Docker 0.7 Runs On All Linux Distributions 88
rjmarvin writes "Docker 0.7 was released today, with 7 major new features including support to run on all Linux distributions. No longer capable solely on running on Debian and Ubuntu Linux, Docker 0.7 adds support for distributions such as Red Hat, SUSE, Gentoo and Arch. From the announcement: 'A key feature of Docker is the ability to create many copies of the same base filesystem almost instantly. Under the hood Docker makes heavy use of AUFS by Junjiro R. Okajima as a copy-on-write storage mechanism. AUFS is an amazing piece of software and at this point it’s safe to say that it has safely copied billions of containers over the last few years, a great many of them in critical production environments. Unfortunately, AUFS is not part of the standard linux kernel and it’s unclear when it will be merged. This has prevented docker from being available on all Linux systems. Docker 0.7 solves this problem by introducing a storage driver API, and shipping with several drivers. Currently 3 drivers are available: AUFS, VFS (which uses simple directories and copy) and DEVICEMAPPER, developed in collaboration with Alex Larsson and the talented team at Red Hat, which uses an advanced variation of LVM snapshots to implement copy-on-write. An experimental BTRFS driver is also being developed, with even more coming soon: ZFS, Gluster, Ceph, etc. When the docker daemon is started it will automatically select a suitable driver depending on its capabilities.'"

Linux Containers are one of the greatest things to come to linux in the last ten years. Looking at the comments posted here already it's no wonder my pleas for time to work in something like this never got any traction. Docker's going to be a game changer.
All you managers that didn't think LXC was relevant, look at Docker and suck it. Could have been you dumbass.

Even after reading it, I've got no fucking idea what it does! Their "read more" page just shits out a whole load of buzzwords.
It's container-style virtualization. Which has been around forever. Even on Linux.
But apparently, everything old is new again sometime, and this is the time.
Granted, it's probably about time, after all, since Docker doesn't appear to suck complete ass and isn't commercial (either of which has largely been the main problem with previous Linux containerization).
