将私有 PyPi 存储库导入 Docker 容器

Question

I'm trying to Dockerize a Python application that uses a package from a private PyPi repository. The problem is, none of the guides I'm finding online seem to work. I'd imagine such a thing is probably used fairly widely so it can't be that difficult to do, but I seem to be having trouble.

I am able to run this application through a regular development environment (ie command line) so the repository is working fine and connecting to it works normally. I just can't get Docker to recognize it. I found this guide on Medium which claims to do what I want; according to my sysadmin I shouldn't need SSH so I ignored that part but I imported my pip.conf file using the steps in that guide. I was able to confirm that the pip.conf was being imported using the required flag as suggested in that article, except that it's failing when I try to pip install. Here's my docker command and dockerfile, please help.

HOME?=`echo $HOME`

my-make-command:
    DOCKER_BUILDKIT=1 && \
    docker build --secret id=pip.conf,src=${HOME}/.pip/pip.conf -t tag .

# syntax=docker/dockerfile:1.0.0-experimental

FROM python:3.8-alpine

COPY * .

RUN --mount=type=secret,id=pip.conf,required pip install -r requirements.txt
CMD ["python3", "app.py"]

My guess would be that you need to be using the company's internet / VPN to access your private PyPi repository.

If so, maybe you could try adding the --network host param to your docker build command.

You may need to restart Docker after connecting to the VPN.
