how to contribute with docker image for arm platforms?

[lumpsoid]

Currently the repository only has a docker image for amd platforms, and it cannot be run on arm platforms such as raspberry pi. I checked that the dockerfile uses an image that supports arm, so there is no problem building such an image and I successfully built it for myself, but as I understand it would be more convenient if this image was already available.

Could you please tell me how I can send/upload this arm docker image as part of this repository?

Hello, thank you for your post!

What did you change to build and run a successful image for arm platforms? The images are built automatically, so the workflow would be more interesting for me than the final result 😄

I just have raspberry pi, and I just built image on it, but I found out that there is buildx plugin for docker cli, that allows to build docker images for multiple cpu architectures.
as far as I understand you need something like this docker buildx build -t docker.io/xx/myimage:v1 -f [path to Dockerfile] --push --platform=linux/arm64,linux/amd64 [path to build context]

find out how to setup github actions to build for multiple platforms
https://docs.docker.com/build/ci/github-actions/multi-platform/

in your docker-image.yml in last section with you need to add list of platforms to build
platforms: linux/amd64,linux/arm64

Ouch, I was no longer working on LWT when I received your answer, and I totally forgot this thread, sorry 🙏

Your answer was good one, with the great help of @ProgramComputer we rewrote the GitHub action to build multiple images (#169).

Enjoy!
