Kubernetes Helm PVC

Question

我有一个yml文件，在我的提供商上创建一个pvc (数字海洋)

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: test-pvc
  namespace: test
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: do-block-storage

我也在使用头盔图表，并希望能够指向已经创建的pvc，我如何才能做到这一点？此舵图是在PVC创建/部署之后部署的。

  master:
    persistence:
      enabled: true
      ## mariadb data Persistent Volume Storage Class
      ## If defined, storageClassName: <storageClass>
      ## If set to "-", storageClassName: "", which disables dynamic provisioning
      ## If undefined (the default) or set to null, no storageClassName spec is
      ##   set, choosing the default provisioner.  (gp2 on AWS, standard on
      ##   GKE, AWS & OpenStack)
      ##
      # storageClass: "-"
      accessMode: ReadWriteOnce
      size: 10Gi

若要将PVC安装在掌舵图中，请执行以下操作：

• 在舵机图表中禁用持久性卷创建

master:
    persistence:
      enabled: false #Setting it to false

• 修改部署yaml，它位于舵图的“模板”文件夹中。点上你的Pod来安装你自己的PVC。

就像这样：

apiVersion: v1
kind: Pod
metadata:
  name: task-pv-pod
spec:
  volumes:
    - name: task-pv-storage
      persistentVolumeClaim:
        claimName: test-pvc  # pointing to existing test-pvc
  containers:
    - name: task-pv-container
      image: nginx
      ports:
        - containerPort: 80
          name: "http-server"
      volumeMounts:
        - mountPath: "/usr/share/nginx/html"
          name: task-pv-storage

更新：

特别是在您的情况下，您可以在existingClaim参数中values.yaml中指定pvc名称，它将是从你的部署中获得。
