Cannot build docker image (no rust compiler) #6

Closed hno2 closed 3 years ago

hno2 commented 3 years ago

The Module cryptography cannot be build as it requires a (non-existing) Rust compiler. (error: can't find Rust compiler)

hno2 commented 3 years ago

So I think I found a fix and changed my Dockerfile to 

FROM python:3-buster

ADD requirements.txt /tmp
RUN pip install --upgrade pip
RUN pip install -r /tmp/requirements.txt

EXPOSE 9001
CMD python app.py

I believe this is due alpine having no native build wheel for cryptography

hi @hno2 . Thanks for pointing me to this issue! I appreciate it. I've just made some changes so now docker-compose must work fine: https://github.com/dmitry-viskov/pylti1.3-flask-example/commit/907b0377e305feee02acd20893e6c9e9bfd4e538

I've just pinned version of the cryptography library. This version is a little bit outdated and has some security vulnerabilities but it is the easiest solution. Unfortunately the last versions of cryptography requires significant time to compile library code so that looks too redundant for such test project.
