This will install the most up-to-date, stable version of Redis as a dotCloud service.
- Copy the files to the same directory as your dotcloud.yml
- Add the contents of the Redis-Latest dotcloud.yml file to your existing one
- Push your app to dotCloud and voila!
Since this always pulls the most recent, stable version of Redis, it will automatically update whenever you push your app.
