synapse/docker/complement/SynapseWorkers.Dockerfile

# This dockerfile builds on top of 'docker/Dockerfile-worker' 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

# Download a caddy server to stand in front of nginx and terminate TLS using Complement's
# custom CA.
# We include this near the top of the file in order to cache the result.
