gcloud container clusters resize - resizes an existing cluster for running containers
gcloud container clusters resize NAME --size SIZE [--wait] [--zone ZONE, -z ZONE] [GLOBAL-FLAG ...]
gcloud container clusters resize resize an existing cluster to a provided size.
When increasing the size of a container cluster, the new instances are created with the same configuration as the existing instances. Existing pods are not moved onto the new instances, but new pods (such as those created by resizing a replication controller) will be scheduled onto the new instances.
When decreasing a cluster, the pods that are scheduled on the instances being removed will be killed. If your pods are being managed by a replication controller, the controller will attempt to reschedule them onto the remaining instances. If your pods are not managed by a replication controller, they will not be restarted. Note that when resizing down, instances running pods and instances without pods are not differentiated. Resize will pick instances to remove at random.
NAMEThe name of this cluster.
--size SIZETarget number of nodes in the cluster.
--waitPoll the operation for completion after issuing an resize request. Enabled by default, use --no-wait to disable.--zone ZONE, -z ZONE
The compute zone (e.g. us-central1-a) for the cluster
