Summary

See discussion in #104.

We currently assume the presence of a Python interpreter + the ability to create a new user with UID 1000. This does not hold for many common base images, for example those based on Ubuntu, Alpine Linux, Conda images, CUDA images, ...

We should get this tested on CI and solve issues systematically.

Why is this needed?

Right now, the base image feature is barely usable, and users are pretty much forced to go with Debian, which is sometimes not an option.

Usage example

Use build config with base_image: ubuntu:latest and execute tesseract build without errors.
