Upgrade Kasm on Kubernetes

This guide helps you determine your current Helm chart and choose the correct upgrade path for a Kasm Workspaces deployment on Kubernetes.

Prerequisites

• Administrator access to the Kubernetes cluster.
• kubectl and helm installed and configured.
• Backup and restore permissions.

Choose an upgrade path

Scenario	Use this guide
Upgrade the legacy kasm-single-zone chart 1.17.0 to 1.1181.0	Upgrade a legacy Helm deployment
Upgrade the kasm chart 1.1181.0 to 1.1190.0-develop	Upgrade an existing Helm deployment
Installed from the develop branch, between 1.18.1 and 1.19.0	Upgrade an existing Helm deployment

Determine your current chart version

To determine which Kasm Helm chart you use, run the following command:

helm list -n {NAMESPACE}

Interpret the output as follows.

For the legacy chart (kasm-single-zone), the output contains:

NAME    NAMESPACE       REVISION        UPDATED                                 STATUS          CHART                           APP VERSION
kasm    kasm            1               xxx                                     deployed        kasm-single-zone-1.17.0-develop 1.17.0

For the new chart (kasm), the output contains:

NAME    NAMESPACE       REVISION        UPDATED                                 STATUS          CHART           APP VERSION
kasm    kasm            1               xxx                                     deployed        kasm-1.1181.0   1.18.1
