How to create a docker image with multiple platform?

1. Create a builder

docker buildx create --name armamd

2. Select the created builder

docker buildx use armamd

3. Build an image targeting linux/arm64 and linux/amd64

docker buildx build --platform linux/amd64,linux/arm64 -t ryojpn/go-cpu-intensive:latest .

Replace ryojpn with your DockerHub ID.

Optionally, you can add --push option to directly push the built image.
