AWS CDK

Quick start CDK sample code to add Event to run Lambda

  • add CloudWatch Event to trigger the Lambda by cdk deploy
  • refer existing Lambda deployed by dotnet lambda deploy-function
  • using Official CDK Workshop: https://cdkworkshop.com/40-dotnet.html

Setup CDK

# setup node by nodenv https://github.com/nodenv/nodenv
nodenv --version
> nodenv 1.3.2

nodenv install 12.16.2
nodenv global 12.16.2

nodenv versions
> * 12.16.2
node --version
> v12.16.2

# Installing the AWS CDK
npm install -g aws-cdk

# or upgrade
npm outdated -g
npm update -g

cdk --version
> 1.36.0 (build 47c9919)
# in case command not found error, try "nodenv rehash"

Create initial app

cdk init sample-app --language csharp
# check generated README to find useful commands

dotnet restore src/CdkWorkshop
dotnet build src/CdkWorkshop

export AWS_PROFILE=your-profile
cdk synth

# (optional?) the first time you deploy
# create S3 bucket cdktoolkit-... and Cfn Stack CDKToolkit
# cdk bootstrap

# create CloudFormation Stack
cdk deploy

Develop

cd src/CdkWorkshop/
# NOTE: cdk init app create simple app without SNS SQS

# update the code in CdkWorkshopStack.cs

cdk diff
cdk deploy
  • it seems there is chicken and egg problem around lambda permission
  • first you create lambda role from cdk, next dotnet deploy lambda
  • and create rule from cdk, then manually add trigger from console

Clean up

cdk destroy
