Preface

As an application developer, you can use Red Hat build of Quarkus to create microservices-based applications written in Java that run in OpenShift and serverless environments. Applications compiled to native executables have small memory footprints and fast startup times.

This guide shows you how to use Apache Maven to create, test, package, and run a simple Quarkus project that exposes a hello HTTP endpoint. To demonstrate dependency injection, this endpoint uses a greeting bean.
