synapse/docker/Dockerfile

# Dockerfile to build the matrixdotorg/synapse docker images.
#
# To build the image, run `docker build` command from the root of the
# synapse repository:
#
#    docker build -f docker/Dockerfile .
#
# There is an optional PYTHON_VERSION build argument which sets the
# version of python to build against: for example:
#
#    docker build -f docker/Dockerfile --build-arg PYTHON_VERSION=3.6 .
#

ARG PYTHON_VERSION=3.8
