ARM Dockerfile about ninjam-helm

[zeppelinux]

Hi there!

my rpi 400 melted in a house fire last this Tuesday (everybody are save), so I don’t have access to rpi build runtime anymore. You can check out/clone the repo https://github.com/zeppelinux/ninjam and try to build it on yours. Verify ninjas works.
Hopefully there is rpi target platform available in the GitHub and both builds (Linux and rpi) can be triggered automatically on the tag push. Let me know how it goes. Good luck!

[zeppelinux]

Looks good to me. Want to try and create PR?

oh man, that's terrible. i'm sorry to hear, but relieved to hear everyone is okay.

i'll keep investigating and see what i need to do to get'r done.

take care / best of luck

edit: managed to compile it locally and it runs fine.

i'm not super familiar with github actions, but it looks as if this is all that would be needed to build it for raspberry pi.

Sure thing; zeppelinux/ninjam#5.

Wasn't too sure what to do with the Docker push step...not sure if that's necessary.

[zeppelinux]

The docker image is built by the DockerHub itself (not GitHub). DockerHub gets notified by GitHub (web hoock) on successful release, so yes there is no need to push anything from GitHub. I saw images on DockerHub for multiple architectures in the same registry, so it looks like it is supported (but I'm not sure).
I will look at the Docker Hub build and see if it can build another image.

[ianhundere]

looks like you can either do it via your pipelines with buildx or use the ARCH env var in your Dockerfile to specify what architecture to use.
