"you can now choose between Debian, Ubuntu, Centos, Gentoo, Arch Linux and Busybox as the base layer for building your containers."

Now this is great. Using this instead of VMs is a win.

I will be pleased when Exherbo is added to the list.

(Although 90% of the fun I had with exherbo was struggling to get the systemd in place, and that's nullified in a docker system since docker replaces init to run a single process _other than_ init)

EDIT: I guess now I'm volunteering to try and put Exherbo on the list.

zokier• 13 years ago

I thought that Exherbo was very diy-oriented distro with with the assumption that users will package their own packages if the need arises.

Does anyone know if Docker runs on a 32-bit ubuntu host?

shykes12• 13 years ago

Not yet... We're sticking to x86_64 for now to maintain focus. Once we've nailed the experience on 1 arch we will extend to more.

auxbuss• 13 years ago

Awesome work, Solomon & team. Just to add that I have a bunch of 32-bit that this I would love to use this on. Looks like a potential game-changer, imo. Thanks so much for sharing.

So, what is Docker and why should we care about a 0.x release? Yes, I looked at the link and no, I was not much the wiser, something to do with virtualization perhaps?

shykes12• 13 years ago

If you click on the project name at the top of the page, you'll find a README which starts with:

Docker complements LXC with a high-level API which operates at the process level. It runs unix processes with strong guarantees of isolation and repeatability across servers.

Docker is a great building block for automating distributed systems: large-scale web deployments, database clusters, continuous deployment systems, private PaaS, service-oriented architectures, etc.

andrewflnr• 13 years ago

For a lot of people that's not terribly helpful. Before I heard of Docker I had never heard of LXC.

Maybe, "Docker is a system for creating and deploying self-contained application packages for Linux," except I'm pretty sure "application package" is the wrong phrase. But that's the gist of why it's interesting, IMHO.

Korvin• 13 years ago

It looks to be similar to freeBSD jails

fss• 13 years ago

Actually, Docker is like a manager of FreeBSD jails :-) LXC is like FreeBSD jailing.

You guys have fixed every single frustration or oddity I experienced when playing with docker just a week or two ago:

    * localhost access.
    * re-attaching to terminal.
    * set your own port.

Brilliant work guys!

shykes12• 13 years ago

Thanks :) Make sure to +1 requests that you want to see next, so we can prioritize accordingly!

bryanh2• 13 years ago

Just did on the REST API suggestion! I noticed you mentioned a half-baked proof of concept, if you decide to publish the branch I wouldn't mind hacking on it. :-)

sylvinus• 13 years ago

Congrats!

We couldn't be happier to have Solomon as a speaker at our conference in Paris on June 7: http://dotscale.eu

See you there :-)

Can I use this on arch without rebuilding a new kernel yet?

shykes12• 13 years ago

I haven't tried personally, but here are the latest instructions: http://docs.docker.io/en/latest/installation/archlinux/

StavrosK4• 13 years ago

Hmm, I want to try it out now, but checking out the repo gives me a bunch of files. Why do I need Vagrant/VirtualBox for this? I thought the whole point was that I would use it to replace VBox?

shykes12• 13 years ago

You don't need virtualbox or vagrant, but you do need a Linux machine. So if you are running a Mac or Windows machine, Virtualbox/vagrant is a convenient way to get a linux machine up and running.

Docker itself is just one binary. Here are instructions to get started: http://docker.io/gettingstarted

StavrosK4• 13 years ago

Thanks, I realized that later (I just cded into the dir and built it). I got some errors after downloading the image, however. I assume it's because I'm on the 3.5 kernel rather than 3.8.

shykes12• 13 years ago

Hey everyone, as usual thanks for the great feedback. If you want to keep talking I encourage you to drop by our IRC channel - #docker@freenode.

SEJeff• 13 years ago

Is there ever a chance to not require aufs? I'd like to use docker on Fedora and maybe even CentOS for fun (managing various containers for some open sauce stuff I maintain), but would prefer to do it without needing aufs.

shykes12• 13 years ago

We're seriously looking into btrfs/zfs/qcow etc. Not 100% sure how to get multi-layered mounts and easy export of changes as tarballs.. Hard to beat aufs on those fronts. But we need to make it easier to install on redhat-land, one way or the other.

I encourage you to +1 the relevant issues so we can prioritize!

pepijndevos• 13 years ago

I've been thinking about "dockerizing" my application. How do I "get in touch" about that?

shykes12• 13 years ago

You can join the irc channel, or send a message on the google group, or create an issue on github to describe your use case and ask for advice, or even just email me at solomon@dotcloud.com. Or you if you happen to be in San Francisco on May 2nd, you can drop by the dotCloud HQ for the Docker hack day.
