Question: Document leader election usage #116

Open fcoeguiguren opened 1 year ago

fcoeguiguren commented 1 year ago

I noted that there is some leader election flag and logic in the source code, but it is not clear to me on how and why is there.

Could you please update the docs?

Thanks

Workaround:

Please use Bitnami Chart which is comprehensive.

... but it is not clear to me on how and why is there.

We discovered, that when we not using leaderElection (leaderElection: {}) AND we have N replicas, we getting the Kubernetes events from all the replicas. I mean, it duplicating events.

If we using the leaderElection:

leaderElection:
  enabled: true
  leaderElectionID: {{ LeaderElectionID }}

AND N replicas, we getting only one event record. Looks like another instances are just waiting, when leader is lost and take his role (follower -> leader), I guess.

Official documentation will be better, like guessing :).
