Yes, that's right.
Also, we need to upgrade Golang version to v1.22 due to kubernetes/autoscaler@eb5d875.

go: downloading k8s.io/autoscaler/cluster-autoscaler v0.0.0-20240320105552-09954b6741cb
go: k8s.io/autoscaler/cluster-autoscaler@v0.0.0-20240320105552-09954b6741cb requires go >= 1.22; switching to go1.22.1
go: downloading go1.22.1 (darwin/arm64)
go: downloading k8s.io/autoscaler/cluster-autoscaler v0.0.0-20240320105552-09954b6741cb

Or, putting https://github.com/kubernetes/autoscaler/tree/09954b6741cbb910971916c079f45f6e8878d192/cluster-autoscaler/config/crd to https://github.com/kubernetes/autoscaler/tree/master/cluster-autoscaler/apis/provisioningrequest would be better.

@alculquicondor @x13n WDYT?

[x13n]

Putting the CRD in CA apis module makes sense to me, it has to be in sync with the code there anyway.

[alculquicondor]

I'm also ok upgrading to golang 1.22

But all the APIs should be in the separate module

[tenzen-y]

@x13n @alculquicondor Thank you for responding.
I can take both approaches.
Let me try them.

Thank you so much @tenzen-y!!!!

This was a long effort that simplifies the maintainability of our deps greatly!

@alculquicondor How about cherry-picking this into the release-0.6 branch?

[alculquicondor]

I'm not too sure about that. Why do you suggest it?

Also, I'm not sure what's the origin of the Job failure.

[tenzen-y]

I'm not too sure about that. Why do you suggest it?

Cherry-picking would allow cluster-admins to avoid #1345 error when cluster-admins implement a separate controller for the in-house job.

Also, I'm not sure what's the origin of the Job failure.

I'll try to investigate CI failure.

...
[FAILED] Test Report unavailable because a Ginkgo parallel process disappeared
    The aggregated report could not be fetched for a ReportAfterSuite node.  A
    Ginkgo parallel process disappeared before it could finish reporting.
...
This occurs if a parallel process exits before it reports its results to the
Ginkgo CLI.  The CLI will now print out all the stdout/stderr output it's
collected from the running processes.  However you may not see anything useful
in these logs because the individual test processes usually intercept output to
stdout/stderr in order to capture it in the spec reports.

Maybe this is the reason 🧐

[tenzen-y]

I guess that this error occurred by throttling CPU performance because integration tests often use larger CPUs.

It seems that we need to set 8 Cores in the limit.
@alculquicondor WDYT?

[alculquicondor]

One of my teammates is working in splitting the Multikueue E2E test into its own job. Let's decide if the limits are ok after that.
