This repository contains Docker configuration aimed at Moodle developers and testers to easily deploy a testing environment for Moodle.
- All supported database servers (PostgreSQL, MySQL, Micosoft SQL Server, Oracle XE)
- Behat/Selenium configuration for Firefox and Chrome
- Catch-all smtp server and web interface to messages using Mailpit
- All PHP Extensions enabled configured for external services (e.g. solr, ldap)
- All supported PHP versions
- Zero-configuration approach
- Backed by automated tests
- Docker and Docker Compose installed if your Docker CLI version does not support
docker composecommand. - It's recommended to always run the latest versions of each, but at the minimum Docker v20.10.15 and Docker Compose v2.5.0 should be used.
- 3.25GB of RAM (if you choose Microsoft SQL Server as db server)
# Change ./moodle to your /path/to/moodle if you already have it checked out
export MOODLE_DOCKER_WWWROOT=./moodle
# Choose a db server (Currently supported: pgsql, mariadb, mysql, mssql, oracle)
export MOODLE_DOCKER_DB=pgsql
# Get Moodle code, you could select another version branch (skip this if you already got the code)
git clone -b MOODLE_403_STABLE git://git.moodle.org/moodle.git $MOODLE_DOCKER_WWWROOT
# Ensure customized config.php for the Docker containers is in place

bin/moodle-docker-compose downBy default, the script will load a single instance. If you want to run two
or more different versions of Moodle at the same time, you have to add this
environment variable prior running any of the steps at Quick start:
# Define a project name; it will appear as a prefix on container names.
export COMPOSE_PROJECT_NAME=moodle34
# Use a different public web port from those already taken
export MOODLE_DOCKER_WEB_PORT=1234
# [..] run all "Quick steps" nowHaving set up several Moodle instances, you need to have set up
the environment variable COMPOSE_PROJECT_NAME to just refer
to the instance you expect to. See
envvars

localhost) from your browser. More info.
In order to run Behat tests for the Moodle App, you need to install the local_moodleappbehat plugin in your Moodle site. Everything else should be the same as running standard Behat tests for Moodle. Make sure to filter tests using the @app tag.
The Behat tests will be run against a container serving the mobile application, you have two options here:
-
Use a Docker image that includes the application code. You need to specify the
MOODLE_DOCKER_APP_VERSIONenv variable and the moodlehq/moodleapp image will be downloaded from Docker Hub. You can read about the available images in Moodle App Docker Images (for Behat, you'll want to run the ones with the-testsuffix). -
Use a local copy of the application code and serve it through Docker, similar to how the Moodle site is being served. Set the
MOODLE_DOCKER_APP_PATHenv variable to the codebase in you file system. This will assume that you've already initialized the app callingnpm installlocally.
For both options, you also need to set MOODLE_DOCKER_BROWSER to "chrome".
# Install local_moodleappbehat plugin
git clone https://github.com/moodlehq/moodle-local_moodleappbehat "$MOODLE_DOCKER_WWWROOT/local/moodleappbehat"
# Initialize behat environment
bin/moodle-docker-compose exec webserver php admin/tool/behat/cli/init.php
# (you should see "Configured app tests for version X.X.X" here)
# Run behat tests
bin/moodle-docker-compose exec -u www-data webserver php admin/tool/behat/cli/run.php --tags="@app&&@mod_login"

3m3.17s (55.02Mb)If you are going with the second option, this can be used for local development of the Moodle App, given that the moodleapp container serves the app on the local 8100 port. However, this is intended to run Behat tests that require interacting with a local Moodle environment. Normal development should be easier calling npm start in the host system.
By all means, if you don't want to have npm installed locally you can go full Docker executing the following commands before starting the containers:
docker run --volume $MOODLE_DOCKER_APP_PATH:/app --workdir /app bash -c "npm install"
You can learn more about writing tests for the app in Acceptance testing for the Moodle App.
If MOODLE_DOCKER_SELENIUM_VNC_PORT is defined, selenium will expose a VNC session on the port specified so behat tests can be viewed in progress.
For example, if you set MOODLE_DOCKER_SELENIUM_VNC_PORT to 5900..
- Download a VNC client: https://www.realvnc.com/en/connect/download/viewer/
- With the containers running, enter 0.0.0.0:5900 as the port in VNC Viewer. You will be prompted for a password. The password is 'secret'.
- You should be able to see an empty Desktop. When you run any Javascript requiring Behat tests (e.g. those tagged
@javascript) a browser will popup and you will see the tests execute.
bin/moodle-docker-compose down which was used above after using the containers stops and destroys the containers. If you want to use your containers continuously for manual testing or development without starting them up from scratch everytime you use them, you can also just stop without destroying them. With this approach, you can restart your containers sometime later, they will keep their data and won't be destroyed completely until you run bin/moodle-docker-compose down.
