Upgrade EKS Managed Node Groups

This section will guide you through upgrading the managed node groups of your EKS cluster to match the Kubernetes version of the control plane. The procedure is automated for EKS clusters with managed node groups using the rolling update strategy, and thus you can perform it with the click of a button.

Procedure

  1. Open your browser, and go to the Amazon EKS console at https://console.aws.amazon.com/eks/home#/clusters.

  4. On the Update Node Group version page, select rolling update as the update strategy. This policy respects the pod disruption budgets and ensures proper draining without data loss. Then click Update.

Verify

  1. Go to your rok-tools management environment.

  2. Ensure that all nodes in the node group are ready and run the new Kubernetes version. Check that field STATUS is Ready and field VERSION shows the new Kubernetes version:

    root@rok-tools:~# kubectl get nodes
NAME                                              STATUS   ROLES   AGE     VERSION
ip-172-31-32-188.eu-central-1.compute.internal    Ready    <none>   1h     v1.19.13-eks-8df270
ip-172-31-34-84.eu-central-1.compute.internal     Ready    <none>   1h     v1.19.13-eks-8df270

Summary

You have successfully upgraded your managed node group.
