Hey everyone! I'm trying to setup pants for our monorepo with python microservices. All seems to be good besides setting up the packaging to docker image. My BUILD contains:

# Define the source code target for FastAPI application
python_sources(
    name = "fastapi_src",
    dependencies = [
        ":reqs",
    ],
    sources = ["**/*.py"],
)

# Define the application dependencies
python_requirements(
    name = "reqs",
)

# Binary to generate application
pex_binary(
    name = "fastapi_binary",
    dependencies = [
        ":fastapi_src",
    ],
    entry_point = "app.py",
    restartable = True,
)

docker_image(
    name = "fastapi_service_docker",
    dependencies = [":fastapi_binary"],
)

My Dockerfile is:

FROM public.ecr.aws/docker/library/python:3.10

WORKDIR /app

COPY fastapi_service.src/fastapi_binary.pex /app

ENTRYPOINT ["/app/fastapi_binary.pex"]

I'm able to run the pex binary locally, but when I build application and try to run in container I have the following errors:

Failed to find compatible interpreter on path /usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin.

Examined the following interpreters:
1.) /usr/local/bin/python3.10 CPython==3.10.14
2.)       /usr/bin/python3.11 CPython==3.11.2

No interpreter compatible with the requested constraints was found:

  Failed to resolve requirements from PEX environment @ /root/.pex/unzipped_pexes/715888b8f41a11e76242694c94b6991d2f9ff25a.
  Needed cp310-cp310-manylinux_2_36_x86_64 compatible dependencies for:

      Required by:
        fastapi 0.109.2
      But this pex had no ProjectName(raw='pydantic', validated=False, normalized='pydantic') distributions.
   2: yarl<2.0,>=1.6
      Required by:
        gql 3.4.1
      But this pex had no ProjectName(raw='yarl', validated=False, normalized='yarl') distributions.
   3: pydantic[email]<3.0,>=1.7

        hera 5.15.1
      But this pex had no ProjectName(raw='pydantic', validated=False, normalized='pydantic') distributions.
   4: charset-normalizer<4,>=2
      Required by:
        requests 2.32.3
      But this pex had no ProjectName(raw='charset-normalizer', validated=False, normalized='charset-normalizer') distributions.
   5: pyyaml>=5.1
      Required by:
        pre-commit 3.5.0
      But this pex had no ProjectName(raw='pyyaml', validated=False, normalized='pyyaml') distributions.
   6: pydantic==1.10.13
      But this pex had no ProjectName(raw='pydantic', validated=False, normalized='pydantic') distributions.

I'm a bit stuck here and don't really understand what's the issue and why dependencies are not coming inside of pex... Would be happy to get some understanding ❤️
