AWS Lambda with Single CloudFormation Template

This is just a quick snippet of CloudFormation template to deploy a Python 3.7 Lambda function embedded in the template. The source code inside ZipFile can contain up to 4KB.

# CloudFormation template
AWSTemplateFormatVersion: 2010-09-09
Resources:
  LambdaCode:
    Type: AWS::Lambda::Function
    DependsOn:
      - LambdaRole
      - LambdaPolicy
    Properties:
      Code:
        ZipFile: |
          import boto3
          def handler(event, context):
            ...
      Role: !GetAtt LambdaRole.Arn
      Runtime: python3.7
      Handler: index.handler

Note: the depending LambdaRole is not included, but can be found easily here .
