All services that make up the development environment take a common form.
For example, the memcached service has the following commands:
Available Commands: create Create the memcached containers destroy Destroy the memcached containers exec Execute a command in the main memcached container resume Resume the memcached containers suspend Suspend the memcached containers
Some services may have extra convenience commands, for example:
Many services have environment variables that can be set to modify behaviour, or even change the image being used.
You can always take a look at the docker-compose files used, and thus environment variables that can be set.
cat $(mw dev where)/memcached.yml
Altering a variable
If you want to alter an environment variable on a container, you'll need to re create the container after the change.
mw docker env set MEDIAWIKI_XDEBUG_CONFIG "client_host=172.21.112.105" mw docker mediawiki create
You should see that the container recreates:
Recreating mwcli-mwdd-default_mediawiki_1 ... done
Using a different docker image
You may want to use a different base image for your MediaWiki container.
For example, you might want to use a different PHP version than the default.
You can do so by setting the
MEDIAWIKI_IMAGE environment variable:
mw docker env set MEDIAWIKI_IMAGE docker-registry.wikimedia.org/dev/buster-php74-fpm:1.0.0 mw docker mediawiki create
