# syntax=docker/dockerfile:1

# 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:

# 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).
