【中文标题】AWS cloudformation 嵌套堆栈因模板 URL 失败【英文标题】:AWS cloudformation nested stacks failed by template URL 【发布时间】:2021-12-29 19:20:01 【问题描述】:我是 cloudformation 的新手,但在当前项目中有一个模板,该模板在一个唯一文件中包含所有资源,我们尝试使用嵌套堆栈选项将多个文件分开。当我尝试部署模板时,下一条消息执行失败:
$ aws s3 cp testing-substack.yml s3://gitlab-cicd
upload: ./testing-substack.yml to s3://gitlab-cicd/testing-substack.yml
$ aws cloudformation package --template-file testing-mainstack.yml --s3-bucket gitlab-cicd --output-template testing-packstack.yaml
Unable to upload artifact substack-amp.yml referenced by TemplateURL parameter of SubstackA resource.
TemplateURL parameter of SubstackA resource is invalid. It must be a S3 URL or path to CloudFormation template file. Actual: /builds/project-0/substack-amp.yml
接下来包含两个模板(lambda 函数只有一个“Hello world”:
testing-mainstack.yml
测试A
Resources:
SubstackA:
Type: 'AWS::CloudFormation::Stack'
Properties:
TemplateURL: testing-substack.yml
测试 B
Resources:
SubstackA:
Type: 'AWS::CloudFormation::Stack'
Properties:
TemplateURL: s3://gitlab-cicd/testing-substack.yml
子栈模板:testing-substack.yml
TestingSubLambda:
Type: AWS::Serverless::Function
Properties:
Description: "Testing lambda inside substack"
CodeUri: ./
Handler: lambda-two.lambda_handler
Runtime: python3.8
FunctionName: TestingSubLambda
# Role: arn:aws:iam::000365055762:role/lambda-essential-role

# Events:

如何确定将子堆栈定义为主堆栈的正确方法?
【问题讨论】:
【参考方案1】:TemplateURL
应该写成 S3 中的 URL,因此是https://...
。
在this doc,写成:
TemplateURL: https://s3.amazonaws.com/cloudformation-templates-us-east-1/S3_Bucket.template

【参考方案2】:我修复了@Shimo响应的问题,另外,使用SAM客户端。
子栈 A
AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Resources:
TestingSubLambdaA:
Type: AWS::Serverless::Function
Properties:
Description: "Testing lambda mnain substack"
CodeUri: lambda-one/
Handler: lambda-one.lambda_handler
Runtime: python3.8
FunctionName: TestingSubLambdaA
Timeout: 480
子栈 B
AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Resources:
TestingSubLambdaB:
Type: AWS::Serverless::Function
Properties:
Description: "Testing lambda secondar substack"
CodeUri: lambda-two/
Handler: lambda-two.lambda_handler
Runtime: python3.8
FunctionName: TestingSubLambdaB
Timeout: 480
主栈
Resources:
SubstackA:
Type: 'AWS::CloudFormation::Stack'
Properties:
TemplateURL: https://<S3-BUCKET>.s3.<AWS-REGION>.amazonaws.com/test-subkstack-a.yml
TimeoutInMinutes: 5
SubstackB:
Type: 'AWS::CloudFormation::Stack'
Properties:
TemplateURL: https://<S3-BUCKET>.s3.<AWS-REGION>.amazonaws.com/test-subkstack-b.yml
TimeoutInMinutes: 5
最后,我在发送到 S3 容器之前打包子堆栈模板。
sam package -t testing-substack-a.yml --s3-bucket <S3-BUCKET> --output-template-file test-subkstack-a.yml --region ap-northeast-1
sam package -t testing-substack-b.yml --s3-bucket <S3-BUCKET> --output-template-file test-subkstack-b.yml --region <AWS-REGION>
aws s3 cp test-subkstack-a.yml s3://<S3-BUCKET>
aws s3 cp test-subkstack-b.yml s3://<S3-BUCKET>
sam package -t testing-mainstack.yml --s3-bucket <S3-BUCKET> --output-template-file testing-packstack.yml --region <AWS-REGION>
sam deploy --template-file testing-packstack.yml --stack-name TestingStackDeploy --region <AWS-REGION> --capabilities CAPABILITY_AUTO_EXPAND CAPABILITY_IAM

是否有任何东西可以将 AWS::ElasticBeanstalk::Environment 链接到它创建的嵌套堆栈?
