Quarkus Cookbook

Chapter 1. Quarkus Overview

Kubernetes is becoming the de facto platform to deploy our enterprise applications nowadays. The movement to containers and Kubernetes has led to changes in the way we code, deploy, and maintain our Java-based applications. You can easily get yourself in trouble if you containerize and run a Java application without taking proper measures. Containers in Pods (a Kubernetes term) are the basic units in Kubernetes, so it is very important to have a good understanding of how to containerize a Java-based application correctly to avoid pitfalls, wasted work, and extra hours of frustration.

Quarkus is a cloud-native framework with built-in Kubernetes integration. It is an open source stack, released under the Apache License 2.0, that helps you create Kubernetes-native applications tailored for GraalVM and OpenJDK HotSpot. It is built on top of popular libraries and technologies such as Hibernate, Eclipse MicroProfile, Kubernetes, Apache Camel, and Eclipse Vert.x.

The benefits of Quarkus include easy integration with Docker and Kubernetes, quick startup time, low resident set size (RSS) memory, and increased developer productivity. In this introductory chapter, we’ll take a quick look Quarkus—what it is, the problems it solves, how it integrates with Kubernetes, why developers enjoy working with it, and some of its most noteworthy features.
