[FEATURE] Image for ARM

[JesusMtnez]

Is your feature request related to a problem? Please describe.

I currently using a k3s cluster on top of five Raspberry Pi 3. I would like to be able to use Kimai in it.

Describe the solution you'd like

Add a build process to the Docker using alpine for ARM.

[Schrolli91]

Unfortunately I have no experience with cross-build's for docker.

I have tried to build a multi-arch image but also have zero experience. I think I have pushed a manifest for the muti arch images. @JesusMtnez can you test this please?

[JesusMtnez]

Thank you @tobybatch ! I'll try to check it later this week

[tobybatch]

@JesusMtnez bump, do the arm images work?

[MRIIOT]

Have not tried, but I see arm64 as architecture. Raspbian Buster OS is still 32bit.

This runs fine so far on RPi4.

Thanks for that. I'll close this issue now
