Looking at Rancher, what is the performance like? I guess my main question, is everything deployed in Rancher docker in docker? After reading http://jpetazzo.github.io/2015/09/03/do-not-use-docker-in-docker-for-ci/ I trying to stay away from that idea. It looks like the Rancher CI pipeline with Docker/Jenkins is docker in docker, but what about the rest? If i setup a docker-compose or deploy something from their catalog, is it all docker in docker? I've read through their documentation and this simple question has still just flown over my head. Any guidance would be much appreciated.
Thank you
