On GKE, I set a statefulset resource as
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: redis
spec:
serviceName: "redis"
selector:
matchLabels:
app: redis
updateStrategy:
type: RollingUpdate
replicas: 3
template:
metadata:
labels:
app: redis
spec:
containers:
- name: redis
image: redis
resources:
limits:
memory: 2Gi
ports:
- containerPort: 6379
volumeMounts:
- name: redis-data
mountPath: /usr/share/redis
volumes:
- name: redis-data
persistentVolumeClaim:
claimName: redis-data-pvc
Want to use pvc so created this one. (This step was did before the statefulset deployment)
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: redis-data-pvc
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 10Gi
When check the resource in kubernetes
kubectl get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
redis-data-pvc Bound pvc-6163d1f8-fb3d-44ac-a91f-edef1452b3b9 10Gi RWO standard 132m
The default Storage Class is standard
.
kubectl get storageclass
NAME PROVISIONER
standard (default) kubernetes.io/gce-pd
But when check the statafulset’s deployment status. It always wrong.
# Describe its pod details

Why can’t it find the redis-data-pvc
name?
