Ominbus Docker: Can not change external URL

I’m using the latest Omnibus Docker container and things were going quite well. I imported a repo from an external source and it looked fine, except that the clone URL had the containerID in it:

 http://7469dc6b9306/csc/myRepo.git

When I looked at the Project settings, however, the correct URL was displayed including the alternate port that I have the gitlab container mapped to on the host. Like this:

http://myhost.net:9080/csc/myRepo.git

And I confirmed that the repo was clonable from that URL.

So I tried changing this setting in gitlab.rb:

external_url 'http://7469dc6b9306'

to

external_url  'http://myhost.net:9080'

but then gitlab wouldn’t even start. Its kind of minor since we’re a small team and I can just let the other folks know, but I would like to get that right if for only my own sanity.

Thanks,
