在 Okteto Cloud 上创建 PersistentVolume答案

【问题标题】：Creating a PersistentVolume on Okteto Cloud在 Okteto Cloud 上创建 PersistentVolume

【问题描述】：

当我尝试使用以下定义在 Okteto Cloud 上创建持久卷时：

kind: PersistentVolume
apiVersion: v1
metadata:
  name: postgres-pv
  labels:
    type: local
    app: postgres
spec:
  storageClassName: manual
  capacity:
    storage: 5Gi
  accessModes:
    - ReadWriteMany
  hostPath:
    path: "/mnt/data"

我收到以下错误：

Error from server (Forbidden): error when retrieving current configuration of:
Resource: "/v1, Resource=persistentvolumes", GroupVersionKind: "/v1, Kind=PersistentVolume"
Name: "postgres-pv", Namespace: ""
Object: &{map["apiVersion":"v1" "kind":"PersistentVolume" "metadata":map["annotations":map["kubectl.kubernetes.io/last-applied-configuration":""] "labels":map["app":"postgres" "type":"local"] "name":"postgres-pv"] "spec":map["accessModes":["ReadWriteMany"] "capacity":map["storage":"5Gi"] "hostPath":map["path":"/mnt/data"]]]}
from server for: "deploy/k8s.postgres.yml": persistentvolumes "postgres-pv" is forbidden: User "system:serviceaccount:okteto:07e6fdbf-55c2-4642-81e3-051e8309000f" cannot get resource "persistentvolumes" in API group "" at the cluster scope

但是根据the Okteto cloud docs，persistentVolumes 似乎已获得授权。

我将如何在那里创建一个？

对于上下文，我正在尝试重现一个简单的 postgres 部署（没有复制，没有备份）。这是我的完整部署文件：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: postgres
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: postgres
    spec:
      containers:
        - name: postgres
          image: postgres:10.4
          imagePullPolicy: "IfNotPresent"
          ports:
            - containerPort: 5432
          envFrom:
            - configMapRef:
                name: postgres-config
          volumeMounts:
            - mountPath: /var/lib/postgresql/data
              name: postgredb
      volumes:
        - name: postgredb
          persistentVolumeClaim:
            claimName: postgres-pv-claim

apiVersion: v1

kind: PersistentVolumeClaim

【解决方案1】：

持久卷是集群范围的资源，并且是不允许的。文档有误，谢谢指出。

您可以改为使用默认存储类创建 PersistentVolumeClaims（并删除持久卷清单）：

  apiVersion: v1
  kind: PersistentVolumeClaim
  metadata:
    name: postgres-pv-claim
  spec:
    accessModes:
    - ReadWriteOnce
    resources:
      requests:
        storage: 10Gi

希望对你有帮助:-)

效果很好，谢谢！我想你的意思是“不允许”？
