Hands-On Cloud-Native Applications with Java and Quarkus

By: Francesco Marchioni

Overview of this book

Quarkus is a new Kubernetes-native framework that allows Java developers to combine the power of containers, microservices, and cloud-native to build reliable applications. The book is a development guide that will teach you how to build Java-native applications using Quarkus and GraalVM. We start by learning about the basic concepts of a cloud-native application and its advantages over standard enterprise applications. Then we will quickly move on to application development, by installing the tooling required to build our first application on Quarkus. Next, we’ll learn how to create a container-native image of our application and execute it in a Platform-as-a-Service environment such as Minishift. Later, we will build a complete real-world application that will use REST and the Contexts and Dependency injection stack with a web frontend. We will also learn how to add database persistence to our application using PostgreSQL. We will learn how to work with various APIs available to?Quarkus?such as Camel, Eclipse MicroProfile, and Spring DI. Towards the end, we will learn advanced development techniques such as securing applications, application configuration, and working with non-blocking programming models using Vert.x. By the end of this book, you will be proficient with all the components of Quarkus and develop-blazing fast applications leveraging modern technology infrastructure.

Adding Web Interfaces to Quarkus Services

So far, we have learned how to build a simple REST application with Quarkus and covered the actions that should be put in place to build, test, and deploy our application on a Kubernetes environment.

We could stop at this point and be happy with what we have achieved; however, there are still lots of milestones to reach. For example, we haven't used any web interfaces to access Quarkus services. As you will see in this chapter, Quarkus features some extensions that allow us to reuse standard enterprise APIs such as Servlets and web sockets. At the same time, you can use lighter JavaScript/HTML 5 frameworks as user interfaces for your services. We will explore both approaches in this chapter.

In this chapter, we will cover the following topics:

  • Adding web content to Quarkus applications
  • Running our application on Minishift
  • Adding...
