swr-multiplatform-build-action

允许用户构建跨平台镜像,如linux平台,windows平台或macos平台,并可以直接推送到SWR等Docker镜像仓库上
目前支持的平台列表如下 

  'linux/amd64',
  'linux/arm64',
  'linux/ppc64le',
  'linux/s390x',
  'linux/386',
  'linux/arm/v5',
  'linux/arm/v7',
  'linux/arm/v6',
  'linux/arm64/v8',
  'linux/mips64le',
  'windows/amd64',
  'windows/arm64',
  'darwin/amd64',
  'darwin/arm64'

前置工作

(1) 如果项目代码需要打包,需要提前完成打包动作,并修改Dockerfile
(2) 如果需要推送到SWR等Docker registry上,需要添加一个docker login的action,添加好登录账号密码等信息
(3) 需要确定基础镜像支持的平台,可以登录dockerhub官网查看
如19-jdk,支持windows/amd64,linux/amd64,linux/arm64/v8 这三个平台,

参数说明:

Name Require Default Description
image_tag true 需要打包的docker镜像标签,如：swr.cn-north-4.myhuaweicloud.com/hcloudcli/jdkdemo:jdk19-v1.0.0.4
platforms false 当前需要打包支持的平台,用逗号隔开。如 linux/amd64,linux/arm64/v8,windows/amd64。如果不填写的话,会默认打包当前环境所在的平台,如ubuntu-latest所在的linux/amd64
file false Dockerfile路径,默认为Dockerfile,如果在其他目录,则填写相对路径或者绝对路径,如 ./dockerfiles/Dockerfile
use_latest_buildx false false 是否需要使用最新版本的docker buildx来构建docker镜像,如果为true,会比较当前安装的buildx和官方发布的最新版本,有差异的话会安装最新版本
push true false 是否需要将构建好的镜像推送到docker镜像仓库,如果填true,需要再前面增加一个docker login的 action完成镜像仓库的登录,在构建完成之后会自动推送到华为云SWR

使用样例

1、简单样例,只构建代码和打包镜像

步骤说明如下
(1) 完成jdk安装和java项目打包
(2) 填写image_tag参数,镜像会工具当前环境所在的平台,打包出一个 linux/amd64的镜像

    # 安装JDK和maven
    - name: Set up JDK 8 for Maven build
      uses: actions/setup-java@v1
      with:
        java-version: 8

    # 完成java项目打包
    - name: Build Maven project
      run: mvn clean -U package -Dmaven.test.skip
      
    # 完成docker镜像打包
    - name: Build Spring Cloud demo for linux/amd64
      uses: huaweicloud/swr-multiplatform-build-action@v1.2.0
      with:
        image_tag: swr.cn-north-4.myhuaweicloud.com/hcloudcli/jdkdemo:jdk19-v1.0.0.4

详情可参考 ./github/workflows/build-simple-demo.yml

2、普通样例,完成镜像的windows和linux平台构建,并上传到swr

步骤说明如下
(1) 完成jdk安装和java项目打包
(2) 设置docker login,填写AK和SK,完成华为云SWR容器镜像服务的登录
(3) 设置docker buildx,可以选配,插件会检查当前环境是否安装了docker buildx,如果没有的话,会自动安装
(4) 登录doocker hub,查看openjdk镜像,可以看到openjdk:19-jdk 支持 linux/amd64,linux/arm64/v8,windows/amd64三个平台,因此platforms参数可以填写这三个中的一个或多个,也可以填写全部。push参数填写为true,即打包完之后就push到华为云SWR avatar

    # 安装JDK和maven
    - name: Set up JDK 8 for Maven build
      uses: actions/setup-java@v1
      with:
        java-version: 8

    # 完成java项目打包
    - name: Build Maven project
      run: mvn clean -U package -Dmaven.test.skip 

    # docker login,设置登陆到华为的swr
    - name: Log in to Huawei Cloud SWR
      uses: huaweicloud/swr-login@v2.1.0
      with:
        region: cn-north-4
        access-key-id: ${{ secrets.ACCESSKEY }}
        access-key-secret: ${{ secrets.SECRETACCESSKEY }}
    # 设置 docker 环境
    - name: Set up Docker Buildx
      id: buildx
      uses: docker/setup-buildx-action@v1
      
    # 完成docker镜像打包,支持linux/amd64,linux/arm64/v8,windows/amd64三个平台
    - name: Build Spring Cloud demo for linux/amd64,linux/arm64/v8,windows/amd64
      uses: huaweicloud/swr-multiplatform-build-action@v1.2.0
      with:
        image_tag: swr.cn-north-4.myhuaweicloud.com/hcloudcli/jdkdemo:jdk19-v1.0.0.4
        platforms: linux/amd64,linux/arm64/v8,windows/amd64
        use_latest_buildx: false
        push: true
        file: ./Dockerfile

详情可参考 .github/workflows/build-springclouddemo-for-multiplatform.yml

3、复杂样例,完成镜像的复杂多平台构建,并上传到swr

步骤说明如下
(1) 设置docker login,填写AK和SK,完成华为云SWR容器镜像服务的登录
(2) 登录doocker hub,查看openjdk镜像,可以看到openjdk:19-jdk 支持 linux/386,linux/amd64,linux/arm/v5,linux/arm/v7,linux/arm64/v8,linux/mips64le,linux/ppc64le,linux/s390x 平台,因此platforms参数可以填写些平台中的一个或多个,也可以填写全部。push参数填写为true,即打包完之后就push到华为云SWR
(3) file参数指定Dockerfile的路径,此处为./dockerfiles/Dockerfile-nginx avatar

    # docker login,设置登陆到华为的swr
    - name: Log in to Huawei Cloud SWR
      uses: huaweicloud/swr-login@v2.1.0
      with:
        region: cn-north-4
        access-key-id: ${{ secrets.ACCESSKEY }}
        access-key-secret: ${{ secrets.SECRETACCESSKEY }}

    # 完成docker镜像打包,支持多个平台
    - name: Build Nginx image for linux/386,linux/amd64,linux/arm/v5,linux/arm/v7,linux/arm64/v8,linux/mips64le,linux/ppc64le,linux/s390x
      uses: huaweicloud/swr-multiplatform-build-action@v1.2.0
      with:
        image_tag: swr.cn-north-4.myhuaweicloud.com/hcloudcli/nginx:nginx-12-v1.0.0.1
        platforms: linux/386,linux/amd64,linux/arm/v5,linux/arm/v7,linux/arm64/v8,linux/mips64le,linux/ppc64le,linux/s390x
        use_latest_buildx: true
        push: true
        file: ./dockerfiles/Dockerfile-nginx

详情可参考 .github/workflows/build-nginx-for-multiplatform.yml
