In this [docs](https://cloud.google.com/artifact-registry/docs/python/authentication) is clear how to authorize yourself to access a pypi gar.

But how do you do it inside a docker?
IS not clear based on the docs

example

```
FROM python:3.9-slim
RUN pip install --no-input keyrings.google-artifactregistry-auth
COPY container/pip_conf.conf /etc/pip.conf
RUN pip install private-library
```

how you make this docker inherit the gcloud access your terminal/computer has?

note
1)
ideally, i don't want to copy paste (or secrets, it's the same) the sa.
I want inheritance.

2)
compute engine magically works.
With same config, doing docker build inside the compute engine vm, has inheritance for the gar access.
