docker-buildx-drone

Deprecated

Buildx now comes bundled with Docker Engine and this image is no longer needed.

https://docs.docker.com/buildx/working-with-buildx/

Motivation

My continuous integration and continuous delivery (CI/CD) platform of choice is Drone. What is particular about this platform is that every step of the pipeline is executed inside an isolated docker container.

Buildx is an experimental feature available on Docker 19.03+ which allows the user to build images for multiple architectures.

The purpose of this image is to provide the latest Docker as well as the latest Buildx binary pre-installed.

Description

This image is based on Docker latest image and includes the latest Buildx binary. The Buildx binary version can be changed at the Docker image build-time.

Currently, this Docker image only supports amd64.

Example

Here is an example of a pipeline for Drone CI.

---
kind : pipeline
type: docker
name: build and publish docker image

platform:
  os: linux
  arch: amd64

trigger:
  event: [ push, pull_request ]

steps:
  - name: publish
    image: gordonpn/docker-buildx-drone
    environment:
      DOCKER_TOKEN:
        from_secret: DOCKER_TOKEN
    volumes:
      - name: dockersock
        path: /var/run/docker.sock
    commands:
      - echo $DOCKER_TOKEN | docker login -u gordonpn --password-stdin
      - docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
      - docker buildx rm builder || true
      - docker buildx create --name builder --driver docker-container --use
      - docker buildx inspect --bootstrap
      - cd /drone/src/project-one
      - docker buildx build -t yourUsername/yourRepo:yourTag --platform linux/amd64,linux/arm64 --push .
      - cd /drone/src/project-two
      - docker build -t yourUsername/yourRepo:yourTag .
      - docker push yourUsername/yourRepo:yourTag

volumes:
  - name: dockersock
    host:
      path: /var/run/docker.sock

Building image with a different Buildx version

cd $PROJECT_DIR
docker build --build-arg BUILDX_VERSION=v0.4.0 .
