This has come up in the German forum, but might be interesting for all.

During installation, that is running installer.pl via the WebGUI, one can set up a database that is not running under Docker. In that caste the MariaDB database, which is started per default by Docker compose, is of no use. The startup can be suppressed by scaling the number of instances to 0:

docker-compose up --detach --scale db=0
