Capacity changes for the shared Kubernetes clusters.

File contents

Scale Cluster

Adds or removes node capacity, and adjusts the autoscaler bounds that decide how far it can move on its own.

Before changing anything

Read the current headroom from the capacity dashboard. A cluster under 20% headroom at peak is scaled up before any other change.

Making the change

Node pools are declared in the cluster manifest. Change the manifest, not the live cluster; the reconciler reverts manual edits within ten minutes.
