+This page shows how to enable and use the `RunAsUserName` feature for pods and containers that will run on Windows nodes. This feature is meant to be the Windows equivalent of the Linux-specific `runAsUser` feature, allowing users to run the container entrypoints with a different username that their default ones.
+-->
+
+本页展示如何为运行在 Windows 节点上的 pod 和容器启用并使用 `RunAsUserName` 功能。此功能旨在成为 Windows 版的 `runAsUser`（Linux），允许用户使用与默认用户名不同的用户名运行容器 entrypoint。

+{{< note >}}
+<!--
+This feature is in beta. The overall functionality for `RunAsUserName` will not change, but there may be some changes regarding the username validation.
+-->
+该功能目前处于 beta 状态。 `RunAsUserName` 的整体功能不会出现变更，但是关于用户名验证的部分可能会有所更改。

+You need to have a Kubernetes cluster and the kubectl command-line tool must be configured to communicate with your cluster. The cluster is expected to have Windows worker nodes where pods with containers running Windows workloads will get scheduled.

+
+你必须有一个 Kubernetes 集群，并且 kubectl 必须能和集群通信。集群应该要有 Windows 工作节点，将在其中调度运行 Windows 工作负载的 pod 和容器。

+## Set the Username for a Pod
+
+To specify the username with which to execute the Pod's container processes, include the `securityContext` field ([PodSecurityContext](/docs/reference/generated/kubernetes-api/{{< param "version" >}}/#podsecuritycontext-v1-core) in the Pod specification, and within it, the `windowsOptions` ([WindowsSecurityContextOptions](/docs/reference/generated/kubernetes-api/{{< param "version" >}}/#windowssecuritycontextoptions-v1-core) field containing the `runAsUserName` field.

+
+## 为 Pod 设置 Username
+
+要指定运行 Pod 容器时所使用的用户名，请在 Pod 声明中包含 `securityContext` （[PodSecurityContext](/docs/reference/generated/kubernetes-api/{{< param "version" >}}/#podsecuritycontext-v1-core)）字段，并在其内部包含 `windowsOptions` （[WindowsSecurityContextOptions](/docs/reference/generated/kubernetes-api/{{< param "version" >}}/#windowssecuritycontextoptions-v1-core)）字段的 `runAsUserName` 字段。

+The Windows security context options that you specify for a Pod apply to all Containers and init Containers in the Pod.

+Here is a configuration file for a Windows Pod that has the `runAsUserName` field set:

+
+您为 Pod 指定的 Windows SecurityContext 选项适用于该 Pod 中（包括 init 容器）的所有容器。

+
+<!--
+Create the Pod:

+
+创建 Pod：
+
+```shell
+kubectl apply -f https://k8s.io/examples/windows/run-as-username-pod.yaml
+```

+<!--
+Verify that the Pod's Container is running:
+-->
+
+验证 Pod 容器是否在运行：
+
+```shell
+kubectl get pod run-as-username-pod-demo
+```
+
+<!--
+Get a shell to the running Container:

+
+获取该容器的 shell：
+
+```shell

+检查运行 shell 的用户的用户名是否正确：

+## Set the Username for a Container

+To specify the username with which to execute a Container's processes, include the `securityContext` field ([SecurityContext](/docs/reference/generated/kubernetes-api/{{< param "version" >}}/#securitycontext-v1-core)) in the Container manifest, and within it, the `windowsOptions` ([WindowsSecurityContextOptions](/docs/reference/generated/kubernetes-api/{{< param "version" >}}/#windowssecuritycontextoptions-v1-core) field containing the `runAsUserName` field.

+<!--
+The Windows security context options that you specify for a Container apply only to that individual Container, and they override the settings made at the Pod level.

+
+您为容器指定的 Windows SecurityContext 选项仅适用于该容器，并且它会覆盖 Pod 级别设置。

+{{< codenew file="windows/run-as-username-container.yaml" >}}

+## Windows Username limitations
