AWS CloudFormation thread manager

Build Status

The CloudFormation doesn't manage or check resource creation limits during the deployment. The macro helps to deal with AWS API throttling during creating a lot of resources e.g. DynamoDB tables via CloudFormation. It creates different resource queues using DependsOn statement.

How to deploy the macro

  1. clone the repo

git clone https://github.com/vadymbat/aws-cf-concurrency-manager.git

  1. prepare CloudFormation template

aws cloudformation package --s3-bucket <your-s3-bucket> --template-file macro_template.yaml --output-template-file cf_concurrency_macro.yaml

  1. deploy the CloudFormation macro

aws cloudformation deploy --template-file cf_concurrency_macro.yaml --stack-name cf_concurrency_macro

How to use in your CloudFormation template

  1. add "Transform" statement Transform: CfConcurrencyMacro
  2. put ConcurrencyNumber: <int> to the root level of your template to set in how many threads your infrastructure will be deployed
  3. (optional) fill CommonDependancies: ["<ResourceLogicalId>"] list of the resources which are dependencies of all resources in the stack

Check the example template for more details.
