# 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=3.10 .
|
|
#
|
|
|
|
# Irritatingly, there is no blessed guide on how to distribute an application with its
|
|
# poetry-managed environment in a docker image. We have opted for
|
|
# `poetry export | pip install -r /dev/stdin`, but there are known bugs in
|
|
# in `poetry export` whose fixes (scheduled for poetry 1.2) have yet to be released.
|
|
# In case we get bitten by those bugs in the future, the recommendations here might
|
|
# be useful:
