kubectl create for persistent storage 报错

Question

我正在尝试为 couch DB 部署持久存储，但失败并出现错误

kubectl create -f couch_persistant_deploy.yaml

error: error validating "couch_persistant_deploy.yaml": error validating data: couldn't find type: v1.Deployment; if you choose to ignore these errors, turn validation off with --validate=false

创建volume.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: task-pv-volume
  labels:
    type: local
spec:
  storageClassName: manual
  capacity:
    storage: 2Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: /mnt/sda1/data/test

领取volume.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: task-pv-claim
  labels:
    app: couchdb
spec:
  storageClassName: manual
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

部署 VM.yaml

apiVersion: extensions/v1beta1
#apiVersion: v1
kind: Deployment
#kind: ReplicationController
metadata:
  name: couchdb
spec:
  replicas: 1
  template:
    metadata:

    spec:
      containers:

          image: "couchdb"
          imagePullPolicy: Always
          env:
          - name: COUCHDB_USER
            value: admin
          - name: COUCHDB_PASSWORD
            value: password
          ports:
          - name: couchdb
            containerPort: 5984
          - name: epmd
            containerPort: 4369
            containerPort: 9100
          volumeMounts:
          - mountPath: "/opt/couchdb/data"
            name: task-pv-storage
      imagePullSecrets:
      - name: registrypullsecret2
      #volumes:
        #- name: database-storage
        #  emptyDir: {}
      volumes:
      - name: task-pv-storage
        persistentVolumeClaim:
        claimName: task-pv-claim

非常感谢任何潜在客户。

你的错误信息应该是这样的：

error: error validating "couch_persistant_deploy.yaml": error validating data: ValidationError(Deployment.spec.template.spec.volumes[0]): unknown field "claimName" in io.k8s.api.core.v1.Volume; if you choose to ignore these errors, turn validation off with --validate=false

看，具体报错信息：unknown field "claimName" in io.k8s.api.core.v1.Volume

您需要将 claimName 放在 persistentVolumeClaim 下。

  volumes:
  - name: task-pv-storage
    persistentVolumeClaim:
      claimName: task-pv-claim  # fix is here

但你做到了

  volumes:
  - name: task-pv-storage
    persistentVolumeClaim:
    claimName: task-pv-claim  # invalid

这会使您的 Deployment 对象无效
