Autoscale worker nodes on a cluster to increase or decrease the number of resources available. Autoscaling for worker nodes is configured in the machine pool definition if you are configuring an existing cluster.

Additionally, you can configure autoscaling on the default machine pool when you create the cluster using interactive mode.

Disabling autoscaling nodes in an existing cluster

Disable autoscaling for worker nodes in the machine pool definition.

  1. Enter the following command:

    $ rosa edit machinepool --cluster=<cluster_name> <machinepool_ID> --enable-autoscaling=false --replicas=<number>

    Disable autoscaling on the default machine pool on a cluster named mycluster:

    $ rosa edit machinepool --cluster=mycluster default --enable-autoscaling=false --replicas=3
