gcloud container clusters resize - resizes an existing cluster for running containers
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 ...]
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.
To resize the default node pool of an existing cluster, run:
$ gcloud container clusters resize sample-cluster --num-nodes=2
- 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:
- --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.
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.
