ILIAS Helm Chart

This Helm chart deploys the ILIAS e-learning platform on a Kubernetes cluster. It supports deploying ILIAS with either a single MariaDB instance or a Galera cluster for high availability. It also includes deployment of the ILIAS RPC server, automatic database backups, and ILIAS cron jobs.

Prerequisites

• Kubernetes cluster
• Helm 3

Installing the Chart

1. Add the repository (if you haven't already):

helm repo add ilias-helm https://relaxdays.github.io/ilias-helm/
helm repo update

2. Install the chart:

helm install ilias ilias-helm/ilias -n <your-namespace> # Replace with your release name and namespace

Uninstalling the Chart

helm uninstall ilias -n <your-namespace> # Replace with your release name and namespace
