NAME¶
kubectl rolling-update - Perform a rolling update. This command is deprecated, use rollout instead.
SYNOPSIS¶
kubectl rolling-update [OPTIONS]
DESCRIPTION¶
Perform a rolling update of the given ReplicationController.
Replaces the specified replication controller with a new replication controller by updating one pod at a time to use the new PodTemplate. The new-controller.json must specify the same namespace as the existing replication controller and overwrite at least one (common) label in its replicaSelector.
