Build Docker images for platform arm64 (Apple M1) and amd64 on Apple M1 with Docker Desktop.

Docker on multiple platforms (made by the author)

Prerequisites

Docker environment has been set up, Docker Engine: 20.10.1 recommended,
and version 4.3.0 (71786) for Docker Desktop is recommended as it almost natively supports Apple M1.

Install Docker Buildx plugin

# Download buildx plugin
curl -LO https://github.com/docker/buildx/releases/download/v0.7.1/buildx-v0.7.1.darwin-$(uname -m)
# Move buildx to cli-plugins and make it executable
mkdir -p ~/.docker/cli-plugins
mv buildx-v0.7.1.darwin-$(uname -m) ~/.docker/cli-plugins/docker-buildx
chmod a+x ~/.docker/cli-plugins/docker-buildx

Prepare the environment for building the images

Here the settings are for building amd64 and arm64

docker buildx create --driver-opt image=moby/buildkit:master  --name builder --driver docker-container --use
docker buildx inspect --bootstrap
docker buildx create --platform linux/amd64
docker buildx create --platform linux/arm64,linux/arm/v8

Build and push to Docker hub

Steps:

1. Login Docker Hub: docker login
2. Build and push to Docker hub:
   docker buildx build — push -t TAG — platform linux/amd64,linux/arm64 -f Dockerfile .

About the tag

A tag for the image you need to replace TAG. Note: The dot at the end of the command is a part of the command. The format of the tag looks like docker_hub_id/image_name:version. For example: wxwmatt/rails:6.1.4.1-alpine3.15.

Put all commands together

curl -LO https://github.com/docker/buildx/releases/download/v0.7.1/buildx-v0.7.1.darwin-$(uname -m)
mkdir -p ~/.docker/cli-plugins
mv buildx-v0.7.1.darwin-$(uname -m) ~/.docker/cli-plugins/docker-buildx
chmod a+x ~/.docker/cli-plugins/docker-buildx
docker buildx create --driver-opt image=moby/buildkit:master  --name builder --driver docker-container --use
docker buildx inspect --bootstrap
docker buildx create --platform linux/amd64
docker buildx create --platform linux/arm64,linux/arm/v8
docker login
docker buildx build --push -t docker_id/image:version --platform linux/amd64,linux/arm64 .
