wking/ngircd-trimmed
20140717 98daec1a09c5 16 hours ago 340.9 MB
so about 20% of the trimmed image is a useless old Python version. We
could shrink the trimmed image even more by removing Portage and
Python 3, but that requires some external-to-Portage hackery. This is
easy to do, and folks who *do* need Python 2 can easily adjust their
PYTHON_TARGETS, PYTHON_SINGLE_TARGET, eselected Python, and re-emerge.
We only need to emerge @system, because @world is still empty at this

There are some special runlevels that you should be aware of:

You should not call any of these runlevels yourself. Instead you
should use init(8) and shutdown(8) and let them call these special
runlevels.

out how to get the logs out via 'docker logs'. I tried a number of
things, including
RUN sed -i 's|^\([^#].*/sbin/agetty.*\)|#\1|' /etc/inittab
RUN echo 'log1:12345:respawn:/usr/bin/tail -F /var/log/messages >/dev/console' >> /etc/inittab
but none of my attempts along those lines worked.
You could work around this by volume-mounting a host directory to the
container's /var/log, or by configuring syslog-ng to forward logs to a
remote destination with something like:
RUN sed -i 's/^\(destination messages\).*;$/\1 { tcp("logs.example.net" port(514) };/' /etc/syslog-ng/syslog-ng.conf
But we don't have a central syslog instance to forward to, and I like
'docker logs' ;).
So that nixed the /sbin/init approach, and I started looking at signal
trapping in a shell script [1]. When I tried to use 'shutdown -h now'
in place of 'rc shutdown', I got log messages like:
Mar 12 18:29:14
f50a7b4bd8c9 logger: trapped SIGTERM, shutting down
Mar 12 18:29:14
f50a7b4bd8c9 shutdown[272]: shutting down for system halt
shutdown: /dev/initctl: No such file or directory
init: /dev/initctl: No such file or directory
because /sbin/init (which creates /dev/initctl) was not running).
Using 'rc shutdown' directly avoids that problem.
Also in this commit:
* Add an initial ^ to the console_all sed line, which just makes
explicit the fact that I'm matching from the beginning of the line.
* Enable boot logging to /var/log/rc.log, in case someone actually
does run /sbin/init.

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 {
listen 80 default_server;
server_name _;
return 444;
}
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.
Still, an invalid domain name makes more sense than 'localhost' for a
public server.

postgresql: Declare /var/lib/postgresql a VOLUME
Avoid the hassle of maintaining a host-mounted volume by letting
Docker handle the volume maintenance ;). We need to declare the
VOLUME *after* filling it with content (with 'emerge --config'),
otherwise ownership and permissions on the empty volume are lost
[1,2,3], and future RUN commands die due to:
initdb: could not access directory "/var/lib/postgresql/9.3/data": Permission denied

Use envsubst instead of sed to parse Dockerfile.template
Convert everything in one pass, instead of taking a separate pass for
each variable. Thanks to aluedeke for mentioning envsubst on #docker;
I hadn't heard of it before. It's distributed as part of gettext [1],
and not in POSIX [2], so it may be slightly less portable. However,
envsubst and gettext are in Gentoo's x86 and amd64 stage1s, so it
can't be *that* uncommon ;).

memcached: Add a Memcached image
The 10MB of overhead memory were estimated from this output in a
running memcached container:
# ps aux

Less Bash and ps, that's 1112 + 3620 + 804 = 5.5MB of resident memory,
so 10MB seemed like a safe buffer.
