k8s version: v1.12.2
operator: v1.1.8
tidb version: v4.0.2
查看了operator-controller日志，pd日志和discovery日志，一步步定位，但是还是不太清楚哪里哪里不对，麻烦看下，谢谢！

我这边登录discovery的pod，执行
]# kubectl exec -it -n gejb-test test-001-01-discovery-5d9c476d87-hzxtw -- /bin/sh
/ # nc -nvv 10.233.0.1:443

k8s的service信息

是不是哪里配置的不对，导致实例创建卡住了。
