The advantage of adding a port mapping here is that you can connect to the database container from the host, which is handy if you have a graphical MariaDB client such as DBeaver. You can of course also login to the container and run the mysql client on the command line.

			Logging into the container using the host:

			mysql -u app -D app -h 127.0.0.1 -P 3307 -p

			Note: 127.0.0.1 must be used as the host, as MySQL will usually try a socket connection by default if localhost is used (also it may attempt to use ::1, the IPv6 address, which may not work on your setup).

	For port mapping from the host, choose something other than the default port (3306), otherwise you will get a clash if MariaDB is running on the host (which it probably will be on a local development machine).
