SAR-Propagate-CloudFormation-Tags
SAR app to propagate CloudFormation's stack tags to resources that are currently not propagated automatically - e.g. CloudWatch Logs. It also propagates stack tag updates to resources whose tags are not automatically updated - e.g. Step Functions, SQS.
Deploying to your account (via the console)
Go to this page and click the Deploy
button.
This app would deploy the following resources to your region:
- a
Propagate
Lambda function that propagates CloudFormation's tags to resources that aren't tagged automatically - a CloudWatch event pattern that triggers the
Propagate
function wheneverCloudFormation:CreateStack
andCloudFormation:UpdateStack
events are captured by CloudTrail - a
PropagateAll
Lambda function that iterates through all CloudFormation stacks in the region and propates their tags, this function is only triggered once, when you deploy the SAR app - a
Custom::LambdaInvocation
CloudFormation custom resource, which would trigger thePropagateAll
Lambda function during the deployment of this SAR app
Deploying via SAM/Serverless framework/CloudFormation
To deploy this app via SAM, you need something like this in the CloudFormation template:
PropagateCloudFormationTags:
Type: AWS::Serverless::Application
Properties:
Location:
ApplicationId: arn:aws:serverlessrepo:us-east-1:374852340823:applications/propagate-cfn-tags
SemanticVersion: <enter latest version>
To do the same via CloudFormation or the Serverless framework, you need to first add the following Transform
:
Transform: AWS::Serverless-2016-10-31
