操作场景

云硬盘创建或导入CCE后，可以在工作负载中挂载云硬盘。

须知：

云硬盘不支持跨可用区挂载。在挂载前，您可以使用** kubectl get pvc** 命令查询当前集群所在分区下可用PVC。

操作步骤

步骤 1 执行如下命令，配置名为“evs-pod-example.yaml”的创建Pod的yaml文件。

touch evs-pod-example.yaml

vi evs-pod-example.yaml

在无状态工作负载中基于pvc共享式使用云硬盘存储示例：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: evs-pod-example
namespace: default
spec:
replicas: 1
selector:
matchLabels:
app: evs-pod-example
template:
metadata:
labels:
app: evs-pod-example
spec:
containers:

• image: nginx** **
  name: container-0
  volumeMounts:
• mountPath: /tmp
  name: pvc-evs-example
  restartPolicy: Always
  volumes:
• name: pvc-evs-example
  persistentVolumeClaim:
  claimName: pvc-evs-auto-example

表 关键参数说明

“spec.template.spec.containers.volumeMounts.name ”和 “spec.template.spec.volumes.name”有映射关系，必须保持一致。

在有状态工作负载中基于PVCTemplate独占式使用云硬盘存储示例：

步骤 2 执行如下命令创建Pod。

kubectl create -f evs-pod-example.yaml

创建完成后，登录CCE控制台，在左侧导航栏中选择“存储管理 > 云硬盘存储卷”。单击PVC名称，在PVC详情页面可查看云硬盘和PVC的绑定关系。
