If someone is able to accomplish what they want using the new build script functionality, why would they want to incur the learning curve, overhead, and complexity of Chef? Don't get me wrong — Chef is a powerful tool and has its place. But for many use cases, it's totally overkill. I think Docker's new build scripts may fit the bill nicely for a sizeable number of folks without needing to figure out how to integrate with an external configuration management system.

Edit: As shykes mentions, the two are really more complementary than overlapping. I'm planning to use Docker's new build scripts to construct pre-built Docker images, which I will subsequently deploy via Ansible (a configuration management tool akin to Chef). Up until today I was building Docker images via Ansible, but now I can handle that within Docker itself, freeing up Ansible to handle tasks better suited to its bailiwick.

Can you post your sample before/after configs? It'd greatly help me understand how Docker can help me, as I can't run it on any of my machines currently (although I just retried it and the "unexpected EOF" error seems to have gone away).
