Upgrading the EKS Control Plane

This version of the platform requires Kubernetes 1.20. Because Amazon EKS runs a highly-available control plane, you can upgrade only one minor version in one step. Therefore, if your current version is 1.18 and you wish to upgrade to 1.20, then you must first upgrade your cluster to 1.19 and then upgrade it from 1.19 to 1.20. If your current version is 1.19, you will be able to upgrade in one step.

Note: Each EKS control plane upgrade can take 20-30 minutes to complete.
  1. In AWS, browse to the EKS console.
  2. Click Clusters.

  3. In the list of clusters, next to your cluster, click Upgrade now.

  4. Select the next Kubernetes minor version, and then click Update.
  5. (Conditional) If you are originally upgrading from version 1.18, repeat steps 3-4 to complete the upgrade from version 1.19 to 1.20.

Before proceeding, wait until the Status changes from Updating to Active.
