[Bug] Incorrectly configured STRIMZI_KUBERNETES_VERSION makes the operator stuck

[scholzj]

If you configure the STRIMZI_KUBERNETES_VERSION environment variable in the CO to something that is not a map (e.g. set it to STRIMZI_KUBERNETES_VERSION=1.33.0 instead of a valid map such as STRIMZI_KUBERNETES_VERSION="major=1, minor=33"), it will fail to parse the map and get an exception which is not handled. But because the futures are not failed properly, it remains stuck in a running state without terminating forever.

The full log from the CO is here:

2025-04-26 20:19:44 INFO  ShutdownHook:35 - Shutdown hook started
2025-04-26 20:19:44 INFO  LeaderElectionManager:82 - Stopping the Leader Elector

The same seems to happen when we catch the ParseException in the code. We do not fail the future either when we catch it, so it if fails to parse the date (which is what throws it - STRIMZI_KUBERNETES_VERSION="major=1, minor=33, buildDate=not-a-build-date") it remains also stuck and never terminates.

But it does start the shutdown hook regardless the future not being failed. So I'm not sure it is as simple as failing the future. The problem might be that the shutdown hook gets stuck when things fail too early?

As last log is about the leader elector, could it be something related to it which is not able to stop properly for any reasons? Just guessing.

I don't really know. It seems to get stuck in the shutdown, so seemingly unrelated to the version decoding. But that said, I did not observed it when the Kube client failed to decode the version. Only in the branch where we fail decode the version from the environment variable :-/

Triaged on 29.5.2025: We should investigate where the operator gets stuck and we should fix it.

I just got this on k3s, after setting extraEnv operator was able to start: STRIMZI_KUBERNETES_VERSION="major=1, minor=33
