7.3. Windows 容器工作负载部署示例

在有 Windows 计算节点可用后，您可以将 Windows 容器工作负载部署到集群中。

注意

这个示例部署仅供参考。

Service 对象示例

apiVersion: v1
kind: Service
metadata:
  name: win-webserver
  labels:
    app: win-webserver
spec:
  ports:
    # the port that this service should serve on
  - port: 80
    targetPort: 80
  selector:
    app: win-webserver
  type: LoadBalancer

apiVersion: v1
kind: Service
metadata:
  name: win-webserver
  labels:
    app: win-webserver
spec:
  ports:
    # the port that this service should serve on
  - port: 80
    targetPort: 80
  selector:
    app: win-webserver
  type: LoadBalancer

1

指定要使用的容器镜像：mcr.microsoft.com/powershell:<tag> 或 mcr.microsoft.com/windows/servercore:<tag>。容器镜像必须与节点上运行的 Windows 版本匹配。

对于 Windows 2019，使用 ltsc2019 标签。
对于 Windows 2022，使用 ltsc2022 标签。

2

指定要在容器上执行的命令。

对于 mcr.microsoft.com/powershell:<tag> 容器镜像，您必须将命令定义为 pwsh.exe。
对于 mcr.microsoft.com/windows/servercore:<tag> 容器镜像，您必须将该命令定义为 powershell.exe。

3

指定您为集群中的 Windows 操作系统变体创建的运行时类。
