Hi @namgon-kim. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@mdbooth how did we deal with PRs only for stable releases?

The least minimum is to retitle it to mention that.
I'm not against the idea but this has a cost, for maintenance and future cherry-pick conflicts when doing backports on other things.

/ok-to-test

[EmilienM]

The issue is fixed in main and is unreleased now:

https://github.com/kubernetes-sigs/cluster-api-provider-openstack/blob/1e39a380a979c6b3ac9a182e25749eab83740ac5/controllers/openstackcluster_controller.go#L566C25-L566C66

cluster-api-provider-openstack/controllers/openstackmachine_controller.go

Line 481 in 1e39a38

ServerMetadata: openStackMachineSpec.ServerMetadata,

So I'm fine fixing it only stable branches.

Looks like the linter broke in the stable branch :( How did that happen without making the tests fail?

I’ve noticed that the tests are failing due to linter errors across the project. Is there any specific action I need to take to resolve this?

I ran the linter locally and got the following results:
