This page describes how to resize the Anthos clusters on VMware (GKE on-prem) control-plane node for the user cluster. Resizing the control-plane node means adding or removing CPUs and changing the amount of memory from the control-plane node for the user cluster.
You cannot resize the control-plane node manually if you have enabled automatic node resizing.
To add or remove CPUs and memory in the control-plane node:
Edit the user cluster configuration file. Change the
masterNode.memoryMBvalues as desired.
... masterNode: cpus: 4 memoryMB: 8192 # How many machines of this type to deploy replicas: 3 ...
Run this command to update the cluster:
gkectl update cluster --kubeconfig ADMIN_CLUSTER_KUBECONFIG --config USER_CONFIG_FILE
Replace ADMIN_CLUSTER_KUBECONFIG with the path of your admin cluster kubeconfig file. Replace USER_CONFIG_FILE with the path of your user cluster configuration file.
