This combines the advantages of Device Mapper (granularity) and AUFS/overlay (page cache re-use), and doesn't require new kernel code. Promising!

The comparison with systemd is unfair. Docker wants to be "batteries included, but swappable/removable". If you don't like host management, orchestration, build, etc., you can disable that specific component and put anot

Docker can play with or without Chef/Puppet/Salt/Ansible/etc.: - you can use configuration management tools to author Docker images; - you can use configuration management tools to deploy Docker (and start Docker contain

Actually, Docker doesn't always have docker0; you can configure it to use a different bridge. On my setup, for instance, I use br0 and share the same bridge for containers and VMs.

FWIW, boot2docker became my favorite all-purpose, ready-to-run, ridiculously-small-and-therefore-insanely-fast-to-download VM image. It's faster to download it (it's 25 MB) and start it with qemu, than to go through the clicky-poi

I don't know yet what will happen for Windows, but an upcoming version of Docker will run on OS X. (I say "upcoming" because I know some core maintainers have OS X support in their local branches, so it's just a matter

"A few systems that support LXC", that's actually most modern Linux systems now. Anything with a 3.8 kernel is game.

Indeed; for the lucky ones around here with a bare metal Linux box, just substitute kvm instead and ROCK ON!

I assume entire responsibility for this; and the associated confusion which ensues when doing e.g. "curl get.docker.io/blah | sh" :)

This is an update to the "classical" Docker presentation. It includes some details about integration with configuration management systems, and the new "-name" and "-link" features.

In the Docker issues, also look for the "easyfix" tag. We try to set it for issues that are hopefully actionable for people with a moderate knowledge of Docker and/or Go.

There is a trade-off between "running anywhere" and "running mostly anywhere". I.e. going from 99% to 99.99% :-) The server-side component only runs on Linux for now, and while it's supported only on x86_64, people

Thanks! godep is definitely cool. But it's a bit sad that it has to be an add-on. Don't get me wrong -- it's a great thing that go gives us a good build system, a good test system, a good dependency system, etc. But if we end

I don't understand what this means; can you elaborate? Since the attachment for an AOE drive is Ethernet, the drive controller is just an Ethernet NIC...

Yup; there are lots of Docker images available at http://index.docker.io/; and more interesting features are on the way (trusted images, automated builds...) Also, the Docker workflow is appealing to (at least) some people;

Among the tons of new features, Havana has native support for Docker containers (as a Nova driver). This means at least three big things: - when testing OpenStack workloads, you can spin up containers instead of VMs, and boot environments i

All this stuff also applies if you don't want to use LXC, Docker, or any kind of container. You can put processes in control groups, and get all those metrics as well. This is one of the reasons why OpenVZ was initially rejected from b
