How to build ARMv6 and ARMv7 in the same manifest file. (Compatible tag for ARMv7, ARMv6, ARM64 and AMD64)

Enabling experimental feature of Docker Desktop on macOS (Mojave, Docker 2.1.0.4 Stable), we get the following platforms from buildx command.

$ docker buildx ls
NAME/NODE DRIVER/ENDPOINT STATUS  PLATFORMS
default * docker                  
  default default         running linux/amd64, linux/arm64, linux/ppc64le, linux/s390x, linux/386, linux/arm/v7, linux/arm/v6

This means that we can build images for these platforms on macOS.

• PLATFORMS: linux/amd64 linux/arm64 linux/ppc64le linux/s390x linux/386 linux/arm/v7 linux/arm/v6

Currently we're building images on each platform and push them to Docker Hub one by one. But if we can make a script that build and push them, it might help us a lot, doesn't it?

The following articles might help us to do so:

• Build with buildx | Working with Docker Buildx (experimental) @ docs.docker.com
• Raspberry PiでDockerを動かす @ Qiita
• How I built ARM based Docker Images for Raspberry Pi using buildx CLI Plugin on Docker Desktop? @ Collabnix

Wrong Tag for macOS architecture. Must be AMD64 or x86_64 instead of ARM64

Dockerfile_of_Alpine/build-image.sh

Lines 12 to 15 in d2052b2

	- On Mac:
	This script will update this repository, builds Docker image for AMD64 and
	pushes to Docker Hub. The image tag will be:
	keinos/alpine:arm64

Provide one docker image tag for both ARM and x86_64 architecture.

TL;DR

It would be nice if the image can be pulled by keinos/alpine:latest for both ARM and x86_64 architecture.

TS;DR

Currently, this image (keinos/alpine:latest) provides only for x86_64 architecture. Because of the current specification of the automated build on DockerHub.

Since most of my images on Docker Hub are based on keinos/alpine image, I want them to be compatible with ARM and x86_64.

The keinos/php8-jit image provides both (with different tags).

But to build ARM image, I had to rebuild the keinos/alpine first, then keinos/php8-jit on my RaspberryPi and then push it to Docker Hub.

If we can provide both ARM and x86_64 in one keinos/alpine:latest tag, it will ease me to rebuild the other images for ARM.

How

• Prepare Manifest file for both architectures

  • REF: Docker Multi-Architecture Images @ Medium

• Receive webhook from Docker Cloud to RPi when the automated build succeeds. Then RPi builds and pushes the ARM image.

  • The endpoint of RPi to receive the webhook, using ngrok or serveo might be nice and simple.
