How to specify the naming format of PVCs when using Statefulset in Kubernetes?

The following is the Statefulset yaml.

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: mongodb
spec:
  serviceName: mongo
  replicas: 3
  selector:
    matchLabels:
      app: mongo

( skip )

  volumeClaimTemplates:
    - metadata:
        name: data-volume
      spec:
        accessModes: [ "ReadWriteOnce" ]
        resources:
          requests:
            storage: 10Gi

Due to the use of the volumeClaimTemplates, the PVC name must be:

data-volume-mongodb-0
data-volume-mongodb-1
data-volume-mongodb-2

However, the action of creating PVCs is not within my control. The PVC naming format provided by the other party is as follows:

mongodb-0-pvc
mongodb-1-pvc
mongodb-2-pvc

Therefore, I need to follow their naming format while continuing to use the volumeClaimTemplates. How should I modify it?

Solution

  • Thanks for everyone's comments. The PVCs name can only end with the ordinal, so no changing is needed.
