设置GCP FileStorage和Kubernetes

Question

如何在GCP中将FileStorage挂载到Kubernetes pod

我确实遵循了文档，但pod仍然悬而未决

我做到了：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: <some name>
spec:
  capacity:
    storage: 50Gi
  accessModes:
  - ReadWriteMany
  nfs:
    path: /
    server: <filestorage_ip with this format xx.xxx.xxx.xx>

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: <some name>
  namespace: <some name>
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: ""
  resources:
    requests:
      storage: 50Gi

apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: <some name>
  name: <some name>
  labels:
    app: <some name>
spec:
  replicas: 2
  selector:
    matchLabels:
      app: <some name>
  template:
    metadata:
      labels:
        app: <some name>
    spec:
      containers:
      - name: <some name>
        image: gcr.io/somepath/<some name>@sha256:<some hash>
        ports:
        - containerPort: 80 
        volumeMounts:
          - name: <some name>
            mountPath: /var/www/html
        imagePullPolicy: Always
      restartPolicy: Always
      volumes:
        - name: <some name>
          persistentVolumeClaim:
            claimName: <some name>
            readOnly: false

运行kubectl -n <some name> describe pods返回：

pod似乎无法访问FileStorage服务的IP，文档中说需要在同一个VPC上

“授权网络* Filestore实例只能从授权VPC网络中的机器访问。请选择您需要访问的网络。”

但是我不知道如何将Kubernetes集群添加到VPC中

有什么建议吗？

我发现了问题

PersistentVolume不能挂载在path: /中，它需要“文件共享属性”字段，让你在创建时填写，现在可以使用多个pods！
