XDebug
To use XDebug with MediaWiki running inside a docker container, you have to tell the PHP environment running inside the container to connect to the IDE on the host machine. Tho do this, set the  variable in your   file:

The following values may have to be adjusted for your system: For details on how to set up different IDEs to allow debugging inside the docker container, see:
 *  : this has to be the IP address of the host system (your laptop) as seen from inside the container. Generally, this will just the IP address assigned to the host in the local network. On Linux, you can use  or   to list these addresses. Caveat: if you are running docker in a virtual machine, additional configuration may be necessary.
 *  : adjust this to the port the IDE is listening on (or a port that is configured to forward to the IDE). This should rarely change from xdebug's default, which is 9000.
 *  : the key to use when connecting to the IDE. This has to match the key configured in the IDE. For PhpStorm, the default is.
 *   : the server name to use by PhpStorem to apply path mappings when manually running command line scripts (see PhpStorm documentation ). Caveat: as of November 4 2020, PHP_IDE_CONFIG needs a patch for docker-compse.yaml . And it still didn't quite work for me.
