Kubernetes PersistentVolume issues in GCP ( Deployment stuck in pending )-CodePudding

Hi i'm trying to create a persistent volume for my mongoDB on kubernetes on google cloud platform and i'm stuck in pending

Here you have my manifest :

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: account-mongo-depl
  labels:
    app: account-mongo
spec:
  replicas: 1
  serviceName: 'account-mongo'
  selector:
    matchLabels:
      app: account-mongo
  template:
    metadata:
      labels:
        app: account-mongo
    spec:
      volumes:
        - name: account-mongo-storage
          persistentVolumeClaim:
            claimName: account-db-bs-claim
      containers:
        - name: account-mongo
          image: mongo
          volumeMounts:
            - mountPath: '/data/db'
              name: account-mongo-storage
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: account-db-bs-claim
spec:
  storageClassName: do-block-storage
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

---
apiVersion: v1
kind: Service
metadata:
  name: account-mongo-srv
spec:
  type: ClusterIP
  selector:
    app: account-mongo
  ports:
    - name: account-db
      protocol: TCP
      port: 27017
      targetPort: 27017

Here you have my list of pods

My pods is stuck in pending until fail

CodePudding user response：

If you're on GKE, you should already have dynamic provisioning setup.

  storageClassName: do-block-storage
  accessModes:
    - ReadWriteOnce

"do-block-storage"? Were you running on Digital Ocean previously? You should be able remove the storageClassName line and use the default provisioner Google provides.

For example, here's a snippet from one of my own statefulsets

  volumeClaimTemplates:
  - metadata:
      name: data
    spec:
      accessModes: [ "ReadWriteOnce" ]
      ## Specify storage class to use nfs (requires nfs provisioner. Leave unset for dynamic provisioning)
      #storageClassName: "nfs"
      resources:
        requests:
          storage: 10G

I do not specify a storage class here, so it uses the default one, which provisions as a persistent disk on GCP

$ kubectl get storageclass
NAME                 PROVISIONER            RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
