Bump docker images to use python 3.8+

[creatorrr]

The haystack docker images currently come with python3.7. Unfortunately, library support for <=3.7 is starting to wane. Is it possible to bump the python version for the images to 3.8 or greater? Maybe publish separate versions?

Hi @creatorrr

with 1.9 we deprecated the old docker images (see release notes) and the new ones already ship Python 3.10 in their CPU flavour.

The GPU version uses a Pytorch base image that unfortunately is still on Python 3.7.

We didn't have the time to see if we can safely update the Pytorch version we depend on, or which version of Python the more recent Pytorch images ship, but if you don't need GPU support you might be already good to go with the new 1.9 image.

Gotcha, thanks for the update @masci . Unfortunately, I do need the gpu variants. Can you please point me to any specific docker build instructions that I can use? I'll try to see if I can get it built on base images with a more recent python version.

Have a look at https://github.com/deepset-ai/haystack/tree/main/docker it contains the bakefile to build the new images, you can take inspiration from there and try locally

@masci opened a pr (wip) that uses nvidia/cuda as base and installs python3.10 manually on top of it
