Hands-On Cloud Development with WildFly

By: Tomasz Adamski

Overview of this book

The book starts by introducing you to WildFly Swarm—a tool that allows you to create runnable microservices from Java EE components. You’ll learn the basics of Swarm operation—creating microservices containing only the parts of enterprise runtime needed in a specific case. Later, you’ll learn how to configure and test those services. In order to deploy our services in the cloud, we’ll use OpenShift. You’ll get to know basic information on its architecture, features, and relationship to Docker and Kubernetes. Later, you’ll learn how to deploy and configure your services to run in the OpenShift cloud. In the last part of the book, you’ll see how to make your application production-ready. You’ll find out how to configure continuous integration for your services using Jenkins, make your application resistant to network failures using Hystrix, and how to secure them using Keycloak. By the end of the book, you’ll have a functional example application and will have practical knowledge of Java EE cloud development that can be used as a reference in your other projects.

Summary

In this chapter, you learned the build infrastructure provided by OpenShift. You then learned to use source-to-image build, which abstracts away the details of Kubernetes internals from the developer and lets them build the image based solely on code with minimal configuration.

In the second part of this chapter, you learned about the pipeline build, which, effectively, is a way to integrate Jenkins pipelines with OpenShift infrastructures. You also learned how to create the pipeline build and the basics of the DPL syntax. Hence, you were able to create a CD pipeline for your petstore's pricing-service.
