re: Docker-first Python development VIEW POST


This is pretty awesome. I wonder if you could copy from the builder stage to the tests_builder stage by modifying tests_builder to copy from the builder stage like so:

FROM test_deps as tests_builder

COPY --from=builder ./src ./src

COPY tests ./tests

Disclaimer: I'm not 100% sure this would fit your use case, but it's worth a shot. If you try this out, let us know how it worked for you.


You can definitely do this, but Docker still has to create a new layer for it. Copying it from the builder stage could definitely help if building the src dir is more complicated than copying over a single directory.


That's true, I didn't think of the extra layer Docker would add in the process.
