This page describes how to resize the Google Distributed Cloud
control-plane node for the user cluster. Resizing the
control-plane node means adding or removing CPUs and changing the amount of
memory available to 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:
Console
In the console, go to the Google Kubernetes Engine clusters overview
page.
