Follower cannot connect to master because of bad IP

[astingengo]

Describe your question
I'm having a redis cluster (size: 3) and everything looks good except one follower (the other two are connecting to leaders correctly)
One follower is trying to connect to an unexisting leader IP.

20 Dec 2024 09:27:35.882 * Connecting to MASTER 10.42.2.147:6379                                                                                                                                                                                                                                                                                      │

20 Dec 2024 09:27:38.692 # Error condition on socket for SYNC: Host is unreachable 

the problem is that my leader not connected with a follower IP is not 10.42.2.147 (I don't have that IP on any leader actually)

What version of redis-operator are you using?
redis-operator version: 0.18.1

Additional context
redis version: 7.0.12

A valid issue, I’m facing the same

[astingengo]

So I think I know how to reproduce this.

1. Have redis operator on version: 0.18.0
2. Upgrade to 0.18.1
3. Delete all redis pods and allow them to redeploy
4. Check logs and you should see the errors

I completely removed the redis and redeploy it with operator 0.18.1 and can't reproduce the error now (but is not an upgrade from 0.18.0 is a fresh install of 0.18.1)
