This is a Docker Compose setup for development of Synapse and Matrix appservices.

Checkout Synapse and the IRC bridge appservice:

$ git clone https://github.com/matrix-org/synapse.git synapse/synapse
$ git clone https://github.com/matrix-org/matrix-appservice-irc.git irc-bridge/matrix-appservice-irc

Build the Docker images:

$ docker-compose build

Generate keys::

$ openssl genpkey -out irc-bridge/varlib/passkey.pem -outform PEM -algorithm RSA -pkeyopt rsa_keygen_bits:2048 $ docker-compose run synapse python -m synapse.app.homeserver

-c /etc/matrix-synapse/homeserver.yaml --generate-config --report-stats=no --server-name synapse

Generate the appservice registration file for the IRC bridge [1]:

$ docker-compose run appservice-irc ./bin/matrix-appservice-irc \
  --generate-registration \
  --url http://appservice-irc:9009 \
  --localpart appservice-irc \
  --config /etc/matrix-appservice-irc/config.yaml \
  --file /etc/synapse-appservice-registrations/irc.yaml

Register a Matrix user:

$ docker up synapse # Run in a separate terminal
$ docker-compose run synapse \
  register_new_matrix_user \
  -c /etc/matrix-synapse/homeserver.yaml \
  http://synapse:8008

Follow the prompts and then interrupt (Ctrl+C) the docker up process.

Start the Docker Compose services (you may want to do this in a separate terminal):

$ docker-compose up

Now point your client at https://localhost:8008.
