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. :-)
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.
Yeah, so? If it's a monstrous undertaking just to get the system to first boot, how does that help anyone? :)
I think that cave is just as useful without init, and I think that most people who want to package something in paludis are not going to be having boot dependencies (on average I would guess at least 50% of apps are not services. I don't have any hard statistics and that number could be high or low.)
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.
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.
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!
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?
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.
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.
What kind of errors? On kernel < 3.8 docker will print a warning because of a known kernel bug. You may or may not hit the bug on 3.5 depending on your hardware configuration. If you do, you'll know: the kernel will panic ;)
Oh, it wasn't a kernel panic, thankfully :) I closed the window now, but, after downloading the image, I got some errors like "improper file permissions" and "bsdtar exiting".
Sorry I can't provide the exact errors, but if I run it it has to download the entire thing again.
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?
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.
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.
