Mount Alibaba Cloud disks to containers that run Windows

Procedure

1. Use the following template to deploy the Flexvolume plug-in in a cluster.

   FlexVolume is a storage plug-in supported by Kubernetes. For more information, see Volume plug-ins.

2. To verify that Flexvolume is deployed, use the following YAML file to create a persistent volume claim (PVC) and a Deployment.

   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

   Run the kubectl get pv command to check whether the PV is automatically created.

   $ kubectl get pv
