nodejs docker on SCALE?

[justinception]

I'm trying to setup a docker container for running a node js app (that I wrote). I'm a bit of a newbie when it comes to docker, but from what I've read all I need to do is "Launch docker image" and enter the image name from the docker repo. In this case: https://hub.docker.com/_/node My config looks like this:

After that the UI just says deploying forever. I must be missing something obvious, any ideas?
