CON-34562 - add ocean-right-sizing-controller Helm chart

[alextarasov-spot]

https://spotinst.atlassian.net/browse/CON-34562

Why

To deliver a standalone solution for Ocean Right-Sizing, we must provision a dedicated Ocean controller with the Ocean autoscaler explicitly disabled. Additionally, the controller should be granted minimal RBAC permissions, scoped strictly to the operations required for right-sizing functionality.

What

• create a new ocean-right-sizing-controller Helm chart
• granted minimal RBAC permissions
• the controller should be “read-only”
• a cluster with the ocean-right-sizing-controller should not perform autoscaling

How to test

Install Helm chart

helm install ocean-right-sizing-controller ocean-right-sizing-controller --dry-run --namespace spot-system \
--namespace "spot-system" \
--set spotinst.account="act-12f6b1b9" \
--set spotinst.clusterIdentifier=alex-rightsizing-demo \
--set spotinst.token="<TOKEN>" \
--set metrics-server.deployChart=true

• the ocean-right-sizing-controller installed in the expected NS
• the controller reports to cluster and heartbeat is active
• the ocean-vpa is installed
  • ocean-vpa-updater is running
  • ocean-vpa-admission-wwebhook is running

Test Right-Sizing
