 ## Running the container
 
+### Configuration
+
+#### Port binding
+
+By default, the database running within the container will listen on port 3306. You can expose the container port 3306 to the host port 3306 with the `-p 3306:3306` argument to `docker run`, like the command below:
+
+```console
+$ docker run --name some-mariadb -p 3306:3306 mariadb:latest
+```
