Docker: copy postgres from base image (#13279)
When building the docker images for complement testing, copy a preinstalled
complement over from a base image, rather than apt installing it. This avoids
network traffic and is much faster.

# This dockerfile builds on top of 'docker/Dockerfile-workers' in matrix-org/synapse
# by including a built-in postgres instance, as well as setting up the homeserver so
# that it is ready for testing via Complement.
#
# Instructions for building this image from those it depends on is detailed in this guide:
# https://github.com/matrix-org/synapse/blob/develop/docker/README-testing.md#testing-with-postgresql-and-single-or-multi-process-synapse
ARG SYNAPSE_VERSION=latest
# first of all, we create a base image with a postgres server and database,
# which we can copy into the target image. For repeated rebuilds, this is
# much faster than apt installing postgres each time.
#
# This trick only works because (a) the Synapse image happens to have all the
# shared libraries that postgres wants, (b) we use a postgres image based on
# the same debian version as Synapse's docker image (so the versions of the
# shared libraries match).
FROM postgres:13-bullseye AS postgres_base
# initialise the database cluster in /var/lib/postgresql
RUN gosu postgres initdb --locale=C --encoding=UTF-8 --auth-host password
# Configure a password and create a database for Synapse
RUN echo "ALTER USER postgres PASSWORD 'somesecret'" | gosu postgres postgres --single
RUN echo "CREATE DATABASE synapse" | gosu postgres postgres --single
# now build the final image, based on the Synapse image.
