Hey! The image gcr.io/distroless/python3
has apparently the entry point set to the /usr/bin/python3.9.

The commands that this rule executes are stored into the script and passed as a commend to the image, but since the entrypoint is set to python, python reads it

I assume the rule should override entry point, since it executes a shell script.

As a work-around you can reset entry point by adding

    docker_run_flags = [
        "--entrypoint=''",
    ],

to you install_postgres rule.

The image you are using doesn't have apt as well, so you may want to use the other base image as well.
