I just completed a bit of a Docker POC at Flock, and put together a bit of a wiki page on it. Not a whole ton there right now, but as we look towards more nimble deployment mechanisms, Docker might be something worth looking at. I hacked together a container with pastebin (sticky-notes) in it, and a database external to the container. It didn't take more than a few hours of work going from an Ansible playbook to a working container. Let me know if anyone has questions or comments on the work so far. Currently it's just on a transient cloud instance, and there are a lot of things to think about (some of which I noted on the wiki page) before we think about moving stuff somewhere more permanent. There's a mention of something on the wiki page called Custodia. This is a mechanism for securely provisioning, storing, distributing, and auditing access to secret data. I wasn't able to find much on the Internet, but Simo gave a talk on it at Flock if you went there :) Anyhow, the wiki page is https://fedoraproject.org/wiki/Infrastructure_Docker_POC -Jon