# Stop containers
bin/moodle-docker-compose stop
# Restart containers
bin/moodle-docker-compose startYou can change the configuration of the docker images by setting various environment variables before calling bin/moodle-docker-compose up.
When you change them, use bin/moodle-docker-compose down && bin/moodle-docker-compose up -d to recreate your environment.
| Environment Variable | Mandatory | Allowed values | Default value | Notes |
|---|---|---|---|---|
MOODLE_DOCKER_DB |
yes | pgsql, mariadb, mysql, mssql, oracle | none | The database server to run against |
MOODLE_DOCKER_WWWROOT |
yes | path on your file system | none | The path to the Moodle codebase you intend to test |
MOODLE_DOCKER_DB_VERSION |
no | Docker tag - see relevant database page on docker-hub | mysql: 8.0 pgsql: 13 mariadb: 10.7 mssql: 2017-latest oracle: 21 |
The database server docker image tag |
MOODLE_DOCKER_PHP_VERSION |
no | 8.1, 8.0, 7.4, 7.3, 7.2, 7.1, 7.0, 5.6 | 8.1 | The php version to use |
MOODLE_DOCKER_BROWSER |
no | firefox, chrome, firefox:<tag>, chrome:<tag> | firefox:3 | The browser to run Behat against. Supports a colon notation to specify a specific Selenium docker image version to use. e.g. firefox:2.53.1 can be used to run with older versions of Moodle (<3.5) |
MOODLE_DOCKER_PHPUNIT_EXTERNAL_SERVICES |
no | any value | not set | If set, dependencies for memcached, redis, solr, and openldap are added |
MOODLE_DOCKER_BBB_MOCK |
no | any value | not set | If set the BigBlueButton mock image is started and configured |
MOODLE_DOCKER_MATRIX_MOCK |
no | any value | not set | If set the Matrix mock image is started and configured |
MOODLE_DOCKER_BEHAT_FAILDUMP |
no | Path on your file system | not set | Behat faildumps are already available at http://localhost:8000/_/faildumps/ by default, this allows for mapping a specific filesystem folder to retrieve the faildumps in bulk / automated ways |
MOODLE_DOCKER_DB_PORT |
no | any integer value | none | If you want to bind to any host IP different from the default 127.0.0.1, you can specify it with the bind_ip:port format (0.0.0.0 means bind to all). Username is "moodle" (or "sa" for mssql) and password is "m@0dl3ing". |
MOODLE_DOCKER_WEB_HOST |
no | any valid hostname | localhost | The hostname for web |
MOODLE_DOCKER_WEB_PORT |
no | any integer value (or bind_ip:integer) | 127.0.0.1:8000 | The port number for web. If set to 0, no port is used. If you want to bind to any host IP different from the default 127.0.0.1, you can specify it with the bind_ip:port format (0.0.0.0 means bind to all) |
MOODLE_DOCKER_SELENIUM_VNC_PORT |
no | any integer value (or bind_ip:integer) | not set | If set, the selenium node will expose a vnc session on the port specified. Similar to MOODLE_DOCKER_WEB_PORT, you can optionally define the host IP to bind to. If you just set the port, VNC binds to 127.0.0.1 |
MOODLE_DOCKER_APP_PATH |
no | path on your file system | not set | If set and the chrome browser is selected, it will start an instance of the Moodle app from your local codebase |
MOODLE_DOCKER_APP_VERSION |
no | a valid app docker image version | not set | If set will start an instance of the Moodle app if the chrome browser is selected |
MOODLE_DOCKER_TIMEOUT_FACTOR |
no | any integer value | 1 | If set the timeouts in behat will be multiplied by the factor |
In addition to that, MOODLE_DOCKER_RUNNING=1 env variable is defined and available
in the webserver container to flag being run by moodle-docker. Developer
can use this to conditionally make changes in config.php. The common case is
to load test-specific configuration:
// Load moodle-docker config file if we are in moodle-docker environment
if (getenv('MOODLE_DOCKER_RUNNING')) {
require_once(__DIR__ . '/config.docker-template.php');
}
require_once(__DIR__ . '/lib/setup.php'); // Do not edit.
In some situations you may wish to add local customisations, such as including additional containers, or changing existing containers.
