Upgrading Kubernetes Bundles

Use this procedure to upgrade the Kubernetes to latest versions, without performing the complete HPE Ezmeral Runtime Enterprise upgrade. However, An upgrade of Kubernetes that requires changes to platform can be done only through HPE Ezmeral Runtime Enterprise upgrade.

Prerequisites

Required access rights: Platform Administrator

About this task

Starting from HPE Ezmeral Runtime Enterprise 5.5.0, Kubernetes bundles can be upgraded, without performing the platform upgrade.

Procedure

If you have non-airgapped environment, ignore this step and skip to the next step. If you have an air-gapped environment:
1. Download the latest Kubernetes add-on images and the latest Bootstrap images.
2. Copy all the downloaded files to the appropriate air-gap repository locations.
Download the Kubernetes bundle, for example, hpe-kubernetes-<version>.bin, and place it in /srv/bluedata/bundles directory on the controller node of HPE Ezmeral Runtime Enterprise.
On Settings Update, under the Available Kubernetes Bundle Updates section, select the Kubernetes bundle, and click the respective Update button.

The Confirm Kubernetes Bundle Update appears. Check the details and click Update button.

NOTE After successful update, you can click View Kubernetes Bundle Update History to see the update history.
If you want to perform the standard Kubernetes Upgrade on existing Kubernetes cluster, see Upgrading Kubernetes to a Later Version.
If you want to upgrade the Kubernetes add-ons, see Upgrading Kubernetes Add-Ons.
