Kubernetes Upgrade

This document outlines the process for upgrading Kubernetes and its internal components. 

Note: This upgrade is independent of Labforward's product release cycle and should not have any functional impact.

Release Schedule

Labforward adheres to Kubernetes' official release schedule (Releases) with a three-month lag. 

Here are the upcoming Labforward Platform upgrades:

• April 2024: Kubernetes 1.30
• July 2024: Kubernetes 1.31

Supported Versions

Labforward provides support for the three most recent Kubernetes versions following the Release Schedule. 

Please note that the functionality of the applications in any other version is not assured.

Here is the list of currently supported Kubernetes versions:

• Kubernetes 1.29
• Kubernetes 1.28
• Kubernetes 1.27
• Kubernetes 1.26

Upgrade Process

In the Kubernetes host, run:

curl -sSL https://kurl.sh/labforward-customer-channel  | sudo bash

Tip: You can review the list of all add-ons that will be upgraded or installed at the following URL: https://kurl.sh/labforward-customer-channel

Tip: If you are managing your own Kubernetes cluster, deployed independently of the Labforward installer, it is the responsibility of the IT administrator to handle cluster updates using their preferred method.
