I used Python for AWS Lambda function. You will be asked to provide a template - choose the upload option and select the stack YAML file, then click Next. The following commands will create and launch the stack, replace the parameters with your own values. I was trying to enable it in other more complicated ways. Once your stack is complete, go and find your stack’s new Lambda here. For who looking the similar workaround. Installation Guide. Creating a Stack. Lambda-backed custom resources. This month, Amazon added the AWS CloudFormation CLI and registry, which should increase the scope of resources supported in CloudFormation. CloudFormation to create change set and update stack; S3 to upload and store Serverless artifacts and Lambda source code; CloudWatch Logs to store Lambda execution logs; IAM to manage policies for the Lambda IAM Role; API Gateway to manage API endpoints; Lambda to manage Lambda functions; EC2 to execute Lambda in VPC. Serverless, a framework that facilitates seamless deployments of AWS Lambda functions, addresses the chicken and egg problem when deploying a CloudFormation stack that defines an AWS Lambda function and the S3 bucket in which it resides. The lambda-formation project is a small, slightly opinionated way to build a set of lambda handlers that are compatible with CloudFormation Custom Resources. sh - invokes the lambda from the command line.
