I haven't tested docker on Ubuntu 10.04. But you can probably expect the following: 1) You will need to boot a 3.8+ kernel, which is definitely possible but probably not available as a 10.04 package (unless someone has backported it). 2) Docker has a few userland dependencies as well. Most of them are extremely stable (tar, iptables, ip). But the lxc userland scripts have changed a lot in the last couple years. Docker is known to work with version 0.8, and that version might not be available in Ubuntu 10.04. In short, I expect that docker will not work out of the box on a vanilla 10.04 system, but it can be made to work with a fairly small amount of customization. If you're interested in trying it out, feel free to join the #docker IRC channel on Freenode. We'll help you out!
