Add ARM and ARM64 builds on docker hub

[SenorSmartyPants]

Please add ARM and ARM64 builds on docker hub in addition to AMD64. Thanks

[PiDockMedia]

comixed/comixed:latest should be multi-arch now. I only tested the amd64 image but it seemed to build with no errors. Give it a try and let me know how it goes for you.

[SenorSmartyPants]

This seemed to be working earlier, but when I pulled latest there is only amd64 build now.

Hi, I tried to install a container in a Raspberry pi 4 using your image on dockerhub but got the error:
exec user process caused "exec format error"
I think that means there are'nt still ARM builds. Do you plan to release them? Thanks!

@crivote Hi, thanks for bringing that to our attention. Do you know what exec is causing that error? We have a dependency on webp-imageio for handling WebP pages in a comic, which is the only part of the project that contains native code. In the JAR I see:

So is it one of those that's causing the error for you? If so, I'd recommend visiting their Github page and file a bug with them, and referring back to this ticket as well.

Hi,

still got the same problem installing Comixed on a Raspberry Pi4 with Ubuntu server:

standard_init_linux.go:211: exec user process caused "exec format error"

[mcpierce]

@FrancisKunz Ah, and I see that webp-imageio has had a few releases since this issue was reported (we're using 0.1.2 and right now they have 0.1.6 available).

I'm cutting a new release (0.8.0-2.0) now and, if you find that it fixes this issue, please let me know and we can mark this as fixed.

[FrancisKunz]

@mcpierce as soon as the new docker image is up, i'll update you on the status

[FrancisKunz]

bad news ...
Comixed 0.8.0-2.0
standard_init_linux.go:211: exec user process caused "exec format error"

[mcpierce]

@FrancisKunz Bugger.... Sorry to say, but it's a bug outside of our codebase. That's an error in the webp-imageio library that we're using, and we can't fix bugs like that.

Would you mind opening a bug with them and referencing this bug?

[mcpierce]

Re-opening this so we make the Docker image itself multi-arch.

Thanks for re-opening this. I have no real experience with building docker images but judging from this guide https://www.docker.com/blog/multi-arch-build-and-images-the-simple-way/ it should be quite straightforward for you to create a multi-arch image with buildx.

Literally the link I was just reading to see what I can do to meet this request. 😄

[mcpierce]

I wonder, since we use their Github action to publish our updates to Docker, if we can't use this feature to publish for ARM as well?
