How to build a multi-architecture Docker Image on Apple Silicon This allows you to build a Docker Image for a variety of different CPU architectures and it uses QEMU under the hood to do the emulation. It’s a CLI plugin that integrates the Moby BuildKit toolkit. This means this image can’t run on any other device like a raspberry pi (linux/arm/v7) or a typical server (linux/amd64) as the application binaries inside are not compatible.įortunately, Docker has supported cross CPU architecture builds for a while now through an experimental feature called buildx. When I build a Docker image on my Mac – it builds an ARM version (specifically arm64). I extensively use Docker in the projects I work on, so this led to a unique problem. My Apple Silicon MacBook Air is now my daily driver that I use for work as a software engineer and for personal projects. I jumped on the Apple Silicon band wagon as soon as I heard how awesome they were and I was not disappointed.
