> So git is to github as (chroot/cgroups/unionfs) is to docker et all? You could do docker-alike runtime things with lxc and e.g. squashfs filesystems. That is IMHO a good signal to say it's not the tech. I see it more as developer workflows. Github looked at git and LKML working model and put that into a centralized UI. The revolution was individual contribution (not teams) and personal repositories. (Does anyone remember the other scm hosting tools before? I remember running some open source sorceforge alike thing) Docker took all the pieces before you could run a container and made those easy to achieve (building, sharing, pulling, ...). That's developer workflows.
