Micronaut function lambda for DynamoDB.

Building Micronaut AWSLambda native executable is quite easy and require 3 steps only:

1. Build JAR:

./gradlew micronaut-function-dynamodb:shadowJar

2. Build native executable via Docker:

docker build -t micronaut-function-dynamodb .

3. Extract native executable from container:

docker run --rm --entrypoint cat micronaut-function-dynamodb /home/application/function.zip > build/function.zip

You can run AWS emulator (SAM) locally to emulate and test deployment like it is AWS Lambda Cloud.

sam local start-api -t sam.yaml -p 3000

Example of event to send to lambda:

{
  "name": "Steeven King"
}
