Currently, the multi-stage Docker build makes the `release` stage inherit from `dependencies`, which will include any files created by the `pip install` process in the final image. By using `pip install --user` to make dependencies be installed in `~/.local`, we can only copy those files into the final image, reducing the image size: ``` cloudflare-ddns-fix-applied latest 68427bd7c88d 3 minutes ago 54.6MB cloudflare-ddns-master latest 2675320b651d 8 minutes ago 65.9MB ``` A good resource going deeper on how this approach works can be found at https://pythonspeed.com/articles/multi-stage-docker-python/, solution 1.
