您可以在ACK Window容器上使用云盘存储资源。本文介绍如何在Windows容器上使用云盘。

操作步骤

  1. 使用以下模板在集群中部署flexvolume组件。

    FlexVolume是Kubernetes支持的一种存储插件扩展方式。详情请参见存储插件说明。

          env:

          volumeMounts:

  2. 使用以下YAML定义的PVC和Deployment验证存储组件是否可用。 
    kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc-disk
spec:
  accessModes:
    - ReadWriteOnce
  storageClassName: alicloud-disk-ssd-windows
  resources:
    requests:
      storage: 20Gi

apiVersion: apps/v1
kind: Deployment
metadata:
  name: dynamic-create
  labels:
    app: nginx
spec:
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      nodeSelector:
        beta.kubernetes.io/os: windows
      tolerations:
      - key: "os"
        operator: "Equal"
        value: "windows"
        effect: "NoSchedule"
      containers:
      - name: nginx
        image: registry.cn-hangzhou.aliyuncs.com/acs/flexvolume:1.11.2.2af33e7-windows1809
        command: ["pwsh.exe"]
        args: ["-Command", "start-sleep 1000"]
        volumeMounts:
          - name: disk-pvc
            mountPath: 'C:\data'
      volumes:
        - name: disk-pvc
          persistentVolumeClaim:
            claimName: pvc-disk
    如果存储组件成功部署，执行命令kubectl get pv看到自动创建的PV。 
    $ kubectl get pv
