Gentoo
Installing Docker on Gentoo Linux can be accomplished using one of two methods. The first and best way if you're looking for a stable experience is to use the official app-emulation/docker package directly in the portage tree.
If you're looking for a -bin ebuild, a live ebuild, or bleeding edge
ebuild changes/fixes, the second installation method is to use the
overlay provided at
https://github.com/tianon/docker-overlay
which can be added using app-portage/layman. The most accurate and
up-to-date documentation for properly installing and using the overlay
can be found in the overlay
README.
Note that sometimes there is a disparity between the latest version and what's in the overlay, and between the latest version in the overlay and what's in the portage tree. Please be patient, and the latest version should propagate shortly.
Installation
The package should properly pull in all the necessary dependencies and prompt for all necessary kernel options. The ebuilds for 0.7+ include use flags to pull in the proper dependencies of the major storage drivers, with the "device-mapper" use flag being enabled by default, since that is the simplest installation path.
$ sudo emerge -av app-emulation/docker
If any issues arise from this ebuild or the resulting binary, including and especially missing kernel configuration flags and/or dependencies, open an issue on the docker-overlay repository or ping tianon directly in the #docker IRC channel on the freenode network.
Other use flags are described in detail on tianon's blog.
Starting Docker
Ensure that you are running a kernel that includes all the necessary modules and/or configuration for LXC (and optionally for device-mapper and/or AUFS, depending on the storage driver you`ve decided to use).
