使用 aws cdk 創建 elasticbeanstalk 實例

Question

我正在使用以下代碼創建一個 elasticbeanstalk 實例，但是，當我嘗試部署時，它拋出No application with name pythonService is found

import cdk = require('@aws-cdk/core');
import ebs = require('@aws-cdk/aws-elasticbeanstalk');

export class DevOpsStack extends cdk.Stack {
  constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const webAppName: string = 'pythonService';

    const webApp = new ebs.CfnApplication(this, webAppName);

    const pythonServiceS3BucketName : string = 'my-bucket-name'
    const pythonServiceArchiveName : string = 'my-awesome-app.zip'
    const webAppVersion = new ebs.CfnApplicationVersion(this, 'pythonServiceVer', {
      applicationName: webAppName,
      sourceBundle: {
        s3Bucket: pythonServiceS3BucketName,
        s3Key: pythonServiceArchiveName
      }
    });

    const options: ebs.CfnEnvironment.OptionSettingProperty[] = [{
      namespace: 'aws:ec2:vpc',
      optionName: 'VPCId',
      value: 'a-vpc-id'
    }, {
      namespace: 'aws:ec2:vpc',
      optionName: 'Subnets',
      value: 'a-subnet-id'
    }];

    const webAppEnv = new ebs.CfnEnvironment(this, 'pythonServiceEnv', {
      applicationName: webAppName,
      solutionStackName: '64bit Amazon Linux 2018.03 v2.9.2 running Python 3.6',
      optionSettings: options
    });
  }
}

我相信這一切，因為它試圖部署CfnApplicationVersion創建之前CfnApplication 。

此外，它生成的 cloudformation 模板在應用程序之前沒有!Ref ：

Resources:
  pythonService:
    Type: AWS::ElasticBeanstalk::Application
    Metadata:
      aws:cdk:path: DevOpsStack/pythonService
  pythonServiceVer:
    Type: AWS::ElasticBeanstalk::ApplicationVersion
    Properties:
      **ApplicationName: pythonService**
      SourceBundle:
        S3Bucket: ...
        S3Key: ...

Answer 1

您必須手動構建依賴關系樹，因為 CfnApplication 和 CfnApplicationVersion 之間沒有引用。 因此，添加 CfnApplication 作為依賴項以確保它在 CfnApplicationVersion 之前部署：

webAppVersion.addDependsOn(webApp);

Answer 2

我遇到了類似的問題，並發現Chris的addDependsOn建議運行良好。

但是，僅添加此修復程序將部署示例應用程序，因為您的環境未引用特定版本。 除了dependsOn修復，我相信你需要添加 versionLabel to your webAppEnv`：

    const webAppEnv = new ebs.CfnEnvironment(this, 'pythonServiceEnv', {
      applicationName: webAppName,
      solutionStackName: '64bit Amazon Linux 2018.03 v2.9.2 running Python 3.6',
      optionSettings: options,
      versionLabel webAppVersion.ref
    });
