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. 部署插件。
    1. 创建YAML文件。

      使用以下模板创建YAML文件在集群中部署Flexvolume组件，创建Windows环境下的StorageClass，以及更新集群中默认安装的alicloud-disk-controller，使其支持Windows云盘PV的创建。

      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。

    2. 执行kubectl apply -f <YAML文件名称>.yaml部署插件。
  2. 创建应用。
    1. 使用以下YAML模板创建PVC和StatefulSet验证存储组件是否可用。
      apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    app: nginx
spec:
  ports:
  - port: 80
    name: web
  clusterIP: None
  selector:
    app: nginx
---
apiVersion: apps/v1beta2
kind: StatefulSet
metadata:
  name: disk-windows
spec:
  selector:
    matchLabels:
      app: nginx
  serviceName: "nginx"
  replicas: 1
  template:
    metadata:
      labels:
        app: nginx
    spec:
      tolerations:
      - effect: NoSchedule
        key: os
        operator: Equal
        value: windows
      containers:
      - name: nginx
        image: registry.cn-hangzhou.aliyuncs.com/acs/flexvolume:v1.16.9.7be0fa0-windows1809
        command: ["pwsh.exe"]
        args: ["-Command", "start-sleep 10000"]
        volumeMounts:
          - name: disk-essd
            mountPath: "C:\\data"
  volumeClaimTemplates:
  - metadata:
      name: disk-essd
    spec:
      accessModes: [ "ReadWriteOnce" ]
      storageClassName: alicloud-disk-essd-windows
      resources:
        requests:
          storage: 20Gi
    如果存储组件成功部署，执行命令kubectl get pv会看到自动创建的PV。
    返回结果如下：
