Docker 0.7 Runs On All Linux Distributions
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.'"
DOes this have something to do with boats? I hate boats, why is Slashdort posting news about boats? I mean, I really hate boats. Don't get me started, Slashdort.

...now what the fuck is a docker?

If you don't understand any of my sayings, come to me in private and I shall take you in my German mouth.
Similar to OSX bundles, or to Application Virtualization (ThinApp) on Windows.
Combined with a universal overlay filesystem, this is a great thing.
"Flyin' in just a sweet place,
Never been known to fail..."
Does it run on Windows?
If you had to guess what a piece of software called "Docker" did, what would you think?
systemd is Roko's Basilisk.
Looks like someone figured out how to put a fancy spin on chroot. Sweet.
I shouldn't have to go look it up.

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.
Samsung took back my unlocked bootloader because Google wants me to rent movies. They're both evil.
Sure doesn't seem to want to run on my Yggdrasil box.

What the hell does it do?
How is it better than ZFS snapshots?
A zero-point-something release is newsworthy? Hear ye, hear ye, alpha quality shite runs on all Linux distributions!
Aside from the fact we should not have to look up some esoteric item to see what the hell we are talking about, and if we care...
For those in the know: is this something like thinapp or cameyo for Linux that is truly virtual, or is it more of a portable jail? Not that i cant read, but i see the words 'virtual' misused so often it shard to tell without digging too deep. If it is truly virtualized that is cool, if its yet anther jail/chroot management tool, *yawn*

The main question is - what is a Linux container, and why do I care about it? I don't care about some awfully named Linux program that has been ported to other distros. Why call it "Docker" if it has nothing to do with men's slacks or the icon dock at the bottom of the screen? Asking what Docker is results in a blizzard of acronyms and terms that only matter to someone who already knows what it is. The real question is, what is a Linux container? Why do people use them? Anyone talking about Linux containers needs to have the 30-second "elevator pitch" to explain why they're great and why they're going to rule the world. Otherwise, what's the point?
Just something simple like this: "Docker is a utility for Linux containers, an exciting technology for embedding Linux in cargo containers to create smart cargo containers capable of telling the cargomaster their temperature, weight, time at sea, and destination, to allow more efficient ship loading and cargo routing, which will save shipping firms millions of dollars each month."
How does this differ from what OpenShift is doing?
it is an important feature of dockers :p
Never antropomorphize computers, they do not like that
How is MATE better than GNOME 3.8 in Classic mode?
Can Docker be used for distro-neutral application packaging on Linux? (May be a silly question, but I'm still not sure, even after reading TFA and comments.)
Yes, containers are like jail/chroot. But containers in more recent Linux kernels are now mature enough to almost do all things Solaris Zones does. Like proper security and with use of the http://criu.org/ project, you can also do live-migration in many cases.
New things are always on the horizon
Seriously, this is what Slashdot has come to? Despite multiple attempts to indicate what Docker is and why it represents an impressive technological feat, a chorus of "WTF is Docker??? hurr hurr" resounds? Take a moment & check it out, for Pete's sake. I think I'm done with Slashdot if this is what the discussion has descended to.
