You're right, it's not quite that easy yet, but it probably will be eventually. Docker just provides the building blocks. SaaS providers like Docker Cloud will get better and continue to abstract complexity away until it really is that easy.

You don't need to use Rancher if you're just running one app. If that's all you need to do, then it could be as simple as running docker-compose on a linux server and mounting the certs into the nginx container as a host volume (https://github.com/jwilder/nginx-proxy). This is a fine approach until you want to split your containers across several hosts (redundancy or scaling) and you have several apps to worry about.
