Deploy an editable CLI application python package in Docker

Question

I am trying to deploy an editable CLI python package in the docker.

My package is successfully built in the docker and when I execute docker run greet-docker greet --help it shows the help message with the subcommand.

When I execute the docker run greet-docker greet say sam it should echo Hi sam but it shows the help message with the subcommand.

What did I miss!!

This took me almost a day to figure out. Remove the ENTRYPOINT [ "greet", "--help" ] from the docker file. Whatever command we run in the editable gets overwritten by the ENTRYPOINT.
