Aliyun容器镜像仓库

https://cn.aliyun.com/

• 登录Aliyun；
• 在产品与服务中找到 弹性计算--容器镜像服务；
• 创建镜像仓库；
• 命名空间可以理解为Docker Hub的username， 仓库名称即repository；
• 创建好后点击仓库进入，查看操作指南获取regitry URL。

GitHub Actions

https://docs.github.com/en/actions

• 在GitHub repository中点击Actions选项卡创建workflow（workflow配置文件默认为.yml并且存放在根目录.github/workflows中）；
• 创建GitHub Secrets存储registry，username及password等信息；
• 参考代码如下：

name: Docker Image CI
# 触发条件：当master branch触发push（push，merge Pull Request）时，弱docker文件夹下的文件有更新，则触发。
on:
  push:
    branches:
      - master
    paths:
      - 'docker/**'

defaults:
  run:
    shell: bash
    working-directory: './docker'

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout Dockerfile
        uses: actions/checkout@v2
      # 使用Docker官方制作的action
      # https://github.com/marketplace/actions/build-and-push-docker-images
      - name: Build and Push Docker Iamge
        uses: docker/build-push-action@v1
        with: 
          registry: ${{ secrets.ALI_DOCKER_HUB_REGISTRY }}
          username: ${{ secrets.ALI_DOCKER_HUB_USN }}
          password: ${{ secrets.ALI_DOCKER_HUB_PWD }}
          repository: username/repository
          tag_with_sha: true
          path: 'docker'

      # 使用Aliyun操作指南提供的命令
      # - name: Build Docker image
      #   run: |
      #     docker build -t locale:tag .
          
      # - name: Push to Ali Docker Repository
      #   run: |
      #     docker login -u ${{ secrets.ALI_DOCKER_HUB_USN }} -p ${{ secrets.ALI_DOCKER_HUB_PWD }} ${{ secrets.ALI_DOCKER_HUB_REGISTRY }}
      #     docker tag locale ${{ secrets.ALI_DOCKER_HUB_REGISTRY }}/username/repository:tag
      #     docker push ${{ secrets.ALI_DOCKER_HUB_REGISTRY }}/username/repository:tag
