- # 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:
- # 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.
- FROM matrixdotorg/synapse-workers:$SYNAPSE_VERSION
- # copy the postgres installation over from the image we built above
- RUN adduser --system --uid 999 postgres --home /var/lib/postgresql

- # Extend the shared homeserver config to disable rate-limiting,
- # set Complement's static shared secret, enable registration, amongst other
- # tweaks to get Synapse ready for testing.
- # To do this, we copy the old template out of the way and then include it
- # with Jinja2.
