Just ran into this same issue, and the initial fix was to change the name of the service in docker-compose.yml.

This worked, but the reason it worked is because Docker-compose caches the build & ties it to the service name. Every docker-compose up after the first one just uses what it built before, so any changes you make to the Dockerfile, or that section of the docker-compose.yml are basically ignored.

When you (and I) changed the service name, it triggered a new build since that service name hasn't been tagged before.

The real solution is to do a: docker-compose build to rebuild the image (followed by a docker-compose up). Their documentation doesn't really emphasize this issue.
