Getting Started with Kubernetes
-By the end of this tutorial you will understand what Kubernetes does. You will also learn how to deploy, scale, update and debug containerized applications on a Kubernetes cluster using an interactive online terminal.
+Kubernetes Basics
+This tutorial provides a walkthrough of the basics of the Kubernetes cluster orchestration system. Each module contains some background information on major Kubernetes features and concepts, and includes an interactive online tutorial. These interactive tutorials let you manage a simple cluster and its containerized applications for yourself.
+Using the interactive tutorials, you can learn to:
+-
+
- Deploy a containerized application on a cluster +
- Scale the deployment +
- Update the containerized application with a new software version +
- Debug the containerized application +
The tutorials use Katacoda to run a virtual terminal in your web browser that runs Minikube, a small-scale local deployment of Kubernetes that can run anywhere. There's no need to install any software or configure anything; each interactive tutorial runs directly out of your web browser itself.

Why Kubernetes?
-Today users expect applications to be available 24/7, while developers expect to deploy new versions of those applications several times a day. The way we build software is moving in this direction, enabling applications to be released and updated in an easy and fast way without downtime. We also need to be able to scale application in line with the user demand and we expect them to make intelligent use of the available resources. Kubernetes is a platform designed to meet those requirements, using the experience accumulated by Google in this area, combined with best-of-breed ideas from the community.
+What can Kubernetes do for you?
+With modern web services, users expect applications to be available 24/7, and developers expect to deploy new versions of those applications several times a day. Containzerization helps package software to serve these goals, enabling applications to be released and updated in an easy and fast way without downtime. Kubernetes helps you make sure those containerized applications run where and when you want, and helps them find the resources and tools they need to work. Kubernetes is a production-ready, open source platform designed with the Google's accumulated experience in container orchestration, combined with best-of-breed ideas from the community.

+
+### Creating a service for an application running in five pods
+
+1. Run a Hello World application in your cluster:
+
+ kubectl run hello-world --replicas=5 --labels="run=load-balancer-example" --image=gcr.io/google-samples/node-hello:1.0 --port=8080
+
+ The preceding command creates a
+ [Deployment](/docs/user-guide/deployments/)
+ object and an associated
+ [ReplicaSet](/docs/user-guide/replicasets/)
+ object. The ReplicaSet has five
+ [Pods](/docs/user-guide/pods/),
+ each of which runs the Hello World application.
+
+1. Display information about the Deployment:
+
+ kubectl get deployments hello-world
+ kubectl describe deployments hello-world
+
+1. Display information about your ReplicaSet objects:
+
+ kubectl get replicasets
+ kubectl describe replicasets
+
+1. Create a Service object that exposes the deployment:
+
+ kubectl expose deployment hello-world --type=LoadBalancer --name=my-service
+
+1. Display information about the Service:
+
+ kubectl get services my-service
+
+ The output is similar to this:
+
+ NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
+ my-service 10.3.245.137 104.198.205.71 8080/TCP 54s
+
+ Note: If the external IP address is shown as , wait for a minute
+ and enter the same command again.
+
+1. Display detailed information about the Service:
+
+ kubectl describe services my-service
+
+ The output is similar to this:
+
+ Name: my-service
+ Namespace: default
+ Labels: run=load-balancer-example
+ Selector: run=load-balancer-example
+ Type: LoadBalancer
+ IP: 10.3.245.137

+ Session Affinity: None
+ Events:
+
+ Make a note of the external IP address exposed by your service. In this
+ example, the external IP address is 104.198.205.71. Also note
+ the value of Port. In this example, the port is 8080.
+

+ 10.0.0.6:8080,10.0.1.6:8080,10.0.1.7:8080 + 2 more. These are internal
+ addresses of the pods that are running the Hello World application. To
+ verify these are pod addresses, enter this command:
+
+ kubectl get pods --output=wide
+
+ The output is similar to this:
+
+ NAME ... IP NODE

+ hello-world-2895499144-segjf ... 10.0.2.5 gke-cluster-1-default-pool-e0b8d269-cpuc
+
+1. Use the external IP address to access the Hello World application:
+
+ curl http://:
+
+ where `` us the external IP address of your Service,
+ and `` is the value of `Port` in your Service description.
+
+ The response to a successful request is a hello message:
+
+ Hello Kubernetes!
+

