I see that you exposed port 3000 in reply to one of the issues. Not sure why it won't work for me. I run cloud9 using dokku. So the editor runs on something like cloud9.mydomain.com. Have tried exposing 8080,8081,8082 in the dockerfile. Dokku exposes them. But i cannot get to cloud9.mydomain.com:3000 or any other port.

Any ideas? What am i missing?
