Docker Pulls Docker image layers nginx 1.18.0 php 7.3 moodle-3.9 License MIT

Moodle on Alpine Linux

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
