Some of our containers run better with memory above the instance type currently deployed in our Container Engine cluster. Is there a recommended practice to rebuild the container engine template for larger instances after the container engine cluster has been created?
For example, go from GCE instances n1-standard-2 to n1-highmem-8 for running containers with above 8GB RAM?
There is an official GKE tutorial for this:
Migrating workloads to different machine types
"This tutorial demonstrates how to migrate workloads running on a GKE cluster to a new set of nodes within the same cluster without incurring downtime for your application. Such a migration can be useful if you want to migrate your workloads to nodes with a different machine type."
