To enable autoscaling for an existing node pool, run the following command:

gcloud container clusters update [CLUSTER_NAME] --enable-autoscaling \ --min-nodes 1 --max-nodes 10 --zone [COMPUTE_ZONE] --node-pool default-pool

In this command:

  • --enable-autoscaling indicates that autoscaling is enabled.

  • --node-pool specifies the node pool for which autoscaling is enabled.

  • --min-nodes specifies the minimum number of nodes for the node pool.

  • --max-nodes specifies the maximum number of nodes for the node pool.

  • --zone specifies the cluster's [compute zone].

  • --node-pool specifies the desired node pool. If you have only one node pool, supply default-pool to this flag.
