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.

Kick-starting applications using the Quarkus online application

Another option for bootstrapping your Quarkus application is using the online application, which is available at the following address:

By landing on that page, you will be able to generate a basic project with an initial endpoint, as well as all the extensions that you checked out in the user interface:

As shown in the preceding screenshot, by default, just the RESTEasy extension is selected. From the top-left corner of the interface, you can configure your project coordinates (groupId, artifactId) and the build tool, which can be either Maven or Gradle. More options are available through the CONFIGURE MORE OPTIONS panel, which lets you configure the package name and the version for the project.

By scrolling down the list of available extensions, you can also choose to experiment with alternative...
