'How to rolling restart pods without changing deployment yaml in kubernetes?

In kubernetes there is a rolling update (automatically without downtime) but there is not a rolling restart, at least i could not find. We have to change deployment yaml. Is there a way to make rolling "restart", preferably without changing deployment yaml?

Solution 1:[1]

Before kubernetes 1.15 the answer is no. But there is a workaround of patching deployment spec with a dummy annotation:

kubectl patch deployment web -p \
  "{\"spec\":{\"template\":{\"metadata\":{\"annotations\":{\"date\":\"`date +'%s'`\"}}}}}"

As of kubernetes 1.15 you can use:

kubectl rollout restart deployment your_deployment_name

CLI Improvements

  • Created a new kubectl rollout restart command that does a rolling restart of a deployment.
  • kubectl rollout restart now works for DaemonSets and StatefulSets

If you use k9s, the restart command can be found if you select deployments, statefulsets or daemonsets:
