The problem is that bazel is happily copying the darwin compiled lib for grpc, instead of one compatible with your container's platform. Take a look here how to download the wheels that will work for you: bazelbuild/rules_python#773 (comment)

You will probably want to use the multilinux_2_17 wheels.
