Release images for Apple M1 / ARM

[spuder]

If you attempt to run these docker containers on an Apple M1 Processor, you get the following error

docker run openscad/openscad:2021.01 openscad version
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
standard_init_linux.go:228: exec user process caused: exec format error

Solutions

1. Use buildx as shown in this blog

Pros: Just works Cons: Requires docker desktop which is now a paid product if running on a work computer

2. Offload building ci images from developer workstation to github actions. Here is an example

Looks like docker buildx is still supported on CE. Latest release and dev snapshot are now available for both arm64 and amd64 platforms. Tested on Raspberry PI 400.

Older releases may or may not follow, if it just works, they'll appear in the near future.

If this works specifically for Apple M1, I can't test, so I'm going to close this as solved. There's not going to be dedicated M1 support for docker images at this point.

FWIW, all images are now available for both architectures: https://hub.docker.com/r/openscad/openscad/tags

Thank you. Tested and is working on M1 Mac

Thanks, that's very good news.

For future reference here was the solution. ( I find myself referring back to this issue frequently)
