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?
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
- Created a new
kubectl rollout restartcommand that does a rolling restart of a deployment.kubectl rollout restartnow works for DaemonSets and StatefulSets
