Moodle Docker image

This is a somewhat opinionated Docker image for running Moodle, currently used by VATSIM. It is based on the official PHP+Apache image and includes the following:

• Moodle and its required PHP extensions
• atto_morefontcolors plugin
• mod_customcert plugin
• tool_forcedcache plugin

Usage

MySQL/MariaDB and Redis are required to run this image. You'll also need to configure some way of running Moodle's cron job, such as a cron container or a Kubernetes CronJob.
