Question

我真的不明白缓存是如何工作的，以及我如何才能真正加快我的 CI/CD。我想让它在不到 2 分钟的时间内运行，但我得到的只是一条 30m/40m/1h 的管道。

我已经尝试了很多缓存技术（全局缓存，每个作业缓存）我不会在这里写下所有内容（我现在正在这 3 天里工作，所以我尝试了很多东西，也阅读了很多东西......）。

该项目是一个 .NET MVC 项目，通过 NPM 进行了一些静态捆绑。

CI/CD 在 Windows Server 2008 R2 上运行。没有泊坞窗图像。只是 C:\gitlab_runner 文件夹中的 gitlab-runner，所有工具都本地安装在标记为 deploy-vmdev

的机器上

（项目名为Iom.Site，保存在Iom.Site文件夹内）

我能做的最好的就是这个（但它平均运行 30m，有时它会因为依赖缓存、node_modules 和包不存在而中断。）：

最后我在 gitlab ci wiki 上找到了这个：

缓存是一种优化，但不能保证总是有效。您需要准备好在需要它们的每个作业中重新生成任何缓存文件。

并以这种方式改变了我的管道：

stages:
  - build_app
  - package
  - deploy

build_static_files:
  stage: build_app
  before_script:
    - cd Iom.Site
    - if(-Not(Test-Path node_modules)){npm install} #Installiamo le dipendenze di npm solo se non presenti
  only:
    changes:
      - Iom.Site\scripts\bundle\**\*
      - Iom.Site\scripts\react\**\*
      - Iom.Site\scss\**\*

    policy: pull-push
  script:
    - gulp build
    - cd ..

  artifacts:
    paths:

GITLAB CI/CD 使用缓存或工件提高流水线速度？
