylor?**
-
-JORGE ALARCÓN: Over-communicate as much as possible. Normally, if you made it to the point that you are the lead for a release, or even the shadow for a release, you more or less are familiar with a lot of the work— CI Signal, enhancements, documentation, and the like. And a lot of people, if they know how to do their job, they might tell themselves, yeah, I could do it— no need to worry about it. I'm just going to go ahead and sign this PR, debug this test, whatever.
-
-But one of the interesting aspects is whenever we are actually working in a release, 50% of the work has to go into actually making the release happen. The other 50% of the work has to go into mentoring people, and making sure the newcomers, new members are able to learn everything that they need to learn to do your job, you being in the lead for a subgroup or the entire team. And whenever you actually see that things need to happen, just over-communicate.
-
-Try to provide the opportunity for someone else to do the work, and over-communicate with them as much as possible to make sure that they are learning whatever it is that they need to learn. If neither you or the other person knows what's going on, then I can over-communicate, so someone hopefully will see your messages and come to the rescue. That happens a lot. There's a lot of really nice and kind people who will come out and tell you how something works, help you fix it.
-
-**ADAM GLICK: If you were to sum up your experience running this release, what would it be?**
-
-JORGE ALARCÓN: It's been super fun and a little bit stressing, to be honest. Being the release lead is definitely amazing. You're kind of sitting at the center of Kubernetes.
-
-You not only see the people who are working on things— the things that are broken, and the users filling out issues, and saying what broke, and the like. But you also get the opportunity to work with a lot of people who do a lot of non-code related work. Docs is one of the most obvious things. There's a lot of work that goes into communications, contributor experience, public relations.
-
-And being connected, getting to talk with those people mostly every other day, it's really fun. It's a really good experience in terms of becoming a better contributor to the community, but also taking some of that knowledge home with you and applying it somewhere else. If you are a software engineer, if you are a project manager, whatever, it's amazing how much you can learn.
-
-**ADAM GLICK: I know the community likes to rotate around who are the release leads. But if you were given the opportunity to be a release lead for a future release of Kubernetes, would you do it again?**
-
-JORGE ALARCÓN: Yeah, it's a fun job. To be honest, it can be really stressing. Especially, as I mentioned, at some point, most of that work is just going to be talking with people, and talking requires a lot more thought and effort than just sitting down and thinking about things sometimes. And some of that can be really stressful.
-
-But the job itself, it is definitely fun. And at some distant point in the future, if for some reason it was a possibility, I will think about it. But definitely, as you mentioned, one thing that we try to do is cycle out, because I can have fun in it, and that's all good and nice. And hopefully I can help another release go out the door. But providing the opportunity for other people to learn I think is a lot more important than just being the lead itself.

-title: "Introducing Hierarchical Namespaces"
-date: 2020-08-14
---
-
-**Author**: Adrian Ludwin (Google)
-
-Safely hosting large numbers of users on a single Kubernetes cluster has always
-been a troublesome task. One key reason for this is that different organizations
-use Kubernetes in different ways, and so no one tenancy model is likely to suit
-everyone. Instead, Kubernetes offers you building blocks to create your own
-tenancy solution, such as Role Based Access Control (RBAC) and NetworkPolicies;
-the better these building blocks, the easier it is to safely build a multitenant
-cluster.
-
-# Namespaces for tenancy
-
-By far the most important of these building blocks is the namespace, which forms
-the backbone of almost all Kubernetes control plane security and sharing
-policies. For example, RBAC, NetworkPolicies and ResourceQuotas all respect
-namespaces by default, and objects such as Secrets, ServiceAccounts and
-Ingresses are freely usable _within_ any one namespace, but fully segregated
-from _other_ namespaces.
-
-Namespaces have two key properties that make them ideal for policy enforcement.
-Firstly, they can be used to **represent ownership**. Most Kubernetes objects
-_must_ be in a namespace, so if you use namespaces to represent ownership, you
-can always count on there being an owner.
-
-Secondly, namespaces have **authorized creation and use**. Only
-highly-privileged users can create namespaces, and other users require explicit
-permission to use those namespaces - that is, create, view or modify objects in
-those namespaces. This allows them to be carefully created with appropriate
-policies, before unprivileged users can create “regular” objects like pods and
-services.
-
-# The limits of namespaces
-
-However, in practice, namespaces are not flexible enough to meet some common use
-cases. For example, let’s say that one team owns several microservices with
-different secrets and quotas. Ideally, they should place these services into
-different namespaces in order to isolate them from each other, but this presents
-two problems.
