我已经用上 Actions 了，在我看来它不仅仅是一个 CI 工具，它更像一个「工作流控制器」。

你可以把它打造为 CI、Bot、跳板机、文章发布器、Issues 统计器...任何你需要的工具或平台。

Actions 事件继承于之前的 API/Webhooks，自身提供了 Docker 环境，这意味着你拥有了无限编程能力的 “工作流定制权”。

比如，在实际的使用中，我的 angular-admin (web)、nodepress (nodejs) 两个项目的部署流程，

前者在 Actions 中的流程为：

测试（前提） -> 编译 -> 打包 -> 压缩 -> 通过 scp 将压缩包传给生产机 -> 执行生产机部署脚本 -> 完成部署

代码：

      - name: Copy file to server
        uses: appleboy/scp-action@master
        with:
          timeout: 3m
          overwrite: true
          host: ${{ secrets.HOST }}
          username: ${{ secrets.USER }}
          password: ${{ secrets.PASSWORD }}
          source: ./dist.tar.gz

      - name: Exec deploy script with SSH
        uses: appleboy/ssh-action@master

          password: ${{ secrets.PASSWORD }}
          script: |
            sh ${{ secrets.WWW_PATH }}/angular-admin/.deploy/main.sh

后者在 Actions 中的流程为：

测试 -> 编译 -> 构建测试 -> 执行生产机部署脚本 -> 完成部署
