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.

Setting up Docker

Docker is a tool that lets us simplify the creation and execution of containers in our environment. Each container, in turn, wraps up an application and its dependencies into a single standardized unit that includes everything it needs to run, that is, the system tools, code, and other required libraries. This guarantees that your application will always execute in the same way by sharing a simple container image. Docker is available in two versions:

  • Community Edition (CE): The Docker CE, which we will be using in this book, is ideal for developers and small teams looking for a quick start with Docker and container-based applications.
  • Enterprise Edition (EE): The EE features additional capabilities such as a certified infrastructure, image management, and image security scanning.

Although we will be using the Community version of Docker, this isn't going...
