Upgrade Cluster Autoscaler

This guide will walk you through upgrading the Cluster Autoscaler.


This guide assumes that you have already deployed the Cluster Autoscaler on your cluster. If this does not hold, please proceed to the corresponding guide for deploying the Cluster Autoscaler on your cluster. Ensure that your kustomization uses the corresponding overlay for your Kubernetes version.

What You’ll Need


  1. Go to your GitOps repository, inside your rok-tools management environment:

    root@rok-tools:~# cd ~/ops/deployments
  2. Apply the kustomization:

    root@rok-tools:~/ops/deployments# rok-deploy --apply rok/cluster-autoscaler/overlays/deploy


  1. Verify that the Cluster Autoscaler is up-and-running. Verify that field READY is 1/1:

    root@rok-tools:~# kubectl get -n kube-system deploy/cluster-autoscaler NAME READY UP-TO-DATE AVAILABLE AGE cluster-autoscaler 1/1 1 1 1m


You have successfully upgraded the Cluster Autoscaler on your cluster.
