现有k8s集群+harbor离线部署kubesphere 3.1.1 Redis-ha-server启动失败的处理办法

kasse

部署完毕后，出现 kubesphere-system redis-ha-server-0 0/2 Init:CrashLoopBackOff；
kubectl -n kubesphere-system logs redis-ha-server-0 config-init #查看pod日志，提示mkdir: can’t create directory ‘/data/conf/’: Permission denied，无权限写入PVC
kubectl get pvc -n kubesphere-system #获取PVC正常
kubectl get -n kubesphere-system pods redis-ha-server-0 -o yaml #查找资料建议修改securityContext:
fsGroup: 1000 #改为0

runAsNonRoot: true #改为false

runAsUser: 1000 #改为0
5.kubectl edit -n kubesphere-system pods redis-ha-server-0 -o yaml #直接修改，发现无法保存
6.kubectl describe pods redis-ha-server-0 -n kubesphere-system #查看pod信息，发现Controlled By: StatefulSet/redis-ha-server，此POD为 statefulset控制
7.kubectl get statefulsets.apps -n kubesphere-system #发现redis-ha-server
8.kubectl edit statefulsets.apps -n kubesphere-system redis-ha-server -o yaml直接编辑更改securityContext ，0，false，0，保存侯问题解决，pod正常启动

###说实话，刚刚接触kubesphere，此问题定位也早就找到，但是确定statefulsets管理此POD，费了不少功夫，一方面k8s的理论知识没时间深入看，另一方面kubesephere 能不能提供一些详细部署配置问题…

报这个错你有做什么操作吗，另外你的k8s存储卷是类型的；我报这个错是因为手动把该glusterfs存储卷从单副本改成了双副本

# kubectl -n kubesphere-system logs redis-ha-server-0 config-init
Could not connect to Redis at redis-ha:26379: Name does not resolve
mkdir: can't create directory '/data/conf/': Permission denied
