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.

Configuring Continuous Deployment in OpenShift environments

After this quick theory recap, now let's return to our cluster and configure CD for our application.

At the beginning of this chapter, we described the source-to-image build, which we have used in previous chapters. We also hinted that there is a pipeline build available. As you probably have guessed by now, this is the kind of build that we will use to implement CD of our services.

The pipeline build uses the Jenkins server to configure the pipeline configuration. Before moving further, let's introduce it quickly.

Introducing Jenkins

Jenkins is an open source software automation server. It allows for pipeline creation and provides the relevant syntax. So...
