I'm trying to build a docker image for which I expect to add dependencies to the context. It works as intended with a pex binary, but can't figure out how to do it with a python_distribution target. In my

docker_image

definition, I'm adding the python_distribution

src/python/dep1:dist

to the

dependencies

. But in my Dockerfile:

COPY src.python.dep1/dist.whl /wheels/dep1.whl

returns a

COPY failed: file not found in build context or excluded by .dockerignore: stat src.python.dep1/dist.whl: file does not exist

Not clear in here how the syntax should be, is

.ext

supposed to be

.whl

in this context ?

Judging by the docs it should be named in a similar fashion as if you ran

./pants package src/python/dep1:dist

, so try that and verify that what's in your

Dockerfile

is the same as what's in

dist

.

Please check the same discussion here https://pantsbuild.slack.com/archives/C046T6T9U/p1658928996776849

thanks for sharing this thread, that seems very useful indeed. In my case the version of the python distribution is inferred using setuptools-scm, any idea how could I determine the appropriate version in the Dockerfile ? (the

X.X.X

in

<http://src.python.my|src.python.my>_package/my-package-X.X.X.whl)

Are you using Pants's setuptools-scm support, or is it external to pants?

Are you using Pants's setuptools-scm support

I might have missed it actually, how does this work ? Currently I'm using a homemade plugin to achieve this, something of the form :

from setuptools_scm import get_version

@rule
async def setup_kwargs_plugin(request: CustomSetupKwargsRequest) -> SetupKwargs:
    """set package version using setuptools_scm
    """
    return SetupKwargs(
        {**request.explicit_kwargs, "version": get_version()}, address=request.target.address
    )
