Deploying ILIAS

Introduction

ILIAS is a powerful, open-source learning management system (LMS) used by educational institutions, businesses, and organizations worldwide. Originally developed at the University of Cologne, ILIAS has grown into one of the most comprehensive e-learning platforms available, supporting everything from traditional course management to sophisticated competency-based learning scenarios.

With its modular architecture and extensive feature set, ILIAS can handle the diverse needs of modern education - from universities running thousands of courses to corporate training departments delivering compliance training to global workforces.

Key highlights of ILIAS:

Course Management: Create and organize courses with lessons, materials, and assessments
Test and Assessment: Build quizzes and exams with various question types and automated grading
Content Authoring: SCORM support, learning modules, and built-in content creation tools
Collaboration Tools: Forums, wikis, blogs, and group workspaces
Competency Management: Track skills and competencies across learners
Portfolio System: Students can showcase their work and achievements
Certificate Management: Issue and verify completion certificates
User Management: LDAP, Shibboleth, CAS, and custom authentication
Multilingual: Available in numerous languages with full localization
Extensive API: RESTful API for integrations and custom applications
Plugin System: Extend functionality with community and custom plugins

This guide walks through deploying ILIAS on Klutch.sh using Docker, setting up a complete learning management platform.

Why Deploy ILIAS on Klutch.sh

Deploying ILIAS on Klutch.sh provides several advantages for e-learning delivery:

Simplified Deployment: Klutch.sh automatically detects your Dockerfile and builds ILIAS without complex server configuration. Push to GitHub and your LMS deploys automatically.

Persistent Storage: Attach persistent volumes for your database, uploaded files, and learning content. Your courses survive container restarts and redeployments.

HTTPS by Default: Klutch.sh provides automatic SSL certificates, ensuring secure access to your learning platform and protecting student data.

GitHub Integration: Connect your configuration repository directly from GitHub. Updates trigger automatic redeployments.

Scalable Resources: Allocate CPU and memory based on your learner population. Start small for pilot programs and scale up for institution-wide deployment.

Custom Domains: Assign a custom domain for a professional, branded learning experience.

Prerequisites

Before deploying ILIAS on Klutch.sh, ensure you have:

A Klutch.sh account
A GitHub account with a repository for your ILIAS configuration
Basic familiarity with Docker and containerization concepts
A MySQL or MariaDB database (can be deployed separately)
(Optional) LDAP server for enterprise authentication

Understanding ILIAS Architecture

ILIAS is built on a traditional LAMP stack with modern enhancements:

PHP Application: The core platform runs on PHP with an object-oriented architecture.

MySQL/MariaDB Database: Course structure, user data, and metadata are stored in the relational database.

File Storage: Learning materials, uploads, and generated content are stored on the filesystem.

Lucene Search: Optional full-text search powered by Java-based Lucene server.

Background Jobs: Cron-based tasks for notifications, maintenance, and cleanup.

Preparing Your Repository

To deploy ILIAS on Klutch.sh, create a GitHub repository containing your Dockerfile and configuration.

Repository Structure

ilias-deploy/
├── Dockerfile
├── php.ini
└── .dockerignore

Creating the Dockerfile

Create a Dockerfile in the root of your repository:

FROM srsolutions/ilias:8

# Set environment variables
ENV ILIAS_AUTO_SETUP=${ILIAS_AUTO_SETUP:-true}
ENV ILIAS_DB_HOST=${ILIAS_DB_HOST}
ENV ILIAS_DB_USER=${ILIAS_DB_USER:-ilias}
ENV ILIAS_DB_PASSWORD=${ILIAS_DB_PASSWORD}
ENV ILIAS_DB_NAME=${ILIAS_DB_NAME:-ilias}

# PHP Configuration
ENV ILIAS_MEMORY_LIMIT=${ILIAS_MEMORY_LIMIT:-512M}
ENV ILIAS_MAX_UPLOAD_SIZE=${ILIAS_MAX_UPLOAD_SIZE:-500M}

# Timezone and locale
ENV ILIAS_TIMEZONE=${ILIAS_TIMEZONE:-UTC}
ENV TZ=${TZ:-UTC}

# Initial admin password
ENV ILIAS_ROOT_PASSWORD=${ILIAS_ROOT_PASSWORD}

# Create necessary directories
RUN mkdir -p /var/iliasdata/ilias /var/log/ilias

# Set permissions
RUN chown -R www-data:www-data /var/iliasdata /var/log/ilias

# Expose port 80
EXPOSE 80

# Health check
HEALTHCHECK --interval=60s --timeout=30s --start-period=120s --retries=3 \
  CMD wget --no-verbose --tries=1 --spider http://localhost:80/ || exit 1

# Volumes for persistent data
VOLUME ["/var/iliasdata", "/var/www/html/data"]

PHP Configuration (php.ini)

Create a php.ini file for custom PHP settings:

memory_limit = 512M
upload_max_filesize = 500M
post_max_size = 500M
max_execution_time = 300
max_input_vars = 10000
date.timezone = UTC

Deploying ILIAS on Klutch.sh

Once your repository is prepared, follow these steps to deploy ILIAS:

Set Up Your Database

ILIAS requires a MySQL or MariaDB database. You can:

Deploy a database app on Klutch.sh
Use a managed database service
Use an existing database server

Ensure the database user has full privileges on the ILIAS database.

Push Your Repository to GitHub

Initialize your repository and push to GitHub:

git init
git add Dockerfile php.ini .dockerignore
git commit -m "Initial ILIAS deployment configuration"
git remote add origin https://github.com/yourusername/ilias-deploy.git
git push -u origin main

Create a New Project on Klutch.sh

Navigate to the Klutch.sh dashboard and create a new project. Give it a descriptive name like “learning” or “ilias”.

Create a New App

Within your project, create a new app. Connect your GitHub account if you haven’t already, then select the repository containing your ILIAS Dockerfile.

Configure HTTP Traffic

ILIAS serves its web interface over HTTP. In the deployment settings:

Select HTTP as the traffic type
Set the internal port to 80

Set Environment Variables

In the environment variables section, add the following:

Variable	Value
`ILIAS_DB_HOST`	Your database hostname
`ILIAS_DB_USER`	Database username
`ILIAS_DB_PASSWORD`	Database password
