Concourse really seems like a nicer Go.CD, in terms of how pipelines, jobs and resources work. I'm quite interested to see how it can work for a fully Docker-based workflow (each git repo has a Dockerfile in the root, that we want to rebuild whenever the master branch receives a new commit. Then we run the image in a container, execute our tests, then if the pass export the Docker image and pass it on to the staging server, start up a new container and shut down the old one).
