Sync up between dev-1.18 and master branches (#19055)
* Fixed outdated ECR credential debug message (#18631) * Fixed outdated ECR credential debug message The log message for troubleshooting kubelet auto fetching ECR credentils issue has been changed (noticed since 1.14), and the new message reads like this when verbose log level is set to 3: - `aws_credentials.go:109] unable to get ECR credentials from cache, checking ECR API` - `aws_credentials.go:116] Got ECR credentials from ECR API for <Your ECR AWS Account ID>.dkr.ecr.us-east-1.amazonaws.com` This is based on the kubelet source code: https://github.com/kubernetes/kubernetes/blob/release-1.14/pkg/credentialprovider/aws/aws_credentials.go#L91 This PR is to fix this and to avoid confusion for more people who are troubleshooting the kubelet ECR issue. * Update content/en/docs/concepts/containers/images.md Co-Authored-By: Tim Bannister <tim@scalefactory.com> Co-authored-by: Tim Bannister <tim@scalefactory.com> * Fix deployment name in docs/tasks/administer-cluster/dns-horizontal-autoscaling.md (#18772) * ru/docs/tutorials/hello-minikube.md: sync with English translation.

Given that `kubectl` is not a [command line interface (CLI)](https://en.wikipedia.org/wiki/Command-line_interface), I suggest calling it what it is -- a control utility (ctl = control). The term "tool" is commonly used in place of "utility," including the `kubectl` docs. A CLI presents the user with a command prompt at which the user can enter multiple command lines that a command-line interpreter interprets and processes. Think of `bash`, `emacs`, or a SQL shell. Since `kubectl` is not run in a shell, it is not a CLI. Here are related docs that correctly refer to `kubectl` as a "command-line tool": - https://kubernetes.io/docs/reference/tools/#kubectl - https://kubernetes.io/docs/reference/glossary/?fundamental=true#term-kubectl -

_pod_ (就像在鲸鱼荚或者豌豆荚中)是一组(一个或多个)容器(例如 Docker 容器),这些容器有共享存储、网络、以及怎样运行这些容器的声明。Pod 的内容总是共同定位和共同调度,并且在共享的上下文中运行。

Pod 以特定于应用的“逻辑主机”为模型,它包含一个或多个应用容器,这些容器是相对紧密的耦合在一起;在容器出现之前,在相同的物理机或虚拟机上运行意味着在相同的逻辑主机上运行。

|
||||
Pod 是形成内聚服务单元的多个协作过程模式的模型。它们提供了一个比它们的应用组成集合更高级的抽象,从而简化了应用的部署和管理。Pod 可以用作部署单元、水平缩放和复制。在 Pod中,多个容器的共同定位(协同调度)、共享命运(例如,终止)、协调复制、资源共享和依赖项管理都是自动处理的。

### Resource sharing and communication
|
||||
|
||||
Pods enable data sharing and communication among their constituents.
|
||||
|
||||
The applications in a pod all use the same network namespace (same IP and port
|
||||
space), and can thus "find" each other and communicate using `localhost`.
|
||||
Because of this, applications in a pod must coordinate their usage of ports.
|
||||
Each pod has an IP address in a flat shared networking space that has full
|
||||
communication with other physical computers and pods across the network.

## Termination of Pods
|
||||
|
||||
Because pods represent running processes on nodes in the cluster, it is important to allow those processes to gracefully terminate when they are no longer needed (vs being violently killed with a KILL signal and having no chance to clean up). Users should be able to request deletion and know when processes terminate, but also be able to ensure that deletes eventually complete. When a user requests deletion of a pod, the system records the intended grace period before the pod is allowed to be forcefully killed, and a TERM signal is sent to the main process in each container. Once the grace period has expired, the KILL signal is sent to those processes, and the pod is then deleted from the API server. If the Kubelet or the container manager is restarted while waiting for processes to terminate, the termination will be retried with the full grace period.

因为 Pod 代表在集群中的节点上运行的进程,所以当不再需要这些进程时(与被 KILL 信号粗暴地杀死并且没有机会清理相比),允许这些进程优雅地终止是非常重要的。
|
||||
用户应该能够请求删除并且知道进程何时终止,但是也能够确保删除最终完成。当用户请求删除 Pod 时,系统会记录在允许强制删除 Pod 之前所期望的宽限期,并向每个容器中的主进程发送 TERM 信号。一旦过了宽限期,KILL 信号就发送到这些进程,然后就从 API 服务器上删除 Pod。如果 Kubelet 或容器管理器在等待进程终止时发生重启,则终止操作将以完整的宽限期进行重试。

1. Pod shows up as "Terminating" when listed in client commands

### Force deletion of pods
|
||||
|
||||
Force deletion of a Pod is defined as deletion of a Pod from the cluster state and etcd immediately. When a force deletion is performed, the API server does not wait for confirmation from the kubelet that the Pod has been terminated on the node it was running on. It removes the Pod in the API immediately so a new Pod can be created with the same name. On the node, Pods that are set to terminate immediately will still be given a small grace period before being force killed.
|
||||
|
||||
Force deletions can be potentially dangerous for some pods and should be performed with caution. In case of StatefulSet pods, please refer to the task documentation for [deleting Pods from a StatefulSet](/docs/tasks/run-application/force-delete-stateful-set-pod/).

