Description

What would you like to be added

In our CI we do some basics tests of the cluster after a kubespray runs, to validate we did built it correctly.

We should replace it with dedicated tester of Kubernetes functionality, which are already used by others, such as hydrophone : https://github.com/kubernetes-sigs/hydrophone/ We'll need to select a subset of tests, because we want to keep the runtime relatively low (I'd say max 10 minutes for the testsuite, considering our CI jobs are currently < 15 min each, I think).

This would need roughly here : https://github.com/kubernetes-sigs/kubespray/blob/1c008d79b1b617296b0d5427344192adc7403ace/tests/scripts/testcases_run.sh#L82-L87

(and also probably some stuff in the docker image, we want to download / built hydrophone here, not exactly sure how to do that).

Why is this needed

  1. Less maintenance for us
  2. More alignment with the wider ecosystem

Research direction
The task involves replacing netchecker and manual tests with hydrophone (https://github.com/kubernetes sigs/hydrophone/) in the kubespray CI. Start by examining tests/scripts/testcases run.sh lines 82-87 to understand the current test setup. Investigate how to build/install hydrophone in the CI Docker image, then select a subset of Kubernetes e2e conformance tests that run within 10 minutes. Refer to the slack thread (https://kubernetes.slack.com/archives/C78F00H99/p1763150495755689) for additional context and suggestions.
