红帽全球峰会第 3 章 Resizing a cluster
You can customize your managed cluster specifications, such as virtual machine sizes and number of nodes. See the following list of recommended settings for each available provider, but also see the documentation for more specific information:
3.1. Amazon Web Services
You can change the number of nodes of a Red Hat OpenShift Container Platform cluster that was created in an Amazon Web Services 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.
Tip: If you created the cluster by using the Red Hat Advanced Cluster Management for Kubernetes console, then it is an OpenShift Container Platform cluster.
If you are changing the number of nodes of an Amazon EKS cluster that you imported, see Cluster autoscaler for information about scaling the cluster.
