Docker MultiarchBuilder - Docker image

DISCLAIMER: As-of 2021, this product does not have a free support team anymore. If you want this product to be maintained, please support on Patreon.

The purpose of this project is to build a Multiarch Docker image in a x86/64 CI/CD context.

Sample

Here is an example if .gitlab-ci.yml file to compile

image: femtopixel/multiarchbuilder
variables:
    DOCKER_HOST: "tcp://docker:2375"
services:
    - docker:dind

stages:
    - build

build:
    stage: build
    only:
        - master
    before_script:
        - echo "$DOCKER_HUB_PASSWORD" | docker login -u "$DOCKER_HUB_LOGIN" --password-stdin
        - docker buildx create --driver=docker-container --name=buildkit-builder --use
    script:
        - make build

With this, your build task in your Makefile will be able to build an image for other architectures without needing to add qemu into your dockerfiles. Here is the magic :

• binfmt-support is installed in femtopixel/multiarchbuild
• qemu is installed in femtopixel/multiarchbuild
• docker is installed in femtopixel/multiarchbuild
• qemu-user-static is registered as available binfmt interpreter
• manifest-tool is installed so you'll be able to create hub manifest to deploy multiple image arch to your docker repository
• qemu-static-conf are added/registered to binfmt so qemu will be used to interpret in your build context
