Moodle setup for Docker, build on Alpine Linux. The image is only +/- 70MB large.

Repository: https://github.com/erseco/alpine-moodle

• Built on the lightweight image https://github.com/erseco/alpine-php7-webserver
• Very small Docker image size (+/-70MB)
• Uses PHP 7.3 for better performance, lower cpu usage & memory footprint
• Multi-arch support: 386, amd64, arm/v6, arm/v7, arm64, ppc64le, s390x
• Optimized for 100 concurrent users
• Optimized to only use resources when there's traffic (by using PHP-FPM's ondemand PM)
• Use of runit instead of supervisord to reduce memory footprint
• Configured cron to run as non-privileged user gliderlabs/docker-alpine#381 (comment)
• docker-compose sample with PostgreSQL
• Configuration via ENV variables
• Easily upgradable to new moodle versions
• The servers Nginx, PHP-FPM run under a non-privileged user (nobody) to make it more secure
• The logs of all the services are redirected to the output of the Docker container (visible with docker logs -f <container name>)
• Follows the KISS principle (Keep It Simple, Stupid) to make it easy to understand and adjust the image to your needs

Start the Docker containers:

docker-compose up

Login on the system using the provided credentials (ENV vars)

Define the ENV variables in docker-compose.yml file
