Constraints for Swarm scheduling are defined as an **environment** option, according to the example in the section *Manual scheduling*, and not as a **label** option

In this example, database.yml uses the default value of `postgres` for the `database` key.
The database postgres is normally not used for user data, but for administrative purposes. This means people following this example will not be able to drop the database, and in general it's just not a great idea.
- Some wording and formatting tweaks
- Use Python 3.4, because it's 2016
- Use Alpine-based images for faster downloads and less disk space usage
- Use the list form of `CMD` in the Dockerfile, so it's not wrapped in
sh
- Remove the `depends_on` from `docker-compose.yml`, as it's not really
needed - the web app connects to Redis when it's visited, not on
startup
- Add a section on updating the app and seeing the changes, because
that's the point of mounting the code in!
- Add a note about `docker-compose down`
