Docker 特拉维斯多体系结构建筑

我有一个项目，我正在尝试为arm和x86_64构建

x86_64构建通过，但arm构建失败，原因是：

Status: Downloaded newer image for kutsudock/rpi-alpine-go:latest
standard_init_linux.go:175: exec user process caused "exec format error"

这是我的yaml：

env:
  global:
    - VERSION=1.${TRAVIS_BUILD_NUMBER}
  matrix:
    - ARCH=x86_64
      GOIMG=golang:1.6
      DOCKER_BUILD=mastermindg/docker-flow-proxy:${VERSION}
      DOCKERFILE=Dockerfile.amd64
    - ARCH=rpi
      GOIMG=kutsudock/rpi-alpine-go
      DOCKER_BUILD=mastermindg/docker-flow-proxy:rpi-${VERSION}
      DOCKERFILE=Dockerfile.rpi

sudo: required

services:
  - docker

script:
  - docker run --rm -v $PWD:/usr/src/myapp -w /usr/src/myapp -v go:/go ${GOIMG} bash -c "cd /usr/src/myapp && go get -d -v -t && go test --cover -v ./... --run UnitTest && go build -v -o docker-flow-proxy"

after_success:
  - docker build -t ${DOCKER_BUILD} -f ${DOCKERFILE} .
  - '[ "${TRAVIS_PULL_REQUEST}" = "false" ] && docker login -e $DOCKER_EMAIL -u $DOCKER_USERNAME -p $DOCKER_PASSWORD || false'
  - '[ "${TRAVIS_PULL_REQUEST}" = "false" ] && docker push ${DOCKER_BUILD} || false'

branches:
  only:
    - master

如何在Travis上构建arm Docker图像？

查看Travis后，我发现了以下问题：

多亏了@moul Debian，Debian有了一个多拱引导。只需在Docker运行之前注册qemu即可

就你而言：

docker run --rm --privileged multiarch/qemu-user-static:register
docker run --rm -v $PWD:/usr/src/myapp -w /usr/src/myapp -v go:/go ${GOIMG} bash -c "cd /usr/src/myapp && go get -d -v -t && go test --cover -v ./... --run UnitTest && go build -v -o docker-flow-proxy"

使用ARM 64位（aarch64）和ARM 32位（armv7l）的方法如下：

docker run --rm --privileged multiarch/qemu-user-static:register --reset

docker run --rm -t multiarch/ubuntu-debootstrap:arm64-bionic uname -a
Linux 28c784e9c7bc 4.4.0-101-generic #124~14.04.1-Ubuntu SMP Fri Nov 10 19:05:36 UTC 2017 aarch64 aarch64 aarch64 GNU/Linux

docker run --rm -t multiarch/ubuntu-debootstrap:armhf-bionic uname -a
Linux 4de7b4e919b0 4.4.0-101-generic #124~14.04.1-Ubuntu SMP Fri Nov 10 19:05:36 UTC 2017 armv7l armv7l armv7l GNU/Linux

上周TravisCI宣布了多体系结构支持，包括现在的Arm支持，对所有开源项目都是免费的。请参阅本博客文章：
