ARM64 Devcontainer

[londospark]

For people who use M1/M2 macs and other ARM64-based devices could we please get an ARM64-native docker image for https://hub.docker.com/r/purtontech/rust-on-nails-devcontainer/?

@londospark That's a great idea. If you know how to do it let me know, otherwise I'll do some research.

Thank you - I don't know how to do it off hand but I suspect that someone would need to have access to the original Dockerfile to update the image and add an arm64 version

We should be able to do this using docker buildx for multi-platform builds.

Example:

$ cd /path/to/rust-on-nails
$ docker buildx build --platform linux/arm64 nails-devcontainer
 ...
 => => writing image sha256:5c9c95cb837f7e6d2c447dbe5a614e8726ba6ee336f49416f840c3431bba27b9
$ docker image inspect --format "{{.Architecture}}" 5c9c95cb837f7e6d2c447dbe5a614e8726ba6ee336f49416f840c3431bba27b9
arm64

See https://docs.docker.com/build/building/multi-platform/ for more information.

I also opened #27 to resolve one issue I ran into when building an arm64 target.

I created a personal image in the meantime: https://hub.docker.com/layers/hjr3/rust-on-nails-devcontainer/db5471a/images/sha256-ed9f94c06d7dffe0865e5d7f44cfe1d0ef870ec0c6fa17498b27406650957de0?context=repo

I tried

docker buildx build --platform linux/arm64 dev-env-as-code

And it locked up while trying to build the cornucopia and cargo-chef. I'll ask these guys if they will build binaries as it makes sense that they get built upstream.

Then we'll need to be aware of packages that get downloaded should use these var to get the correct version.

TARGETOS : Target platform operating system. e.g. linux
TARGETARCH: Target platform CPU architecture. e.g. arm64
TARGETVARIANT : Target platform CPU architecture Variant. e.g. v8

purtontech/rust-on-nails-devcontainer/ seems to have started including arm64 builds last month, perhaps this issue can be closed?
