Question: What is Configure RunAsUserName for Windows pods and containers?

Answer: Configure RunAsUserName for Windows pods and containersFEATURE STATE: Kubernetes v1.18 [stable]This page shows how to use the runAsUserName setting for Pods and containers that will run on Windows nodes. This is roughly equivalent of the Linux-specific runAsUser setting, allowing you to run applications in a container as a different username than the default.Before you beginYou 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.Set the Username for a PodTo specify the username with which to execute the Pod's container processes, include the securityContext field (PodSecurityContext) in the Pod specification, and within it, the windowsOptions (WindowsSecurityContextOptions) field containing the runAsUserName field.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:windows/run-as-username-pod.yaml apiVersion: v1 kind: Pod metadata: name: run-as-username-pod-demo spec: securityContext: windowsOptions: runAsUserName: "ContainerUser" containers: - name: run-as-username-demo image: mcr.microsoft.com/windows/servercore:ltsc2019 command: ["ping", "-t", "localhost"] nodeSelector: kubernetes.io/os: windows Create the Pod:kubectl apply -f https://k8s.io/examples/windows/run-as-username-pod.yaml Verify that the Pod's Container is running:kubectl get pod run-as-username-pod-demo Get a shell to the running Container:kubectl exec -it run-as-username-pod-demo -- powershell Check that the shell is running user the correct username:echo $env:USERNAME The output should be:ContainerUser Set the Username for a ContainerTo specify the username with which to execute a Container's processes, include the securityContext field (SecurityContext) in the Container manifest, and within it, the windowsOptions (WindowsSecurityContextOptions) 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.Here is the configuration file for a Pod that has one Container, and the runAsUserName field is set at the Pod level and the Container level:windows/run-as-username-container.yaml apiVersion: v1 kind: Pod metadata: name: run-as-username-container-demo spec: securityContext: windowsOptions: runAsUserName: "ContainerUser" containers: - name: run-as-username-demo image: mcr.microsoft.com/windows/servercore:ltsc2019 command: ["ping", "-t", "localhost"] securityContext: windowsOptions: runAsUserName: "ContainerAdministrator" nodeSelector: kubernetes.io/os: windows Create the Pod:kubectl apply -f https://k8s.io/examples/windows/run-as-username-container.yaml Verify that the Pod's Container is running:kube
