+### MySQL access from host
+
+You can forward the MySQL/MariaDB port to your host by adding the lines
+```
+ports:
+    - "3306:3306"
+```
+To the `mysql` or `mariadb` section of the LaraDock `docker-compose.yml` or in your [environment specific Compose](https://docs.docker.com/compose/extends/) file.
+
+The MySQL port is not forwarded by default because Docker will automatically publish the port on the host, which is quite insecure, unless specifically told not to. To learn more about how Docker publishes ports, please read [this excellent post on the subject](https://fralef.me/docker-and-iptables.html).
