# once crosscompilation is done, use an actual aarch64 docker image (with a real aarch64 python) to run all the tests under an emulator
# * mount the protobuf root as /work to be able to access the crosscompiled files
# * intentionally use a different image than manylinux2014 so that we don't build and test on the same linux distribution
#   (manylinux_2_24 is debian-based while manylinux2014 is centos-based)
# * to avoid running the process inside docker as root (which can pollute the workspace with files owned by root), we force
#   running under current user's UID and GID. To be able to do that, we need to provide a home directory for the user
#   otherwise the UID would be homeless under the docker container and pip install wouldn't work. For simplicity,
#   we just run map the user's home to a throwaway temporary directory
