You can see the compatible platforms from the previous docker buildx ls command.
ENABLE MULTI STAGE BUILDS FOR DOCKER ON MAC SOFTWARE
Don’t forget to tag it (the example is using the open source MemberMatters software I wrote) and add a list of all the platforms that you wish to build for. You’ll have to push it straight to a registry (either the public or a private one) with -push if you want Docker to automatically manage the multi-architecture manifest for you. Now you can use buildx like below to start a multi-architecture build. Reverent_banach0 unix:///var/run/docker.sock running linux/arm64, linux/amd64, linux/riscv64, linux/ppc64le, linux/s390x, linux/arm/v7, linux/arm/v6 $ docker buildx lsNAME/NODE DRIVER/ENDPOINT STATUS PLATFORMS You’ll see it created if you run docker buildx ls again. Without this step, you’ll have to use the default Docker one which only supports a single platform per build. Next create a new builder instance with docker buildx create -use so we can perform multiple builds in parallel. NAME/NODE DRIVER/ENDPOINT STATUS PLATFORMSĭefault default running linux/arm64, linux/amd64, linux/riscv64, linux/ppc64le, linux/s390x, linux/arm/v7, linux/arm/v6 You should see something similar to below.
Run the docker buildx ls command to list the current builder instances. In your terminal, open the folder that contains the Dockerfile you wish to build for multiple architectures. Once you’ve enabled experimental features, you can close the Docker Desktop preferences. I suspect it’s a new thing which is why only recently created accounts seem to need to sign up. If you can’t see an “Experimental Features” option, you may have to sign up for the Docker developer program at this link. To do so, open up Docker Desktop then navigate to Preferences. The Docker buildx feature is currently “experimental” so we need to enable Docker Desktop’s experimental feature support. Step 1: enable experimental Docker Desktop features It was written with an Apple M1 equipped MacBook Air so results may vary across devices. This guide assumes you have an Apple Silicon equipped Mac running macOS Big Sur.

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. Want a set of commands you can copy/paste? Jump to the TLDR at the bottom.
