NAME

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

SYNOPSIS

gcloud container clusters resize NAME (--num-nodes=NUM_NODES | --size=NUM_NODES) [--async] [--node-pool=NODE_POOL] [--region=REGION | --zone=ZONE, -z ZONE] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION

Resize an existing cluster to a provided size.

If you have multiple node pools, you must specify which node pool to resize by using the --node-pool flag. You are not required to use the flag if you have a single node pool.

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 nodes are drained. As a result, the pods running on these nodes are gracefully terminated. If your pods are being managed by a workload controller, the controller will attempt to reschedule them onto the remaining instances. If your pods are not managed by a workload 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.

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

EXAMPLES

To resize the default node pool of an existing cluster, run:

$ gcloud container clusters resize sample-cluster --num-nodes=2

POSITIONAL ARGUMENTS

NAME

The name of this cluster.

REQUIRED FLAGS

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.

OPTIONAL FLAGS

--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:
--region=REGION

Compute region (e.g. us-central1) for the cluster.

--zone=ZONE, -z ZONE

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

GCLOUD WIDE FLAGS

These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.

Run $ gcloud help for details.
