Recently I started working with GitLab - GitHub self-hosted foss alternative. So far so good, liked the UI, ease of administration, and available functionality (I was on Phabricator previously, and still use it for repo mirroring).
GitLab has GitLab CI (GitLab Continuous Integration) which looks promising (pluggable docker/vm/ds to run code) , but I wondered if someone uses it already and can share scripts for it?
