+<1> Scale the worker machines based on the number of worker nodes that are part of the {product-title} cluster. Valid options for the `replicas` value are `0` and integers greater than or equal to `2`. Set the number of replicas to `0` to deploy a three-node cluster, which contains only three control plane machines. A three-node cluster is a smaller, more resource-efficient cluster that can be used for testing, development, and production. You cannot install the cluster with only one worker.
