Restrict published port to a specific container with Docker

I have two Docker images :

I run two containers using these images, linking mysql with tomcat :

docker run -itd -p 3306:3306 --name mysql mysql
docker run -itd -p 8080:8080 --link mysql:mysql --name tomcat tomcat

When I do that, tomcat communication with mysql works fine, and my tomcat and mysql containers are available on the server host, respectively on ports 8080 and 3306.

Now I would like the port 3306 to be closed on the server host and only available for the tomcat container. How can I do that?

In that case you can simply skip the -p parameter like:

docker run -itd --name mysql mysql
docker run -itd -p 8080:8080 --link mysql:mysql --name tomcat tomcat
