Hi,

I have data of mongodb which size is 800MB in GCP VM of ubuntu.

I want to push/restore that data into running pod of GKE cluster.

In GKE cluster i deploy mongodb pod/sts/secret using this link

mongodb/mongodb-kubernetes-operator/blob/master/config/samples/mongodb.com_v1_mongodbcommunity_cr.yaml

---
apiVersion: mongodbcommunity.mongodb.com/v1
kind: MongoDBCommunity
metadata:
  name: example-mongodb
spec:
  members: 3
  type: ReplicaSet
  version: "6.0.5"
  security:
    authentication:
      modes: ["SCRAM"]
  users:
    - name: my-user
      db: admin
      passwordSecretRef: # a reference to the secret that will be used to generate the user's password
        name: my-user-password
      roles:
        - name: clusterAdmin
          db: admin

This file has been truncated. show original

if we compare above YAML and below one is same can i add volumeMounts and volumes into above given link

below is generate by Chatgpt

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mongodb-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mongodb
  template:
    metadata:
      labels:
        app: mongodb
    spec:
      containers:
      - name: mongodb
        image: mongo:latest
        volumeMounts:
        - name: mongodb-backup
          mountPath: /backup
      volumes:
      - name: mongodb-backup
        persistentVolumeClaim:
          claimName: mongodb-backup-pvc

All 3 pods are running along secrets

Im very confuse how to do it which should i use

My agenda is to have mongod running like master and slave concept i,e…, primary and secondary pod running in gke if above link is correct then im going correct way if not do send me a new link to achive.

And also i want to have storage of mongodb in gke how to do it that also tell me like using PV,PVC and storageclass

And also if i store data into new disk of GCP and add to PV,PVC will it good or not

How to achieve this please tell me steps or documentation
