+
+Expose port 3306 inside the container on port 3306 on ALL local host interfaces. In order to bind to only one interface, you may specify the host's IP address as `([<host_interface>:[host_port]])|(<host_port>):<container_port>[/udp]` as defined in the [docker port binding documentation](http://docs.docker.com/userguide/dockerlinks/)

+```
+volumes:

+     - ./conf/mariadb-conf.d:/etc/mysql/conf.d
+```
+Expose a directory inside the host to the container.
+
+#### links:
+
+```
+links:
+      - redis
+      - mariadb

+
+Links another container to the current container. This will add `--link postgres:postgres`
+to the options when running the container.

+	Express dependency between services, which has two effects:
+
+	1. docker-compose up will start services in dependency order. In the following example, db and redis will be started before web.
+
+	2. docker-compose up SERVICE will automatically include SERVICE’s dependencies. In the following example, docker-compose up web will also create and start db and redis.
