Hi @mszadkow. 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

Please expand on:

  • which subcomponents of MK each external controller is implementing (even if provided by a framework)
  • how does a configuration for multiple of these controllers look like from the ClusterQueue point of view.

The integration test scenario seemed reasonable to me.

Providing a mechanism to register an external controller and have it coordinate with the builtin components about which GVKs each is responsible seems right.

There was not sufficient detail for me as a MultiKueue outsider to understand how the pieces fit together and what I'd need to do to add an external custom Job. Is this KEP also supposed to cover external Job adapters too?

Yes, it's supposed to enable the easy creation of them. I agree that the proposal needs more detail.