-
-Firstly, these namespaces have no common concept of ownership, even though
-they’re both owned by the same team. This means that if the team controls
-multiple namespaces, not only does Kubernetes not have any record of their
-common owner, but namespaced-scoped policies cannot be applied uniformly across
-them.
-
-Secondly, teams generally work best if they can operate autonomously, but since
-namespace creation is highly privileged, it’s unlikely that any member of the
-dev team is allowed to create namespaces. This means that whenever a team wants
-a new namespace, they must raise a ticket to the cluster administrator. While
-this is probably acceptable for small organizations, it generates unnecessary
-toil as the organization grows.
-
-# Introducing hierarchical namespaces
-
-[Hierarchical
-namespaces](https://github.com/kubernetes-sigs/multi-tenancy/blob/master/incubator/hnc/docs/user-guide/concepts.md#basic)
-are a new concept developed by the [Kubernetes Working Group for Multi-Tenancy
-(wg-multitenancy)](https://github.com/kubernetes-sigs/multi-tenancy) in order to
-solve these problems. In its simplest form, a hierarchical namespace is a
-regular Kubernetes namespace that contains a small custom resource that
-identifies a single, optional, parent namespace. This establishes the concept of
-ownership _across_ namespaces, not just _within_ them.
-
-This concept of ownership enables two additional types of behaviours:
-
-* **Policy inheritance:** if one namespace is a child of another, policy objects
-  such as RBAC RoleBindings are [copied from the parent to the
-  child](https://github.com/kubernetes-sigs/multi-tenancy/blob/master/incubator/hnc/docs/user-guide/concepts.md#basic-propagation).
-* **Delegated creation:** you usually need cluster-level privileges to create a
-  namespace, but hierarchical namespaces adds an alternative:
-  [_subnamespaces_](https://github.com/kubernetes-sigs/multi-tenancy/blob/master/incubator/hnc/docs/user-guide/concepts.md#basic-subns),
-  which can be manipulated using only limited permissions in the parent
-  namespace.
-
-This solves both of the problems for our dev team. The cluster administrator can
-create a single “root” namespace for the team, along with all necessary
-policies, and then delegate permission to create subnamespaces to members of
-that team. Those team members can then create subnamespaces for their own use,
-without violating the policies that were imposed by the cluster administrators.
-
-# Hands-on with hierarchical namespaces
-
-Hierarchical namespaces are provided by a Kubernetes extension known as the
-[**Hierarchical Namespace
-Controller**](https://github.com/kubernetes-sigs/multi-tenancy/tree/master/incubator/hnc),
-or **HNC**. The HNC consists of two components:
-
-* The **manager** runs on your cluster, manages subnamespaces, propagates policy
-  objects, ensures that your hierarchies are legal and manages extension points.
-* The **kubectl plugin**, called `kubectl-hns`, makes it easy for users to
-  interact with the manager.
-
-Both can be easily installed from the [releases page of our
-repo](https://github.com/kubernetes-sigs/multi-tenancy/releases).
-
-Let’s see HNC in action. Imagine that I do not have namespace creation
-privileges, but I can view the namespace `team-a` and create subnamespaces
-within it<sup>[1](#note-1)</sup>. Using the plugin, I can now say:
-
-```bash
-$ kubectl hns create svc1-team-a -n team-a
-```
-
-This creates a subnamespace called `svc1-team-a`. Note that since subnamespaces
-are just regular Kubernetes namespaces, all subnamespace names must still be
-unique.
-
-I can view the structure of these namespaces by asking for a tree view:
-
-```bash
-$ kubectl hns tree team-a
-# Output:
-team-a
-└── svc1-team-a
-```
-
-And if there were any policies in the parent namespace, these now appear in the
-child as well<sup>[2](#note-2)</sup>. For example, let’s say that `team-a` had
-an RBAC RoleBinding called `sres`. This rolebinding will also be present in the
-subnamespace:
-
-```bash
-$ kubectl describe rolebinding sres -n svc1-team-a
-# Output:
-Name:         sres
-Labels:       hnc.x-k8s.io/inheritedFrom=team-a  # inserted by HNC
-Annotations:  <none>
-Role:
-  Kind:  ClusterRole
-  Name:  admin
-Subjects: ...
