Docker Swarm Configuration

We are using a Docker Swarm configuration with Traefik as a reverse proxy. Here's an example of a docker-compose.yml file:

Environment Variable

WordPress

For WORDPRESS_NO_CREATE_CONFIG: Do not create a new configuration file (default: false)

By default, the image will use a new configuration file which is generated at runtime and after you can use WordPress environnement.

If you want to use your own configuration file, set this variable to true.

For WORDPRESS_CONFIG_EXTRA, you can use the following variables:

apacheconf
WORDPRESS_CONFIG_EXTRA: |
    define( 'DISALLOW_FILE_MODS', true );
    define( 'WP_MEMORY_LIMIT', '511M' );
    define( 'WP_REDIS_HOST', 'mysite.redis');
