3.2. Google Cloud Platform

You can change the number of nodes of a Red Hat OpenShift Container Platform cluster that was created in an Google Cloud Platform environment by modifying the MachineSet parameters on the hub cluster.

Remember: Because Red Hat Advanced Cluster Mangement for Kubernetes uses Hive for OpenShift to determine the number of nodes in the cluster, you must change the MachineSet parameter to change the number of nodes. If you just remove or add a node without changing the MachineSets parameter, nodes are added or removed to match the current value of that parameter.

See Recommended cluster scaling practices and Manually scaling a MachineSet in the OpenShift Container Platform documentation that applies to your version for more information about scaling your cluster. Tip: If you created the cluster by using Red Hat Advanced Cluster Management, then it is an OpenShift Container Platform cluster.

If you are changing the number of nodes of a Google Kubernetes Engine cluster that you imported, see Resizing a cluster for information about scaling the cluster.
