It needs sometime for kubelet to remove the pod. Could you wait a while and check whether the Pod removed?
Hi actually I have waited for 1 day, and it is not deleting. Can delete it only using --grace-period=0 --force. But I don't want to use this manual approach). Could you pls give some advice on this? Thanks in advance!
is a reference to this issue. Checking kubelet logs will always help to troubleshoot such problem.
Actually, I have attached kubelet log in the ticket and think the main reason is Also as there any option for kubelet to automatically force delete Terminating pods after some period? And --containerized is also not solving my issue. Thanks!
Kubelet won't delete the pod from apiserver. Since it is already not exist on the node, you could force delete it by kubectl.
It is clear, so how we can resolve this error: ? I think this is the core item of our issue. Thanks.
I'm not using OVN. Have you met this problem when using OVN?
adding Bob to comment on this. i have seen this issue before, but it has been quite a while.
Hi, Guys will be very grateful if you will provide some solution for it. We have tried to add to deployment spec but it doesn't help. Thanks.
The error message of is actually a warning message. It shouldn't block the removal of pods. Could you recheck the following things: the node, check whether the pod is still existing, e.g. by the pod exists, check if there are other error or warning message in kubelet logs; or else, the pod could be force removed safely from apiserver
Hi, I had posted this info in the ticket description. not showing this container, so it is completely deleted, but in kubectl it is displayed as Terminating.
i think you may get more support and faster responses in our slack channel for sig-windows.
So it could be safely force removed from API. And agreed with slack is a more faster way to such troubleshooting issues.
The issue seems to be related to . The only platform specific implementation for PodContainerManager is the one for . There is a default implementation (), that always returns true in the Exists call. Disabling the CgroupsPerQOS option on the Windows nodes resolves the issue.
Windows doesn't support cgroups. You should always disable it.
it is clear enough that Windows does not support cgroups). Unfortunately, it's not specified in the documentation. So to disable CgroupsPerQOS you should need to add this flags to kubelet: Maybe it will help someone... Thank you all for discussion!
