buildspec.yml放在CDK还是源码根目录哪种方式比较好

Which way is better to put buildspec.yml, in CDK or root directory of the source code

CDK包源码包中添加buildspec.yml哪种方式比较好?

上下文

现在有两种添加构建规范代码的方法。

第一个选项是将其添加到源代码包中,如前所述here:“如果将构建规范作为源代码的一部分,默认情况下,构建规范文件必须命名为buildspec.yml 并放置在源目录的根目录中。"

但是,这个选项感觉不太好,因为构建规范实际上与服务实现无关,而更多地与如何部署服务有关。而且它更特定于 AWS。就是感觉不应该是源码包的一部分

第二个选项是将其添加到CDK中。但我真的不喜欢内联构建规范代码,因为它看起来很臃肿,只是一个例子:

const buildProject = new codebuild.PipelineProject(this, 'project', {
      environment: {// I guess I need to select ubuntu and image 4.0},
      buildSpec: codebuild.BuildSpec.fromObject({
        version: '0.2',
        phases: {
          build: {
            commands:['
              version: 0.2
                phases:
                    install:
                        runtime-versions:
                            docker: 18
                    build:
                        commands:
                            - apt-get install jq -y
                            - ContainerName="tnkDjangoContainer"
                            - ImageURI=$(cat imageDetail.json | jq -r '.ImageURI')
                            - printf '[{"name":"CONTAINER_NAME","imageUri":"IMAGE_URI"}]' > imagedefinitions.json
                            - sed -i -e "s|CONTAINER_NAME|$ContainerName|g" imagedefinitions.json
                            - sed -i -e "s|IMAGE_URI|$ImageURI|g" imagedefinitions.json
                            - cat imagedefinitions.json

                artifacts:
                    files:
                        - imagedefinitions.json
              
              ',         
            ],
          },
        }
      })
    });

构建规范代码会变得更复杂、更长。

所以我打算添加:

    const buildspecFile = FS.readFileSync('./config/buildspec.yml', 'utf-8');  
    const buildspecFileYaml = YAML.parse(buildspecFile,{
          prettyErrors:true
        }
    );

    const codeBuildProject = new CodeBuild.PipelineProject(this, "Build", {
      projectName: "Build",
      environment: {
        buildImage: CodeBuild.LinuxBuildImage.AMAZON_LINUX_2_2,
        privileged: true,
      },
      environmentVariables: {
        CLUSTER_NAME: {
          value: `${props.fargateCluster.clusterName}`,
        },
        ECR_REPO_URI: {
          value: `${ecrRepo.repositoryUri}`,
        },
      },
      buildSpec: CodeBuild.BuildSpec.fromObjectToYaml(buildspecFileYaml),
    });

哪种方式更好?我不认为 AWS CodePipeline 支持从 CDK 包中的本地文件读取?我现在只看到三个选项:

Which way is better to add buildspec.yml, in CDK package or source code package?

通过。这取决于用例和开发人员偏好。

I don't think AWS CodePipeline support read from a local file in CDK package yet?

是的,但您可以使用语言功能自行将本地 yaml buildspec 文件内联到 CDK 输出中。读取并解析文件,然后将结果传递给fromObject方法:

import * as yaml from 'yaml'; // https://www.npmjs.com/package/yaml

const stringified: string = fs.readFileSync(path.join(__dirname, './buildspec.yml'), { encoding: 'utf-8', });
const parsed: any = yaml.parse(stringified);

new codebuild.Project(this, 'MyProject', {
  buildSpec: codebuild.BuildSpec.fromObject(parsed),
});
