Komga: Docker image for ARM/Raspberry Pi

[null-von-sushi]

Sorry if this is not the place to ask, just close this issue.
I was hoping to try out komga and install it in a recently aquired raspberry pi. I have not actually used docker before, but I thought I would give it a try.

The issue is I am getting errors.
2020-01-04T12:26:48.727237849Z standard_init_linux.go:211: exec user process caused "exec format error

I am going to take a guess and assume this is due to komga only being made for x86 platforms? From the readme I got the impression that komga is writtein in Java, so shouldn't this work on ARM as well?

Hello,

Java works on ARM and Raspberry Pi. You need to use OpenJDK 11 though, else the performances are awful (see #23).

For docker it's another story, the docker image needs to be built for ARM. Docker now has some tools in beta to build multi-arch versions from a single machine, but i have found no easy way (yet) to integrate that in my CI setup.

You can run it from the jar in the meantime.

Oh okay, I didn't know docker was architecture specific. Thank you for clearing this up, I will try running it myself with OpenJDK 11!

I have created a Docker image that should work as a direct stand-in for the official image:
https://hub.docker.com/repository/docker/basdp/komga_pi

This is just a workaround, until the official komga repo has arm images. But it works flawless for me on a Pi 4.

In the long term, we should upload arm builds along the amd64.

Thanks ! Would you be able to share details on how you build it ?

Even if i cannot get multi-arch to work with manifest lists, i could have an official image with a -arm suffix on all tags maybe.

Multi-arch images are now available ! 🚀
