I have a Stacked master K8s cluster (etcd is also local/internal) with three master and 9 worker nodes. And my cluster version is currently 1.12.3, while going through etcd commands, i tried listing the etcd member, executing

ETCDCTL_API=3 etcdctl member list

, and found that the client Url's of master2 and master3 is wrong.

Below is the image,

As per my understanding ip for peers and client should be same, but as I can see IP is 127.0.0.1 in case of master2 and master3.

When I check the endpoint status I get below error as,

Failed to get the status of endpoint :2379 (context deadline exceeded)

while I am successfully getting the status for master1,

Could anyone please help me out in solving this.

Things I tried:

1) Edited the manifest file, etcd pods got restarted, but still nothing changed when I listed the member.

2) I have also successfully removed and added master3 in the etcd cluster, and this worked (IP's got corrected and getting the status of master3), but when I did the same for master2 getting error as

"error validating peerURLs {{ID: xyz, PeerUrls:xyz, clienturl:xyz},{&ID:xyz......}}: member count is unequal"
