angular - 您如何编写用于 NodeJS 和 AWS CodeBuild 的 buildspec.yml？

Question

我有一个为 Angular 前端提供服务的 NodeJS 应用程序，这个应用程序是使用 AWS Elastic Beanstalk 部署的。如果我直接将 .zip 文件上传到 Elastic Beanstalk，它将包含:

\dist
request-map.js
credentials.json
server.js

这已经过测试并且效果很好。但现在我想要一个 CD 管道

当您构建 Angular 应用程序( ng build )时，它会将所有工件编译成 \dist项目根目录下的文件夹。我已经成功地创建了一个持续交付管道，但为了让它工作，我必须提交 \dist文件夹到我的代码存储库。这显然不理想。

为了改进我的架构，我知道我必须创建一个构建阶段。我已经成功添加了构建阶段，并且它在我的 buildspec.yml 上运行良好文件，但是当我导航到我的域时，出现错误:

Error: ENOENT: no such file or directory, stat '/var/app/current/dist/my-angular-app/index.html'

这是我的 buildspec.yml 文件

# Do not change version. This is the version of aws buildspec, not the version of your buldspec file.
version: 0.2
phases:
  pre_build:
    commands:
      - echo Installing source NPM dependencies...
      - npm install
  build:
    commands:
      - echo Build started on `date`
      - echo Compiling the dist folder
      - npm run-script build
  post_build:
    commands:
      - echo Build completed on `date`
# Include only the files required for your application to run.
artifacts:
  files:
    - index.js
    - dist/**/*
    - request-map.js
    - credentials.json
    - node_modules/**/*

与 AWS 相关的所有其他配置项都是默认值。

我查了 /var/app/current (工件被写入的地方)在我的 EC2 实例上，除了 dist 文件夹外，所有东西似乎都被复制了？？？我的设置有什么问题？

以下是来自 AWS CodeBuild 的日志

Answer 1

这是因为我没有将部署步骤指向 CodeBuild 步骤的工件。您将在 CodePipeline 中看到这一点。如果您不告诉 AWS 您的工件包的名称是什么，它就不知道要部署什么。您在 CodeBuild 配置中设置 CodeBuild 工件/输出的名称。
