Answer 1

If you're only going to do this once on your host, and assuming they are TCP ports, you can 'publish' them like this:

sudo docker run -p 6633:6633 -p 8080:8080 my_image

The -p option is described more at the top of this page: http://docs.docker.com/userguide/dockerlinks/

Answer 2

Are you using dockerfile? In the dockerfile, you could simply add this:

EXPOSE 6633
