gcloud container clusters resize - resizes an existing cluster for running containers

gcloud container clusters resizeNAME(--num-nodes=NUM_NODES    |--size=NUM_NODES)[--async][--node-pool=NODE_POOL][--location=LOCATION    |--region=REGION    |--zone=ZONE,-zZONE][GCLOUD_WIDE_FLAG …]

If you have multiple node pools, you must specify which node pool to resize byusing the --node-pool flag. You are not required to use the flag if you have asingle node pool.

When increasing the size of a container cluster, the new instances are createdwith the same configuration as the existing instances. Existing pods are notmoved onto the new instances, but new pods (such as those created by resizing areplication controller) will be scheduled onto the new instances.

When decreasing a cluster, the nodes are drained. As a result, the pods runningon these nodes are gracefully terminated. If your pods are being managed by aworkload controller, the controller will attempt to reschedule them onto theremaining instances. If your pods are not managed by a workload controller, theywill not be restarted. Note that when resizing down, instances running pods andinstances without pods are not differentiated. Resize will pick instances toremove at random.

When you resize a node pool that spans multiple zones, the new size representsthe number of nodes in the node pool per zone. For example, if you have a nodepool of size 2 spanning two zones, the total node count is 4. If you resize thenode pool with--num-nodes=4, the total node count becomes 8.

NAME

The name of this cluster.

Exactly one of these must be specified:

--num-nodes=NUM_NODES

Target number of nodes in the cluster.

--size=NUM_NODES

(DEPRECATED) Target number of nodes in the cluster.

The --size flag is now deprecated. Please use--num-nodes instead.

--async

Return immediately, without waiting for the operation in progress to complete.

--node-pool=NODE_POOL

The node pool to resize.

At most one of these can be specified:

--location=LOCATION

Compute zone or region (e.g. us-central1-a or us-central1) for the cluster.Overrides the default compute/region or compute/zone value for this commandinvocation. Prefer using this flag over the --region or --zone flags.

--region=REGION

Compute region (e.g. us-central1) for a regional cluster. Overrides the defaultcompute/region property value for this command invocation.

--zone=ZONE,-zZONE

Compute zone (e.g. us-central1-a) for a zonal cluster. Overrides the defaultcompute/zone property value for this command invocation.
