Maybe I am biased, but I agree with the other user on here that Ansible is a good solution for keeping the environments the same.

However, if you're feeling brave, you should definitely check out OpenShift (community version at http://openshift.org). OpenShift is basically Kubernetes with a bunch of cool stuff added, one especially useful feature is source-to-image.

It pulls your code from a scm repo and finds a builder image (or you can choose one) and it will build the docker image for you. You can have it pull whenever there is new code and rebuild the image and deploy if you want.

On top of that you get lots of cool docker orchestration features.
