Describe the bug (actual behavior)
Hi I have installed kafka-ui v1.4.1 and I am trying to create multiple clusters. If one of my cluster has a bad config, for example a bad password both clusters fails and the one that is correctly set up never becomes green. Is this a known issue ? how can I fix this ? And yes I can make sure that a password is never wrong and what not ... but passwords can expire i'd like to avoid it crashing because of one bad cluster in my production.
Expected behavior
Kakfa-ui runs and only the cluster with the bad config is not ready
Your installation details
- v1.4.1
- helm latest one
- two cluster configured via configmap
- Running on eks 1.31
Steps to reproduce
just configure two cluster, one of which has some bad config, bad bootstrap url or password
