我有一个简单的 AWS CodePipeline,其标准“源”->“构建”->“部署”管道阶段运行良好,我正在尝试添加自己的自定义最终管道阶段,即单个 AWS Lambda 函数。问题是我的最后一个自定义 Lambda 函数运行了多次,并且在很长一段时间后出现错误,并显示以下消息:

请参阅随附的整个管道的屏幕截图:

当管道到达最后一步时,它会以“蓝色(进行中)”状态旋转很长时间,然后显示错误,如下所示:

这是我的 Lambda 函数代码:

from __future__ import print_function
import hashlib
import time
import os
import boto3
import json
from botocore.exceptions import ClientError

def lambda_handler(event, context):

# Test
AWS_ACCESS_KEY = ASDF1234
AWS_SECRET_KEY = ASDF1234
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
sqs_resource_connection = boto3.resource(
'sqs',
aws_access_key_id = AWS_ACCESS_KEY,
aws_secret_access_key = AWS_SECRET_KEY,
region_name = 'us-west-2'
)

# Get the queue handle
print("Waiting for notification from AWS ...")
queue = sqs_resource_connection.get_queue_by_name(QueueName = SQS_TESTING_OUTPUT_STATUS_QUEUE_NAME)
messageContent = ""
cnt = 1

RECIPIENTS = [YOU]

# If necessary, replace us-west-2 with the AWS Region you're using for Amazon SES.
AWS_REGION = "us-east-1"

# The subject line for the email.
SUBJECT = "Test Case Results"

# The email body for recipients with non-HTML email clients.
BODY_TEXT = ("Test Case Results Were ...")

# The HTML body of the email.
BODY_HTML = """<html>

# The character encoding for the email.
CHARSET = "UTF-8"

# Create a new SES resource and specify a region.
client = boto3.client('ses', region_name=AWS_REGION)

# Try to send the email.
try:
# Provide the contents of the email.
response = client.send_email(
Destination={
'ToAddresses': RECIPIENTS,

#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'})
print(e.response['Error']['Message'])
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 触发一次并返回,以便管道能够正确完成。

最佳答案

您缺少 Lambda FunctionCodePipeline 服务之间的重要集成。

您必须通知 CodePipeline 自定义步骤的结果,无论成功与否 - 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();
}

这种集成是这样设计的,因为人们可能希望与外部作业工作人员集成,其中他们的 Lambda 启动该工作人员(例如审批流程),然后该工作人员控制并决定整个步骤是否成功或失败。
