Question

我的目标是在 subdomain.mydomain.com 创建一个指向 CloudFront CDN 的网站，该 CDN 分发运行 Express 的 Lambda，并呈现 S3 网站。我正在使用 AWS CDK 来执行此操作。

我有一个错误提示

[Error at /plants-domain] User: arn:aws:sts::413025517373:assumed-role/plants-pipeline-BuildCDKRole0DCEDB8F-1BHVX6Z6H5X0H/AWSCodeBuild-39a582bf-8b89-447e-a6b4-b7f7f13c9db1 is not authorized to perform: route53:ListHostedZonesByName

意思是：

[Error at /plants-domain] - 名为 plants-domain 的堆栈中的错误
User: arn:aws:sts::1234567890:assumed-role/plants-pipeline-BuildCDKRole0DCEDB8F-1BHVX6Z6H5X0H/AWSCodeBuild-39a582bf-8b89-447e-a6b4-b7f7f13c9db 是与我在执行 plants-pipeline 的 route53.HostedZone.fromLookup() 中的对象关联的假定角色的 ARN（但它是哪个对象？？）
is not authorized to perform: route53:ListHostedZonesByName 承担的角色需要额外的 Route53 权限

我相信此政策将允许相关对象查找托管区域：

const listHostZonesByNamePolicy = new IAM.PolicyStatement({
  actions: ['route53:ListHostedZonesByName'],
  resources: ['*'],
  effect: IAM.Effect.ALLOW,
});

使用 Route53.HostedZone.fromLookup() 的代码位于第一个堆栈 domain.ts 中。我的另一个堆栈使用 domain.ts 使用 CodePipelineAction.CloudFormationCreateUpdateStackAction 模板（见下文）

domain.ts


// The addition of this zone lookup broke CDK
const zone = route53.HostedZone.fromLookup(this, 'baseZone', {
  domainName: 'domain.com',
});

// Distribution I'd like to point my subdomain.domain.com to
const distribution = new CloudFront.CloudFrontWebDistribution(this, 'website-cdn', {
// more stuff goes here
});


// Create the subdomain aRecord pointing to my distribution
const aRecord = new route53.ARecord(this, 'aliasRecord', {
  zone: zone,
  recordName: 'subdomain',
  target: route53.RecordTarget.fromAlias(new targets.CloudFrontTarget(distribution)),
});

pipeline.ts


const pipeline = new CodePipeline.Pipeline(this, 'Pipeline', {
  pipelineName: props.name,
  restartExecutionOnUpdate: false,
});

// My solution to the missing AssumedRole synth error: Create a Role, add the missing Policy to it (and the Pipeline, just in case)
const buildRole = new IAM.Role(this, 'BuildRole', {
  assumedBy: new IAM.ServicePrincipal('codebuild.amazonaws.com'),
  path: '/',
});

const listHostZonesByNamePolicy = new IAM.PolicyStatement({
  actions: ['route53:ListHostedZonesByName'],
  resources: ['*'],
  effect: IAM.Effect.ALLOW,
});


buildRole.addToPrincipalPolicy(listHostZonesByNamePolicy);

pipeline.addStage({
  // This is the action that fails, when it calls `cdk synth`
  stageName: 'Build',
  actions: [
    new CodePipelineAction.CodeBuildAction({
      actionName: 'CDK',
      project: new CodeBuild.PipelineProject(this, 'BuildCDK', {
        projectName: 'CDK',
        buildSpec: CodeBuild.BuildSpec.fromSourceFilename('./aws/buildspecs/cdk.yml'),
        role: buildRole, // this didn't work
      }),
      input: outputSources,
      outputs: [outputCDK],
      runOrder: 10,
      role: buildRole, // this didn't work
    }),
    new CodePipelineAction.CodeBuildAction({
       actionName: 'Assets',
      // other stuff
    }),
    new CodePipelineAction.CodeBuildAction({
      actionName: 'Render',
      // other stuff
    }),
  ]
})

pipeline.addStage({
  stageName: 'Deploy',
  actions: [
    // This is the action calling the compiled domain stack template
    new CodePipelineAction.CloudFormationCreateUpdateStackAction({
      actionName: 'Domain',
      templatePath: outputCDK.atPath(`${props.name}-domain.template.json`),
      stackName: `${props.name}-domain`,
      adminPermissions: true,
      runOrder: 50,
      role: buildRole, // this didn't work
    }),
    // other actions
  ]
});

不幸的是，通过上述配置，我仍然收到相同的错误：

[Error at /plants-domain] User: arn:aws:sts::413025517373:assumed-role/plants-pipeline-BuildCDKRole0DCEDB8F-1BHVX6Z6H5X0H/AWSCodeBuild-957b18fb-909d-4e22-94f0-9aa6281ddb2d is not authorized to perform: route53:ListHostedZonesByName

使用 Assumed Role ARN，是否可以追踪缺少权限的对象？还有其他方法可以解决我的 IAM/AssumedUser 角色问题吗？

基于错误，管道角色（它会在阶段或行动中工作......）

默认a new role is being created for the pipeline：

<块引用>

角色？

类型：IRole（可选，默认：将创建一个新的 IAM 角色。）

此管道要承担的 IAM 角色。

相反，当您构建管道时，请在此处添加 buildRole：

const pipeline = new CodePipeline.Pipeline(this, 'Pipeline', {
  pipelineName: props.name,
  restartExecutionOnUpdate: false,
  role: buildRole
});

根据您的管道，您从未将角色分配给相关的阶段操作 according to the docs：

pipeline.addStage({
  stageName: 'Deploy',
  actions: [
    // This is the action calling the compiled domain stack template
    new CodePipelineAction.CloudFormationCreateUpdateStackAction({
      ...
      role: buildRole, // this didn't work
    }),
    // other actions
  ]
});

应该是：

pipeline.addStage({
  stageName: 'Deploy',
  actions: [
    // This is the action calling the compiled domain stack template
    new CodePipelineAction.CloudFormationCreateUpdateStackAction({
      ....
      deploymentRole: buildRole
    }),
  ]
});

为什么是 deploymentRole 而不是 role，没人知道。

假定角色无权执行：route53:ListHostZonesByDomain；将 Route53 策略添加到 CodePipeline CodeBuildAction 的假定规则