-```
-
-Finally, HNC adds labels to these namespaces with useful information about the
-hierarchy which you can use to apply other policies. For example, you can create
-the following NetworkPolicy:
-
-```yaml
-kind: NetworkPolicy
-apiVersion: networking.k8s.io/v1
-metadata:
-  name: allow-team-a
-  namespace: team-a
-spec:
-  ingress:
-  - from:
-    - namespaceSelector:
-        matchExpressions:
-          - key: 'team-a.tree.hnc.x-k8s.io/depth' # Label created by HNC
-            operator: Exists
-```
-
-This policy will both be propagated to all descendants of `team-a`, and will
-_also_ allow ingress traffic between all of those namespaces. The “tree” label
-can only be applied by HNC, and is guaranteed to reflect the latest hierarchy.
-
-You can learn all about the features of HNC from the [user
-guide](https://github.com/kubernetes-sigs/multi-tenancy/tree/master/incubator/hnc/docs/user-guide).
-
-# Next steps and getting involved
-
-If you think that hierarchical namespaces can work for your organization, [HNC
-v0.5.1 is available on
-GitHub](https://github.com/kubernetes-sigs/multi-tenancy/releases/tag/hnc-v0.5.1).
-We’d love to know what you think of it, what problems you’re using it to solve
-and what features you’d most like to see added. As with all early software, you
-should be cautious about using HNC in production environments, but the more
-feedback we get, the sooner we’ll be able to drive to HNC 1.0.
-
-We’re also open to additional contributors, whether it’s to fix or report bugs,
-or help prototype new features such as exceptions, improved monitoring,
-hierarchical resource quotas or fine-grained configuration.
-
-Please get in touch with us via our
-[repo](https://github.com/kubernetes-sigs/multi-tenancy), [mailing
-list](https://groups.google.com/g/kubernetes-wg-multitenancy) or on
-[Slack](https://kubernetes.slack.com/messages/wg-multitenancy) - we look forward
-to hearing from you!

-title: "Moving Forward From Beta"
-date: 2020-08-21
-slug: moving-forward-from-beta
---
-
-**Author**: Tim Bannister, The Scale Factory
-
-In Kubernetes, features follow a defined
-[lifecycle](/docs/reference/command-line-tools-reference/feature-gates/#feature-stages).
-First, as the twinkle of an eye in an interested developer. Maybe, then,
-sketched in online discussions, drawn on the online equivalent of a cafe
-napkin. This rough work typically becomes a
-[Kubernetes Enhancement Proposal](https://github.com/kubernetes/enhancements/blob/master/keps/0001-kubernetes-enhancement-proposal-process.md#kubernetes-enhancement-proposal-process) (KEP), and
-from there it usually turns into code.
-
-For Kubernetes v1.20 and onwards, we're focusing on helping that code
-graduate into stable features.
-
-That lifecycle I mentioned runs as follows:
-
-![Alpha → Beta → General Availability](feature_stages.svg)
-
-Usually, alpha features aren't enabled by default. You turn them on by setting a feature
-gate; usually, by setting a command line flag on each of the components that use the
-feature.
-
-(If you use Kubernetes through a managed service offering such as AKS, EKS, GKE, etc then
-the vendor who runs that service may have decided what feature gates are enabled for you).
-
-There's a defined process for graduating an existing, alpha feature into the beta phase.
-This is important because **beta features are enabled by default**, with the feature flag still
-there so cluster operators can opt out if they want.
-
-A similar but more thorough set of graduation criteria govern the transition to general
-availability (GA), also known as "stable". GA features are part of Kubernetes, with a
-commitment that they are staying in place throughout the current major version.
-
-Having beta features on by default lets Kubernetes and its contributors get valuable
-real-world feedback. However, there's a mismatch of incentives. Once a feature is enabled
-by default, people will use it. Even if there might be a few details to shake out,
-the way Kubernetes' REST APIs and conventions work mean that any future stable API is going
-to be compatible with the most recent beta API: your API objects won't stop working when
-a beta feature graduates to GA.
-
-For the API and its resources in particular, there's a much less strong incentive to move
-features from beta to GA than from alpha to beta. Vendors who want a particular feature
-have had good reason to help get code to the point where features are enabled by default,
-and beyond that the journey has been less clear.
-
-KEPs track more than code improvements. Essentially, anything that would need
-communicating to the wider community merits a KEP. That said, most KEPs cover
-Kubernetes features (and the code to implement them).
