Warehouse example application with Kafka and Quarkus

This repository contains an example application for orders processing in a warehouse, with the purpose of trying and showing different technologies. This is a diagram showcasing in high level how the application works

How it's implemented?

This example microservices application is implemented combining quarkus and strimzi. Quarkus is a Java framework used to code the microservices and Strimzi is the best kubernetes operator to manage kafka deployments

How to run it?

The only prerequisite is having an openshift cluster with strimzi installed. You can install strimzi with

make install-strimzi

Package the application

make login_container_registry
oc new-project warehouse
make container
make deployment_bundle

Deploy the application

oc apply -f kubefiles

You can check the application is running with

oc get pod