+* Pin to a specific [generator](#generators) version, such as `kubectl run --generator=deployment/v1beta1`
+
+#### Generators
+
+`kubectl run` allows you to generate the following resources (using `--generator` flag):
+
+* Pod - use `run-pod/v1`.
+* Replication controller - use `run/v1`.
+* Deployment - use `deployment/v1beta1`.
+* Job (using `extension/v1beta1` endpoint) - use `job/v1beta1`.
+* Job - use `job/v1`.
+* ScheduledJob - use `scheduledjob/v2alpha1`.
+
+Additionally, if you didn't specify a generator flag, other flags will suggest using
+a specific generator. Below table shows which flags force using specific generators,
+depending on your cluster version:
+
+| Generated Resource | Cluster v1.4 | Cluster v1.3 | Cluster v1.2 | Cluster v1.1 and eariler |
+|:----------------------:|-----------------------|-----------------------|--------------------------------------------|--------------------------------------------|
+| Pod | `--restart=Never` | `--restart=Never` | `--generator=run-pod/v1` | `--restart=OnFailure` OR `--restart=Never` |
+| Replication Controller | `--generator=run/v1` | `--generator=run/v1` | `--generator=run/v1` | `--restart=Always` |
+| Deployment | `--restart=Always` | `--restart=Always` | `--restart=Always` | N/A |
+| Job | `--restart=OnFailure` | `--restart=OnFailure` | `--restart=OnFailure` OR `--restart=Never` | N/A |
+| Scheduled Job | `--schedule=` | N/A | N/A | N/A |
+
+Note that these flags will use a default generator only when you have not specified
+any flag. This also means that combining `--generator` with other flags won't
+change the generator you specified. For example, in a 1.4 cluster, if you specify
+`--restart=Always`, a Deployment will be created; if you specify `--restart=Always`
+and `--generator=run/v1`, a Replication Controller will be created instead.
+This becomes handy if you want to pin to a specific behavior with the generator,
+even when the defaulted generator is changed in the future.
+
+Finally, the order in which flags set the generator is: schedule flag has the highest
+priority, then restart policy and finally the generator itself.
+
+If in doubt about the final resource being created, you can always use `--dry-run`
+flag, which will provide the object to be submitted to the cluster.

This purpose of this guide is to help you become familiar with the runtime initialization of [Pet Sets](/docs/user-guide/petset). This guide assumes the same prerequisites, and uses the same terminology as the [Pet Set user document](/docs/user-guide/petset).
-The most common way to initialize the runtime in a containerized environment, is through a custom [entrypoint](https://docs.docker.com/engine/reference/builder/#entrypoint). While this is not necessarily bad, making your application pid 1, and treating containers as processes in general is good for a few reasons outside the scope of this document. Doing so allows you to run docker images from third-party vendors without modification. We will not be writing custom entrypoints for this example, but using a feature called [init containers](http://releases.k8s.io/{{page.githubbranch}}/docs/proposals/container-init.md), to explain 2 common patterns that come up deploying Pet Sets.

-Kubernetes now includes an alpha feature known as **init containers**, which are one or more containers in a pod that get a chance to run and initialize shared volumes prior to the other application containers starting. An init container is exactly like a regular container, except that it always runs to completion and each init container must complete successfully before the next one is started. If the init container fails (exits with a non-zero exit code) on a `RestartNever` pod the pod will fail - otherwise it will be restarted until it succeeds or the user deletes the pod.

+The status of the init containers is returned as another annotation - `pod.beta.kubernetes.io/init-container-statuses` -- as an array of the container statuses (similar to the `status.containerStatuses` field).
Init containers support all of the same features as normal containers, including resource limits, volumes, and security settings. The resource requests and limits for an init container are handled slightly different than normal containers since init containers are run one at a time instead of all at once - any limits or quotas will be applied based on the largest init container resource quantity, rather than as the sum of quantities. Init containers do not support readiness probes since they will run to completion before the pod can be ready.
