# Dockerfile to build the matrixdotorg/synapse docker images.
#
# Note that it uses features which are only available in BuildKit - see
# https://docs.docker.com/go/buildkit/ for more information.
#
# To build the image, run `docker build` command from the root of the
# synapse repository:
#
# DOCKER_BUILDKIT=1 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_BUILDKIT=1 docker build -f docker/Dockerfile --build-arg PYTHON_VERSION=3.9 .
#
ARG PYTHON_VERSION=3.8

# https://github.com/moby/buildkit/blob/master/frontend/dockerfile/docs/syntax.md#build-mounts-run---mount.
# Here we use it to set up a cache for apt, to improve rebuild speeds on
# slow connections.
