docker-registry: Add a Gentoo-based docker-registry
The requirements are installed using Portage, because that handles
non-Python requirements gracefully, and caches all the source tarballs
for later use (e.g. if PyPI is down). Note with the
20140206
snapshot, this installs dev-python/gevent-1.0_rc3, which is based on
libev not libevent like the pre 1.0 gevents [1]:
New version of gevent uses libev and c-ares rather than libevent and
includes all the dependencies in the release tarball.
You may have to bump your gevent requirements (docker-registry's
requirements.txt currently pins it at 0.13.8) or install
dev-libs/libevent if you want to run the tox test suite.
Bugsnag doesn't have a Gentoo package, so I don't install it. That
means you won't be able to use Bugsnag with this image (unless you
install it yourself), and you'll want a version of docker-registry
that includes
e253550 (Merge pull request #241 from
wking/optional-bugsnag, 2014-02-11).

build.sh: Use DOCKER to allow local command overrides
On Debian, the binary is installed as docker.io [1] to avoid confusion
with the existing window manager docker package [2].
While you can override DOCKER, it would be nice if we just worked out
of the box for everyone. Use 'command -v' [3] and the temporary
DOCKER_IO to setup the following chain:
1. If DOCKER is already set (e.g., by the user) use it.
2. Fall back to docker.io, if we find it in the PATH.
3. Fall back to docker.
The logic is that if docker.io exists, it's almost certainly what we
want. If docker exists in the path, it's more ambiguous.

nginx-proxy/vhost-template.conf: Set X-Forwarded-Host
Since v1.5, Django cares about the requested Host (or
X-Forwarded-Host) [1], so we need to pass that information through.

the appropriate hostname instead of your Docker container's IP.

nginx-proxy: Add an Nginx proxy image
I've got a bunch of HTTP server images, but I need a single proxy
container that supports SNI to expose them to the world. This
container can link to a colleciton of HTTP-serving containers and
proxy them under arbitrary hostnames using user-supplied, per-host
certificates and keys.
env and sed are both in POSIX 2013 [1,2], and the:
eval A=\$$B
variable indirection is because POSIX [3] doesn't support Bash's
indirect expansion "A=${!B}". The 'tcp' -> 'http' replacement maps
Docker's tcp:://${IP}:${PORT} addresses to http://${IP}:${PORT} for
use in the Nginx config.
envsubst is in gettext [4] and not in POSIX [5], so it may be slightly
less portable. However, envsubst and gettext are in Gentoo's x86 and
amd64 stage1s, our Gentoo-based images will have it.

nginx/Dockerfile.template: Change default hostname to _
From the docs [1]:
In catch-all server examples the strange name “_” can be seen:
server {

There is nothing special about this name, it is just one of a myriad
of invalid domain names which never intersect with any real name.

public server.