This can be accomplished by specifying a local.yml, which will be added in and loaded with the existing yml configuration files automatically. For example:
version: "2"
services:
# Add the adminer image at the latest tag on port 8080:8080
adminer:
image: adminer:latest
restart: always
ports:
- 8080:8080
depends_on:
- "db"
# Modify the webserver image to add another volume:
webserver:
volumes:
- "/opt/data:/opt/data:cached"
The XDebug PHP Extension is not included in this setup and there are reasons not to include it by default.
However, if you want to work with XDebug, especially for live debugging, you can add XDebug to a running webserver container easily:
# Install XDebug extension with PECL
moodle-docker-compose exec webserver pecl install xdebug
# Set some wise setting for live debugging - change this as needed
read -r -d '' conf <<'EOF'
; Settings for Xdebug Docker configuration
xdebug.mode = debug
xdebug.client_host = host.docker.internal
; Some IDEs (eg PHPSTORM, VSCODE) may require configuring an IDE key, uncomment if needed
; xdebug.idekey=MY_FAV_IDE_KEY
EOF
moodle-docker-compose exec webserver bash -c "echo '$conf' >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini"
# Enable XDebug extension in Apache and restart the webserver container
moodle-docker-compose exec webserver docker-php-ext-enable xdebug
moodle-docker-compose restart webserver
While setting these XDebug settings depending on your local need, please take special care of the value of xdebug.client_host which is needed to connect from the container to the host. The given value host.docker.internal is a special DNS name for this purpose within Docker for Windows and Docker for Mac. If you are running on another Docker environment, you might want to try the value localhost instead or even set the hostname/IP of the host directly. Please turn off the firewall or open the port used in the xdebug.client_port.
Open the port (9003 is the default one) by using the example command for Linux Ubuntu:
sudo ufw allow 9003
After these commands, XDebug ist enabled and ready to be used in the webserver container. If you want to disable and re-enable XDebug during the lifetime of the webserver container, you can achieve this with these additional commands:
# Disable XDebug extension in Apache and restart the webserver container
moodle-docker-compose exec webserver sed -i 's/^zend_extension=/; zend_extension=/' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
moodle-docker-compose restart webserver
# Enable XDebug extension in Apache and restart the webserver container
moodle-docker-compose exec webserver sed -i 's/^; zend_extension=/zend_extension=/' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
moodle-docker-compose restart webserver
As can be seen in bin/moodle-docker-compose, this repo is just a series of Docker Compose configurations and light wrapper which make use of companion docker images. Each part is designed to be reusable and you are encouraged to use the docker [compose] commands as needed.
Gitpod is a free, cloud-based, development environment providing VS Code and a suitable development environment right in your browser.
When launching a workspace in Gitpod, it will automatically:
- Clone the Moodle repo into the
<workspace>/moodlefolder. - Initialise the Moodle database.
- Start the Moodle webserver.
IMPORTANT: Gitpod is an alternative to local development and completely optional. We recommend setting up a local development environment if you plan to contribute regularly.
The Moodle Gitpod template supports the following environment variables:
MOODLE_REPOSITORY. The Moodle repository to be cloned. The value should be URL encoded. If left undefined, the default repositoryhttps://github.com/moodle/moodle.gitis used.MOODLE_BRANCH. The Moodle branch to be cloned. If left undefined, the default branchmainis employed.DATAFILE. When specified, this feature URL initializes the Moodle site with essential data. The value should be URL encoded. The content of this file adheres to the Behat generators format for creating testing scenarios.INSTALLADMINER. Add this variable, set to any value, to install adminer.CLONEALL. If not set, a shallow clone is created, truncating the history to reduce the clone size. Set to1for a full clone.
For a practical demonstration, launch a Gitpod workspace with the 'main' branch patch for MDL-79912. Simply open the following URL in your web browser (note that MOODLE_REPOSITORY should be URL encoded). The password for the admin user is test:
https://gitpod.io/#MOODLE_REPOSITORY=https%3A%2F%2Fgithub.com%2Fsarjona%2Fmoodle.git,MOODLE_BRANCH=MDL-79912-main/https://github.com/moodlehq/moodle-docker
To optimize your browsing experience, consider integrating the Tampermonkey extension into your preferred web browser for added benefits. Afterward, install the Gitpod script, which can be accessed via the following URL: Gitpod script. This script efficiently incorporates a button adjacent to each branch within the Moodle tracker, facilitating the effortless initiation of a Gitpod workspace tailored to the corresponding patch for the issue you're currently viewing.
The following Moodle customised docker images are close companions of this project:
- moodle-php-apache: Apache/PHP Environment preconfigured for all Moodle environments
- moodle-db-mssql: Microsoft SQL Server for Linux configured for Moodle
- moodle-db-oracle: Oracle XE configured for Moodle
