10 years agoportage: Add a Portage-volume-exporting image

portage: Add a Portage-volume-exporting image

This builds the Portage snapshot into a stand-alone volume, which can
be mounted using -volumes-from.  There's currently no
Dockerfile-supported way to mount this for builds, so gentoo-portage
still goes the emerge-webrsync route.

We need something to fill the role of /bin/sh in the Portage-snapshot
container, so I'm using the /bin/busybox from the 'gentoo' image.  As
of 2013-12-12, it's:

  sys-apps/busybox-1.21.0
    USE="ipv6 pam static -livecd -make-symlinks -math -mdev -savedconfig
         (-selinux) -sep-usr -syslog -systemd"

postgresql: Add PostgreSQL container instructions (Dockerfile and README)

The $(echo /etc/postgresql*/postgresql.conf) crazyness in the
Dockerfile is because Docker chokes on:

  RUN echo host  all  all  0.0.0.0/0  trust >> /etc/postgresql*/pg_hba.conf

raising:

  /bin/sh: /etc/postgresql*/pg_hba.conf: No such file or directory

I'm not sure why it's not expanding the glob.  Perhaps Docker is
quoting redirection targets?  In any case, the $(echo ...) form works,
so that's what I'm going with for now.
