[Bug]: KafkaUser object doesn't produce a new certificate after the kafka cluster is destroyed and redeployed #10798

Open varunreddyj opened 3 weeks ago

varunreddyj commented 3 weeks ago

Bug Description

once the strimzi kafka operator is deployed, we are deployed kafka cluster, we are deplying KafkaUser from our application manifest which in turn will create secrets with certs. But when we delete the kafka cluster and redeploy it , KafkaUser object doesn't produce a new certificate and hence causing SSL Handshake issues when our application is trying to communicate with kafka cluster .

Steps to reproduce

  1. Deploy strimzi operator
  2. Deploy Kafka cluster
  3. create KafkaUser object which will create secrets with certs to communicate with kafka cluster
  4. delete kafka cluster
  5. Re-deploy kafka cluster
  6. existing kafkauser wont be able to communicate with new kafka because KafkaUser object doesn't produce a new certificate after the kafka cluster is destroyed and redeployed.

Expected behavior

KafkaUser object should produce a new certificate after the kafka cluster is destroyed and redeployed

Hi, could you please attach logs from the User Operator? Also, in what state is the KafkaUser CR?

scholzj commented 3 weeks ago

I think this needs to have all custom resources provided and the full logs from all components as well. Not just from user operator and the Kafka CR.

Triaged on 14.11.2024: @varunreddyj could you please attach the logs and YAMLs of the CRs, so we can have a look at it? Thanks

FYI: I tries to reproduce this, but without success. So unless more information is provided, we should close it.
