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
