Docker container for Moodle

This is everything you need to run Moodle 3.2.0 in one simple container.

It wraps MariaDB, Nginx, PHP5 to make it easy to quickly get started.

Building the image

To build the image, simply run:

bash> docker build -t imagename .

(You can replace /imagename/ with whatever you want. I use "moodle")

First install

Preparing volumes

Three volumes are needed:

Moodle itself - /var/www/ ** Since Moodle plugins work by installing them selves into the Moodle directory, it must be preserved and writable for Moodle itself.
Moodle data - /var/moodledata/ ** This is where uploaded documents etc. are stored
MariaDB data files - /var/lib/mysql/

For simplicity, these volumes are stored externally to the image itself.

To create the volumes, you need three empty directorys, i.e.:

bash> mkdir /data/moodle/www
bash> mkdir /data/moodle/moodledata
bash> mkdir /data/moodle/db

(You may call these directories whatever you like, and you may put them wherever you like.)

Installing database and Moodle distribution

When you first start the container, the MariaDB database and the Moodle distribution files must be initialized.

To initialize the MariaDB database, run:

bash> docker run -ti --rm -v /data/moodle/www:/var/www -v /data/moodle/moodledata:/var/moodledata -v /data/moodle/db:/var/lib/mysql moodle install-db

To install the Moodle distribution files, run:

bash> docker run -ti --rm -v /data/moodle/www:/var/www -v /data/moodle/moodledata:/var/moodledata -v /data/moodle/db:/var/lib/mysql moodle install-moodle

Running the service

The container listens to HTTP requests on port 80, and you need to redirect a port (typically 80).

To actually start the service, run:

bash> docker run -d -v /data/moodle/www:/var/www -v /data/moodle/moodledata:/var/moodledata -v /data/moodle/db:/var/lib/mysql -p 80:80 moodle run

Configuring Moodle

To start configuring Moodle, enter the URL in your web browser (i.e. http://localhost:portnumber/).

The Moodle configuration "wizard" will now ask a number of questions about timezones, etc. When it asks for database information, you need to select 'mariadb/native', and enter the socket as '/var/lib/mysqld.sock'.

After this, everything should be up and running.

Backup / restore
