How do I build a docker image specifying a specific arch on Apple Silicone

Make sure “Use Rosetta for x86/amd64 emulation on Apple Silicon” is turned on in Features in development, and virtualisation is turned on in general settings

Use buildx

docker buildx build --platform linux/amd64 -t your-image-name .

Use platform to avoid warning when running

docker run -d --platform linux/amd64 --name test-container kev-arch-builder-image bash -c "tail -f /dev/null"

#docker
