I see a proposed work-around here but I haven't yet managed to rejigger the FROM clause in the Dockerfile to make the fix work yet so I thought I'd also mention it here :)

[feoh]

I got it to work with this Dockerfile. I can generate a pull request if anyone likes. I won't do it un-asked since it's a bit of a departure from what's already there.

@feoh Thanks for reporting the issue and providing a potential fix! My knowledge of Docker is limited hence I am unsure how to proceed with your suggested fix. Ideally, those that have contributed Docker support to Contextualise weigh in :) @machawk1 @epilys @stratosgear @Nekroze

[machawk1]

@ibnesayeed has some Docker expertise, so it would be helpful for him to have a quick look at the Dockerfile for wellformedness and adherence to contemporary good practice.

I don't see any issues in changing the base image to alpine as it may reduce the image size as well, but test building the image and the runtime properly before going for that change.

Alternatively, use build args to customize the base image and leave the default value as it is for now. Those who want to change the base image to alpine can create a custom image that has the additional apk update... layer in it then use that image as the base by providing a build arg.

try doing pip install setuptools then the rest of your commands. There's likely to be a wheel available for setuptools, and you should be able to install without a problem.

Honestly it's weird that pip is available, but the de-facto packaging module setuptools is not available.

[feoh]

I don't understand enough about the alternative solutions people are suggesting to implement them, and I have something that works and left a crumb trail for anyone who just needs a quick fix to get this running on a pi, so I'll yield to your greater expertise and close this :)

@feoh Thank you. I really do appreciate your contribution to Contextualise.
