Docker support for ARM processors?

[ParmuSingh]

I have had problems running docker instance on my raspberry pi 4. As it turns out the image is not for ARM architecture, which a rpi uses.

After going through some pain I was able to install from source and compile a binary for my rpi

So the good news is that taskcafe does work on ARM.

The feature request is to have a docker image available for ARM architecture, as it'll help in easy deployment on rpi.

If I am able to do it on my machine without actually having an ARM chip, then sure I can provide ARM images.

Anyway I can help with that? I compiled on a raspberry pi. If I share my binary would that help? I just don't know how to dockerize it.

My best guess would be using an arm64 image of Ubuntu or some lightweight OS and run the same compile process for any Docker image (which I'm assuming is compiling the binary, and then building the image)
Of course, you'll have to make sure the arm version of the image uses everything ARM such as the OS and the GoLang tools for compiling (I'm assuming).

I looked into it and from what I've found the best for me to release arm64 images (since I don't have an ARM based computer) is to use the buildx tool. Unfortunately it seems kind of annoying to install, but I'll try building the 0.4.0 release with it.

@JordanKnott How to you create your docker-image? Manually? I couldn't find a .github/workflow-file ...
I think the best would be to build with docker buildx, there is a github action for this, so no local install neccessary: https://github.com/docker/setup-buildx-action
I've done something similar before, but didn't need to push it to dockerhub.

[Cyber1000]

Something simple as this (without the multi-registry if not wanted), might suffice: https://github.com/docker/build-push-action/blob/master/docs/advanced/push-multi-registries.md

And the on-part could be something like this (executed on every creation of a new release, instead of every push to main):

on:
  release:
    types:
      - created

+1 for arm64 please

I also want to run it on a raspberry pi which is running a linux armv7 can you pls provide an image compiled under this environment, thanks.
