Hi @cola-zero. 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/test-infra repository.

I have tested a "switch" from docker to containerd upgrade on a VM cluster on the latest stable (2765.2.6) Flatcar Linux using this PR.

Everything seemed to go smoothly, but it seems like this deploys the apiserver, scheduler and kube-controller-manager through systemd units using containerd-shim.

After the "switch" finished successfully, everything was running, but inside the cluster, it still was continuing to attempt to schedule those kube process pods and failing as the ports are already bound to by the systemd units.

Is this intended behavior? Do I need to somehow clean them up manually?

I can provide more info if required.

@floryut @oomichi Thank you for review!

@Vilsol Thank you for test this PR. I also test switch docker to containerd and I need reboot nodes to get cluster healthy.
If you want healthy cluster without reboot, I think it would be nice to create new issue.

Vilsol commented Jul 21, 2021

@cola-zero Indeed it looks like after node reboot cluster becomes healthy with everything running, some workloads enter a failed state, but they can be simply rescheduled.
