错误“没有可用于此声明的持久卷且未设置存储类别”

Question

是否需要在节点中手动创建目录还是由 pv 自动创建？

这是我的 pv & pvc 文件，我看到了这个错误

没有可用于此声明的持久卷，也没有设置存储类

如何解决这个问题？

Answer 1

storageClassName: manual您忘记在 中指定PersistentVolumeClaim。

Answer 2

回到你的主要问题

是否需要在节点中手动创建目录还是由 pv 自动创建？

首先，输出中的错误与您的问题无关。作为您问题的答案 - 是的。它由PV自动装箱。

为了做到这一点，首先你必须StorageClass用no-provisioner下面的例子来创建

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: manual
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer

然后你必须PersistentVolume通过定义这个storageClassName和hostPath参数来创建，如下所示：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: zk1-pv
spec:
  storageClassName: manual
  capacity:
    storage: 1Gi
  accessModes:
  - ReadWriteOnce
  hostPath:
    path: /mr/zk

然后你必须创建 PVC 和 Pod/Deployment 作为下面的例子：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: myclaim
spec:
  storageClassName: manual
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

---
apiVersion: v1
kind: Pod
metadata:
  name: mypod
spec:
  containers:
    - name: containerName
      image: gcr.io/google-containers/nginx:1.7.9
      volumeMounts:
      - mountPath: "/var/www/html"
        name: mypd
  volumes:
    - name: mypd
      persistentVolumeClaim:
        claimName: myclaim

注意：
不要忘记storageClassName: manualPVC 和 PV 清单上的put参数。否则他们将无法相互绑定。

希望它清除
