How to forcefully delete a daemonset or a pod in kubernetes cluster

Question

I have setup a kubernetes cluster which is working fine. I created deployment with type as daemonset which then created few pods and it worked fine. I made few changes so I deleted the daemonset using:

kubectl delete daemonset <name> --namespace=clustech

While few pods were getting deleted, few of the machine went offline and thus the pods running on them went on to say unknown status. I need to remove those pods or completely remove that previous daemonset but unable to do. I am using below commands to delete pods:

kubectl delete pod PODNAME --grace-period=0 --force

But this shows below error:

warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
Error from server (NotFound): pods "deployment-6sj54" not found

How can I delete the pods.?

Answer 1

Re-run the second command with namespace parameter will do your job.

--grace-period=0 --force is the right command to delete such pods.

Answer 2

You can delete a daemonset.apps using this command:

kubectl delete --all daemonset.apps -n <namespace>
