AWS CodePipeline 自定义 Lambda 函数永远运行 Returns

Question

我有一个简单的 AWS CodePipeline，标准 "Source" -> "Build" -> "Deploy" 管道阶段工作正常，我正在尝试添加我自己的自定义最终管道阶段这是单个 AWS Lambda 函数。问题是我的最后一个自定义 Lambda 函数运行了很长时间后，出现以下消息的错误：

整个流水线请看附件截图：

当管道到达最后一步时，它会在 "Blue ( In-Progress )" 状态下旋转很长时间，然后显示错误，如下所示：

这是我的 Lambda 函数代码：

    SQS_TESTING_OUTPUT_STATUS_QUEUE_NAME = 'TestingOutputQueue'

    # Get the code pipeline
    code_pipeline = boto3.client('codepipeline')

    # Get the job_id
    for key, value in event.items():
        print(key,value)
    job_id = event['CodePipeline.job']['id']
    DATA = json.dumps(event)

    # Create a connection the SQS Notification service

    )

    # Get the queue handle

            # following line
            #ConfigurationSetName=CONFIGURATION_SET,
        )
    # Display an error if something goes wrong.
    except ClientError as e:
        code_pipeline.put_third_party_job_failure_result(jobId=job_id, failureDetails={'message': message, 'type': 'JobFailed'})
        code_pipeline.put_job_failure_result(jobId=job_id, failureDetails={'message': message, 'type': 'JobFailed'})

    else:
        code_pipeline.put_third_party_job_success_result(jobId=job_id)
        code_pipeline.put_job_success_result(jobId=job_id)
        print("Email sent! Message ID:"),
        print(response['MessageId'])

    print('Function complete.')   
    return "Complete."

如何让 Lambda 触发一次并 return 以便管道能够正常完成。谢谢！

您缺少 Lambda Function 和 CodePipeline 服务之间的重要集成。

您必须通知 CodePipeline 您的自定义步骤的结果，无论它是否成功 - 请参阅下面的示例。

报告成功：

function reportSuccess(job_id) {
  var codepipeline = new AWS.CodePipeline();
  var params = {
    jobId: job_id,
  };
  return codepipeline.putJobSuccessResult(params).promise();
}

报告失败：

function reportFailure(job_id, invoke_id, message) {
  var codepipeline = new AWS.CodePipeline();
  var params = {
    failureDetails: {
      message: message,
      type: 'JobFailed',
      externalExecutionId: invoke_id,
    },
    jobId: job_id,
  };
  return codepipeline.putJobFailureResult(params).promise();
}

以这种方式设计集成是因为人们可能希望与外部工作人员集成，其中他们的 Lambda 启动该工作人员（例如，批准流程），然后该工作人员控制并决定是否完成整个步骤成功或失败。
