Hi @Iceber. Thanks for your PR.

I'm waiting for a containerd 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.

@Iceber, your change is not related to the failed case. I still am working on the case. Sorry for that inconvenient.

restarting ci after we merged in the fix. If this still fails, can you rebase your branch?

This will need a rebase on master to get the perms fix for /etc/ CNI dir
