setup docker for mediawiki following official compose. wait until it inits (give it a few minutes). i use a reverse proxy to access the container. if you do, edit hte reverse proxy config: login to mediawiki, and go through the steps to configure it. check the db, to make sure you have something there... I check the users table. if the user is in there, the install completed successfully. go to the install page again, and you should be able to download localsettings.php Troubleshooting: my wiki db is empty after setup! if your db fails to init, you can always create the db after. docker cp mediawiki:/var/www/html/maintenance/tables.sql . docker cp tables.sql mediawiki_db:/. then init into the db and import the sql. That tables.sql command will create the db. Note that you will need to manually create the user but there is also some scripts in maintenance, as well as documentation on mediawiki regarding that.
