"Container name cannot be empty" on new project initiation

[mattsjohnston]

I'm on MacOS Sierra, and trying to use gatsd on a new project.

When I run ./gatsd/new I'm getting the following error after it seems to complete a successful Docker build:

Initializing project.
Container name cannot be empty
docker: invalid publish opts format (should be name=value but got ':').
See 'docker run --help'.