-
-You might know that [Ingress](/docs/concepts/services-networking/ingress/)
-has been in Kubernetes for a while, but did you realize that it actually went beta in 2015? To help
-drive things forward, Kubernetes' Architecture Special Interest Group (SIG) have a new approach in
-mind.
-
-## Avoiding permanent beta
-
-For Kubernetes REST APIs, when a new feature's API reaches beta, that starts a countdown.
-The beta-quality API now has **nine calendar months** to either:
- reach GA, and deprecate the beta, or
- have a new beta version (_and deprecate the previous beta_).
-
-To be clear, at this point **only REST APIs are affected**. For example, _APIListChunking_ is
-a beta feature but isn't itself a REST API. Right now there are no plans to automatically
-deprecate _APIListChunking_ nor any other features that aren't REST APIs.
-
-If a REST API reaches the end of that 9 month countdown, then the next Kubernetes release
-will deprecate that API version. There's no option for the REST API to stay at the same
-beta version beyond the first Kubernetes release to come out after the 9 month window.
-
-### What this means for you
-
-If you're using Kubernetes, there's a good chance that you're using a beta feature. Like
-I said, there are lots of them about.
-As well as Ingress, you might be using [CronJob](/docs/concepts/workloads/controllers/cron-jobs/),
-or [PodSecurityPolicy](/docs/concepts/policy/pod-security-policy/), or others.
-There's an even bigger chance that you're running on a control plane with at least one beta
-feature enabled.
-
-If you're using or generating Kubernetes manifests that use beta APIs like Ingress, you'll
-need to plan to revise those. The current APIs are going to be deprecated following a
-schedule (the 9 months I mentioned earlier) and after a further 9 months those deprecated
-APIs will be removed. At that point, to stay current with Kubernetes, you should already
-have migrated.
-
-### What this means for Kubernetes contributors
-
-The motivation here seems pretty clear: get features stable. Guaranteeing that beta
-features will be deprecated adds a pretty big incentive so that people who want the
-feature continue their effort until the code, documentation and tests are ready for this
-feature to graduate to stable, backed by several Kubernetes' releases of evidence in
-real-world use.
-
-### What this means for the ecosystem
-
-In my opinion, these harsh-seeming measures make a lot of sense, and are going to be
-good for Kubernetes. Deprecating existing APIs, through a rule that applies across all
-the different Special Interest Groups (SIGs), helps avoid stagnation and encourages
-fixes.
-
-Let's say that an API goes to beta and then real-world experience shows that it
-just isn't right - that, fundamentally, the API has shortcomings. With that 9 month
-countdown ticking, the people involved have the means and the justification to revise
-and release an API that deals with the problem cases. Anyone who wants to live with
-the deprecated API is welcome to - Kubernetes is open source - but their needs do not
-have to hold up progress on the feature.

  Lacerte’s strategy ultimately worked because of the very real impact the Kubernetes platform has had to deployment time. Due to less dependency on custom-made, brittle shell scripts with SCP commands, time to deploy a new version has shrunk from 4 hours to a few minutes. Additionally, the company invested a lot of effort to make things self-service for developers. "Onboarding a new service doesn’t require <a href="https://www.atlassian.com/software/jira">Jira</a> tickets or meeting with three different teams," says Lacerte. Today, the company sees 1,600 deployments per week, compared to 1-30 before.

  Williams and the rest of the platform team decided that the first step would be to start moving from private data centers to AWS. With a new microservice architecture in mind—and the freedom to implement what was best for the organization—they began using Docker containers. After looking into the various container orchestration options, they went with Kubernetes, even though it was still in beta at the time. "There was some debate whether we should build something ourselves, or just leverage that product and evolve with it," says Northwestern Mutual Cloud Native Engineer Frank Greco Jr. "Kubernetes has definitely been the right choice for us. It gave us that base framework so teams can be autonomous in what they’re building and deliver very quickly and frequently."<br><br>
 As early adopters, the team had to do a lot of work with Ansible scripts to stand up the cluster. "We had a lot of hard security requirements given the nature of our business," explains Bryan Pfremmer, App Platform Teams Manager, Northwestern Mutual. "We found ourselves running a configuration that very few other people ever tried." The client experience group was the first to use the new platform; today, a few hundred of the company’s 1,500 engineers are using it and more are eager to get on board.
-The results have been dramatic. Before, infrastructure deployments could take two weeks; now, it is done in a matter of minutes. Now with a focus on Infrastructure automation, and self-service, "You can take an app to production in that same day if you want to," says Pfremmer.
