/cc Since it is related to the metrics server. the metrics server keeps dying as the log shown in I cannot get more logs of metrics servers from the CI artifacts. Currently, we are using metric server 0.4.4 and the latest 0.5.0 is released. Are there some known bugs that may be related to this test failure?
I don't think so. /cc
The metrics-server fails to bind ~because there is another process listening~ on port 443 are some of the konnectivity pods listening on the port :443?
In the dockerfile of metrics-server if has ? Maybe it has permission problem?
ahh, right, nice catch, I didn't pay attention to the error and blindly assumed collision :sweat_smile: ... who can take an action on that? has this changed recently?
If the metrics-server version used after , I think it is correct. has no change recently.

I vaguely remember some changes recently to reduce privileges on pods on CI, tthis seems likely a permission problem, does this ring a bell? EDIT This PR introduced the change , any special reason why we want to run it in a privileged port if this is accessed using a Service? EDIT 2 let see if this is the problem
Yeah, Maybe you can refer to this, the release notes about v0.4.4 metrics-server . I think you have resolved this problem.
Release v0.3.X was already using privileged port 443, as v0.4.X has migrated to distroless image we needed to introduce to give it needed privileges. What's weird for me is that the test is flaking and not failing. Could it be related to node where MS is scheduled?
You mean, there may be other reasons? If so, may require in-depth analysis.
As far as I can tell, is never starting properly, even when the jobs are successful. If we were to take this job, that has succeeded: From the serial logs, we can see that the metrics-server pod is crash looping: But from the build logs, we can see that at some point the pod was deemed ready: To me it seems that there are 2 issues, one being that metrics-server doesn't have the capabilities it needs to run and another one that still needs to be investigated where metrics-server is sometimes marked ready even though it is in a crash looping state.
This is a problem with the metrics-server deployment on the CI jobs and the metrics tests I don't know which sig owns these components but it will be better to find first an owner, what is is clear is that the metrics tests are not reliable since once you set a readiness probe on the metrics-server it fails consistently , , however the tests pass cc
it seems the last try was the good one :smile:
