Kubernetes：如何优雅地删除 daemonset 中的 Pod？

Question

If there is an update in the docker image, rolling update strategy will update all the pods one by one in a daemonset, similarly is it possible to restart the pods gracefully without any changes the daemonset config or can it be triggered explicitly?

Currently, I am doing it manually by

kubectl delete pod <pod-name> One by one until each pod gets into running state.

Answer 1

You could try and use Node maintenance operations :

Use kubectl drain to gracefully terminate all pods on the node while marking the node as unschedulable (with --ignore-daemonsets , from Konstantin Vustin 's comment ):

kubectl drain $NODENAME --ignore-daemonsets

This keeps new pods from landing on the node while you are trying to get them off.

Then:

Make the node schedulable again:

kubectl uncordon $NODENAME

要触发名称空间 [namespace_name] 中由 deamonset 管理的所有 pod 的重启：

 kubectl rollout restart de -n [namespace_name]
