存储persistent不用sc不行嘛

[barrettzjh]

下面是我的yaml
apiVersion: redis.kun/v1beta1
kind: RedisCluster
metadata:
name: test
annotations:
redis.kun/scope: "cluster-scoped"
namespace: default
spec:
image: redis:5.0.4-alpine
resources:
limits:
cpu: 400m
memory: 300Mi
requests:
cpu: 50m
memory: 30Mi
size: 3
storage:
persistentVolumeClaim:
claimName: redis-data-claim

这种固定pvc的格式可以用嘛，应该如何写呢，感谢
