Just a warning: I have recently had issues with dev mode because it does
not do a pip install, but mounts the source code into the site-packages
/<python>/<package> directory, if there are new source files these will not
be included in the package's file manifest. Also this won't affect any
files outside of site-packages/<python>/<package>. I just raised a bug [1]
on this.

What I often do when developing in a tight-ish loop on a single host is
something like this:

docker exec -it <container> pip install -e git+https://<repo>#<egg>
docker restart <container>

You have to be careful, since if the service doesn't start, the container
will fail to start, and docker exec won't work. At that point you need to
delete the container and redeploy.
