Project to explore GitHub Actions, AWS CDK, and AWS Lambda.

Base app is written in Go and simply outputs an IP address of a function visitor.

Local Lambda development with Amazon Sam

• install Amazon Sam
• run sam local start-api (on mac os DOCKER_HOST=unix://$HOME/.docker/run/docker.sock sam local start-api)
• visit http://127.0.0.1:3000/hello

Creates AWS infrastructure with Amazon CDK

• npm install -g aws-sdk
• run make build-and-zip to create a binary. It's required to create a Lambda function
• run cd cdk
• run cdk bootstrap
• run AWS_ACCOUNT_ID=1111 AWS_REGION=us-east1 cdk deploy. It will eventually output values required to run a pipeline
• run cdk destroy to delete created resources

CI/CD with GitHub Actions

• pipeline config is located in .github/workflows
• pipeline requires the following secrets to work: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_LAMBDA_ARN
• secrets are added on github.com/user/repository/settings/secrets/actions under Repository secrets
