Description

When trying to build a docker image on a 32 bit raspbian environment, the build fails because it cannot find a proper rust compiler for building the cryptography package. Note that this happens in the initial "poetry" stage, not the second one where the relevent dependencies are in fact installed using apt.

The command used was

DOCKER_BUILDKIT=1 docker build --pull --build-arg PYTHON_VERSION=3.9 -f docker/Dockerfile -t synapse:v1.63.1 -t synapse:latest .

and the output scrolled of of my screen unfortunately.

Steps to reproduce

• checkout git
• try to run a build: DOCKER_BUILDKIT=1 docker build --pull --build-arg PYTHON_VERSION=3.9 -f docker/Dockerfile -t synapse:v1.63.1 -t synapse:latest .
