Wow! Did not expect this to show up on HN before actual release! (I work at dotCloud). We're still polishing a few rough edges. If you want early access add your github ID to this thread and we'll add you right away!

I am working with cpra-lcoffe,and looking forward to testing this out. https://github.com/cpr-mbelarbi

Earlier quoted context omitted.

It's not that it's any different, it's that it's standardized . The idea is that a Docker container would be portable between different PaaS hosts (and from your own staging environment to those hosts!) without rebuilding, because they'd all be using the "Docker standard for deployment." A PaaS host saying they supported Docker would imply that they'd be using, for example, SquashFS for container format, AuFS instead…

Doesn't a standard involve, you know, standards? AFAIK a product name is not a standard. What if the namespace changes? What if AuFS changes? What if LXC changes? Independently or all together? ABI changes? Version changes? Feature changes? Are all the licenses compatible? Will it ever support platforms other than just certain versions of Linux? Or languages other than Go? I don't see a standard. I see marketing for…

The best standards come from ratifying practice, not dictat.

fyi, aufs which is the union mount filesystem required by docker (and cloud foundry warden), is not well supported on rhel, centos, and other linux distros, seems mainly support for ubuntu.

More than this, Ubuntu are trying to remove it from their distribution in favour of overlayfs [0]. As mentioned there, the reason is that aufs is not and will not be part of the mainline kernel. Precise 12.04 was going to be without AUFS, but some issues cropped up, keeping it around.

It now looks like overlayfs will make it into the 3.10 mainline kernel [1], so it may be a better choice in the future. I think that the Under the hood stuff on docker's page are implementation details that can change, so a switch to overlayfs when that becomes more suitable could be possible. (Confirmation from the dotClouders present would be apprecaited.)
