aws cloudformation package --template-file sam.yaml --output-template-file target/output-sam.yaml --s3-bucket lambda-cfn

aws cloudformation deploy --template-file target/output-sam.yaml --stack-name spring-boot-lambda --capabilities CAPABILITY_IAM

aws cloudformation describe-stacks --stack-name spring-boot-lambda

To build and run from a packaged jar locally:

mvn spring-boot:run

or

mvn clean package -Dboot
java -jar target/spring-boot-lambda-1.0.0-SNAPSHOT.jar

To build the image. First build the application, then build the docker image