### Pod 的强制删除

强制删除pod定义为从集群状态和 etcd 中立即删除 Pod。当执行强制删除时,apiserver 并不会等待 kubelet 的确认信息,该 Pod 已在所运行的节点上被终止了。强制删除操作从 API 中立即清除了 Pod, 因此可以用相同的名称创建一个新的 Pod。在节点上,设置为立即终止的 Pod 还是会在被强制删除前设置一个小的宽限期。

强制删除 Pod 被定义为从集群状态与 etcd 中立即删除 Pod。当执行强制删除时,API 服务器并不会等待 kubelet 的确认信息,该 Pod 已在所运行的节点上被终止了。强制执行删除操作会从 API 服务器中立即清除 Pod, 因此可以用相同的名称创建一个新的 Pod。在节点上,设置为立即终止的 Pod 还是会在被强制删除前设置一个小的宽限期。
|
||||
|
||||
强制删除对某些 Pod 可能具有潜在危险,因此应该谨慎地执行。对于 StatefulSet 管理的 Pod,请参考 [从 StatefulSet 中删除 Pod](/docs/tasks/run-application/force-delete-stateful-set-pod/)的任务文档。
|
||||
<!--
|
||||
Force deletions can be potentially dangerous for some Pods and should be performed with caution. In case of StatefulSet Pods, please refer to the task documentation for [deleting Pods from a StatefulSet](/docs/tasks/run-application/force-delete-stateful-set-pod/).

## Privileged mode for pod containers
|
||||
|
||||
From Kubernetes v1.1, any container in a pod can enable privileged mode, using the `privileged` flag on the `SecurityContext` of the container spec. This is useful for containers that want to use linux capabilities like manipulating the network stack and accessing devices. Processes within the container get almost the same privileges that are available to processes outside a container. With privileged mode, it should be easier to write network and volume plugins as separate pods that don't need to be compiled into the kubelet.
|
||||
|
||||
If the master is running Kubernetes v1.1 or higher, and the nodes are running a version lower than v1.1, then new privileged pods will be accepted by api-server, but will not be launched. They will be pending state.
|
||||
If user calls `kubectl describe pod FooPodName`, user can see the reason why the pod is in pending state. The events table in the describe command output will say:
|
||||
`Error validating pod "FooPodName"."FooPodNamespace" from api, ignoring: spec.containers[0].securityContext.privileged: forbidden '<*>(0xc2089d3248)true'`
|
||||

## Pod 容器的特权模式
|
||||
|
||||
从 Kubernetes v1.1 开始,Pod 内的任何容器都可以开启特权模式,开启的方法是在容器声明中的 `SecurityContext` 域使用 `privileged` 标志。这对于希望使用linux功能(如操作网络堆栈和访问设备)的容器非常有用。容器内的进程获得的特权与容器外的进程几乎相同。使用特权模式,将网络和卷插件编写为不需要编译到 kubelet 中的独立的 Pod 应该更容易。
|
||||
|
||||
如果主节点的 Kubernetes 版本是 v1.1 或更高,而工作节点的版本低于 v1.1,新的特权 Pod 将被 API 服务器接受,但不会被启动。它们将处于 pending 状态。如果用户使用命令 `kubectl describe pod FooPodName`,就可以看到 Pod 处于 pending 状态的原因。`describe` 命令的输出事件列表将显示:
|
||||
`Error validating pod "FooPodName"."FooPodNamespace" from api, ignoring: spec.containers[0].securityContext.privileged: forbidden '<*>(0xc2089d3248)true'`
|
||||
<!--
|
||||
Any container in a Pod can enable privileged mode, using the `privileged` flag on the [security context](/docs/tasks/configure-pod-container/security-context/) of the container spec. This is useful for containers that want to use Linux capabilities like manipulating the network stack and accessing devices. Processes within the container get almost the same privileges that are available to processes outside a container. With privileged mode, it should be easier to write network and volume plugins as separate Pods that don't need to be compiled into the kubelet.
|
||||
-->
|
||||
Pod 中的任何容器都可以使用容器规范 [security context](/docs/tasks/configure-pod-container/security-context/) 上的 `privileged` 参数启用特权模式。这对于想要使用 Linux 功能(如操纵网络堆栈和访问设备)的容器很有用。容器内的进程几乎可以获得与容器外的进程相同的特权。使用特权模式,将网络和卷插件编写为不需要编译到 kubelet 中的独立的 Pod 应该更容易。

<!--
|
||||
If the master is running a version lower than v1.1, then privileged pods cannot be created. If user attempts to create a pod, that has a privileged container, the user will get the following error:
|
||||
`The Pod "FooPodName" is invalid.
|
||||
spec.containers[0].securityContext.privileged: forbidden '<*>(0xc20b222db0)true'`
|
||||
Your container runtime must support the concept of a privileged container for this setting to be relevant.
|
||||
-->
|
||||
|
||||
如果主节点的版本低于 v1.1,那么特权 Pod 就不能被创建。如果用户尝试创建有特权容器的 Pod,将会得到下面的错误信息:
|
||||
`The Pod "FooPodName" is invalid.
|
||||
spec.containers[0].securityContext.privileged: forbidden '<*>(0xc20b222db0)true'`
|
||||
{{< note >}}
|
||||
您的容器运行时必须支持特权容器模式才能使用此设置。
