Upgrade Cluster Autoscaler

This guide will walk you through upgrading the Cluster Autoscaler, to ensure that you use the latest version supported by your EKF cluster.

Attention

This guide assumes that you have already deployed the Cluster Autoscaler on your cluster.

If this does not hold, and you want to deploy the Cluster Autoscaler now, proceed to the corresponding guide for deploying the Cluster Autoscaler on your cluster. Then, return to this guide and proceed to the What’s Next section.

Fast Forward

If you have not deployed the Cluster Autoscaler and you do not wish to deploy it, expand this box to fast-forward.

1. Proceed to the What’s Next section.

What You’ll Need

• An upgraded management environment.
• Your clone of the Arrikto GitOps repository.
• Arrikto manifests for EKF version 2.1-pre-493-g657799a9c.
• A working Cluster Autoscaler.

Procedure

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

Verify

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

Summary

You have successfully upgraded the Cluster Autoscaler.

What’s Next

The next step is to test your upgraded deployment.
