⁠Random Number Generator Service

This is a very simple Spring Boot service which just generates a random number and returns it as JSON:

curl -sL http://localhost:8080/ | jq .
{
  "random": 838265052,
  "id": "58da4c5b-ba06-438e-84f8-1a30581baeb8"
}

Start the service with either ./mvnw spring-boot:run or, after building with ./mvnw package, with java -jar target/random-generator-*.jar

Refer to the Image Builder⁠ pattern in the Kubernetes Patterns books example repository⁠ how this example is build from within a Kubernetes cluster.
