【TiDB 版本】：
v4.0.8 -
【k8s版本】
v1.19.3 -
【问题描述】：
根据k8s部署文档中的示例https://github.com/pingcap/tidb-operator/blob/master/examples/tiflash/tidb-cluster.yaml部署，只将名字改成了k8s-staging-local-pv-test，apply后未启动任何pod -
【具体流程】
在此之前，k8s集群中配置了一共三个节点
[root@{master-node} ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
{master-node} Ready master 4d15h v1.19.3
{follower-node-1} Ready 4d15h v1.19.3
{follower-node-2} Ready 2d15h v1.19.4
集群使用local pv持久化
[root@{master-node} ~]# kubectl get pods --all-namespaces

TiDB Operator的设置参考了示例文档

使用apply后，未生成任何新的pod
