Example usage

The following command will expose the current working directory on port 8080:

$ docker run --name web0 -p 8080:80  -v $PWD:/var/www/html moodlehq/moodle-php-apache:7.1

Features

• Preconfigured with all php extensions required for Moodle development and all database drivers
• Serves wwroot configured at /var/www/html/
• For PHP 7.3 and up, both linux/amd64 and linux/arm64 images are being built. Note that linux/arm64 doesn't support the sqlsrv and oci extensions yet. Other than that, both architectures work exactly the same.
• Verified by automated tests.
• Autobuilt from GHA, on push.
• Support for entrypoint scripts and PHP Configuration
• Many common extensions available

Directories

To facilitate testing and easy setup the following directories are created and owned by www-data by default:

• /var/www/moodledata
• /var/www/phpunitdata
• /var/www/behatdata
• /var/www/behatfaildumps

Initialisation scripts

If you would like to do additional initialization, you can add one or more *.sh, or *.ini scripts under /docker-entrypoint.d (creating the directory if necessary). When the entrypoint script is called, it will run any executable *.sh script, source any non-executable *.sh scripts found in that directory, and will copy any *.ini scripts into the PHP Configuration directory (/usr/local/etc/php/conf.d).

For example, to configure PHP to support a higher upload_max_filesize option you might add the following to a config/10-uploads.ini file:

; Specify a max filesize of 200M for uploads.
upload_max_filesize = 200M
post_max_size = 210M

When starting your container you could do so passing in the config directory:

docker run \
    --name web0 \
    -p 8080:80 \
    -v $PWD/moodle:/var/www/html
    -v $PWD/config:/docker-entrypoint.d \
    moodle-php-apache:latest

These initialization files will be executed in sorted name order as defined by the current locale, which defaults to en_US.utf8.

PHP Configuration

As a lightweight alternative to a full PHP configuration file, you can specify a set of prefixed environment variables when starting your container with these variables turned into ini-format configuration.

Any environment variable whose name is prefixed with PHP_INI- will have the prefix removed, and will be added to a new ini file before the main command starts.

docker run \
    --name web0 \
    -p 8080:80 \
    -v $PWD/moodle:/var/www/html
    -e PHP_INI-upload_max_filesize=200M \
    -e PHP_INI-post_max_size=210M \
    moodle-php-apache:latest
