ARM builds

[klafbang]

I see the old Docker Hub registries contained an arm64 build as well as an intel build, but the new registry doesn't seem to (I seem to only get a single image without any tagged architecture, and it definitely doesn't run on an ARM host).

I think it would be nice to also provide arm builds; it is becoming increasingly popular on both laptops and servers.

It seems it should be relatively easy to build arm images on Github, https://github.blog/news-insights/product-news/arm64-on-github-actions-powering-faster-more-efficient-build-systems/, but of course it also requires arm native docspell releases since the image currently downloads those.

@eikek Does docspell itself carry any platform dependent code? Or does it ship multiple architectures anyway?

[klafbang]

It seems there's no (obvious) platform-dependent code in the distributed .zip.

I tried blindly building ARM images manually using the script in this repo, and from the testing I've done so far, it seems to work.

My images are presently in https://gitlab.westergaard.eu/klafbang/docspell/container_registry

I have a DocSpell instance running using these images on an ARM server at https://docspell.westergaard.cloud/ – I just changed the images and the nodeSelector and things seem to just work.

[pschichtel]

are you willing to contribute the necessary changes here?

[klafbang]

No changes were necessary to make the build manually, just running the script on an ARM machine. In principle, it's also possible to "cross-compile" using dockerx, but that's terribly slow.

I can see about making the change to the Github CI files to run on an ARM machine, but I'm not terribly familiar with GitHub's CI system.

it might be somewhat simple to do this using a matrix build, running the current job once per arch, producing the full image as a job output and then having a new job that collects the outputs and builds the multi-arch manifest
