kind: StorageClass

metadata:

  name: mongodb-data

  namespace: kube-yapi

provisioner: fuseim.pri/ifs

            mountPath: /data/db

      volumes:

      - name: datadb

        persistentVolumeClaim:

          claimName: mongodb-pvc

kubectl create -f mongodb.yaml

创建用户

kubectl exec -it mongo-0 /bin/bash -n kube-yapi

use admin

db.createUser({user:"admin",pwd:"password",roles:["root"]})

use yapi

db.createUser({user: "yapi", pwd: "yapi123", roles: [{ role: "dbOwner", db: "yapi" }]})
