You can avoid this by building cryptography as a docker stage and then just extract the wheel as part of your docker build process. Alternately if you install rust, build cryptography, and uninstall rust all in one layer then you can also avoid this issue.

That's what I currently do already but I did notice that I failed to uninstall gcc when looking at the Dockerfile again today so I'm now down to 150MB (after rebuilding). Still not great but better.

Currently my build uses Ubuntu, I'm going to try switching over to Alpine when I get a chance to see how much savings I can claw back.
