MultiArch Builds

docker: Error response from daemon: image with reference multiarch/qemu-user-static was found but does not match the specified platform: wanted linux/arm64, actual: linux/amd64.

This error message suggests that you are trying to run a Docker image on a platform that is different from the one for which the image was built. The image you are trying to run is built for the linux/arm64 platform, but the platform of your host system is linux/amd64.

To resolve this issue, you can use a tool called qemu-user-static to run the linux/arm64 binary on your linux/amd64 system. The qemu-user-static tool allows you to run binaries for foreign architectures on your host system by providing a lightweight emulation layer.

To use qemu-user-static, you need to follow these steps:

1. Install the qemu-user-static package on your host system. On Ubuntu or Debian, you can do this with the following command:

sudo apt-get install qemu-user-static

2. Download the multiarch/qemu-user-static Docker image for the linux/arm64 platform:

docker pull multiarch/qemu-user-static:register

3. Register the qemu-user-static binary as the default interpreter for the linux/arm64 platform:

docker run --rm --privileged multiarch/qemu-user-static:register --reset

4. Try running your Docker image again:

docker run my_image

This time, Docker should use the qemu-user-static binary to run the linux/arm64 binary in your Docker image on your linux/amd64 host system.


I am using macos

I apologize for the confusion. binfmt-support is a Linux package that provides support for registering binary formats with the kernel, and it's not available on macOS.

On macOS, you can use a tool called docker-binfmt to register support for foreign architectures. Here are the steps you can follow:

1. Install docker-binfmt by running the following command in a terminal:

brew install docker-binfmt

2. Enable docker-binfmt by running the following command:

bsudo docker run --rm --privileged docker/binfmt:a7996909642ee92942dcd6cff44b9b95f08dad64

This command will enable support for various foreign architectures, including linux/arm64.

3. Try running your Docker image again:

docker run my_image

This time, Docker should be able to run the linux/arm64 binary in your Docker image on your macOS host system.

I hope this helps!
