manually build app using maven, start mysql & kafka(please look into the compose file for any other dependancy)
just docker compose up
OR just kubectl apply -f k8s/<everything>.yaml
to get it up & running in a cluster.
Note: if deploying on a k8s cluster make sure to have kafka setup(Strimzi is cool)[https://strimzi.io/quickstarts/]
If everything went right the app should run at http://localhost:8080/users
