It is working dockerfile.

It is working dockerfile. In fact, pip of python2 was excluded from repository. This tricks help to overcome that.

Okay, I was looking into getting a usable version of qira working with newer binaries (with new libc version dependencies)

To get that working, I created use multi stage docker builds. The first stage is the same as yours @big-town , but then I copy it over to ubuntu 23 (or container of your choice) and then set up pyenv.

Sharing the dockerfile here in case it helps people like past me.

WORKDIR /tmp

And then mounting the container, allows me to work with a binary directly in the workdir of the container with : docker run -it -p 4000:4000 -p 3002:3002 -v ${PWD}:/tmp qira:latest
