在 GitHub Actions 的仓库中自动化、自定义和执行软件开发工作流程。 您可以发现、创建和共享操作以执行您喜欢的任何作业（包括 CI/CD），并将操作合并到完全自定义的工作流程中。

Action 能干啥？都能干，前段时间还有人挖矿

下面所有的用户名和仓库用 laowang 和 zhangshan 代替

Actions secrets

一些不方便的隐私的东西可以放进去，然后用环境变量代替

那么 laowang 是怎么发出的呢？

看了这么多，有点累了，上点才艺吧

越看越累😂，来把英雄联盟手游，打完了继续

对了，万一我设置了几个任务，但是他们是同步进行的，会报错，必须一个一个来怎么办？

# Copy File
COPY ${TARGETPLATFORM}/code-server.rpm /www/ # 上面我们创建并下载了软件包，所以可以直接复制

RUN rpm -ivh /www/code-server.rpm

还有一些复杂度挺高的，欢迎大家来我 github 参观 PHP_Docker

思考

怎么用 action 做到监控别的仓库更新自己也运行？除了发送信号还有别的方案吗？
