Practical Cloud-Native Java Development with MicroProfile

By: Emily Jiang, Andrew McCright, John Alcorn, David Chan, Alasdair Nottingham

Overview of this book

In this cloud-native era, most applications are deployed in a cloud environment that is public, private, or a combination of both. To ensure that your application performs well in the cloud, you need to build an application that is cloud native. MicroProfile is one of the most popular frameworks for building cloud-native applications, and fits well with Kubernetes. As an open standard technology, MicroProfile helps improve application portability across all of MicroProfile's implementations. Practical Cloud-Native Java Development with MicroProfile is a comprehensive guide that helps you explore the advanced features and use cases of a variety of Jakarta and MicroProfile specifications. You'll start by learning how to develop a real-world stock trader application, and then move on to enhancing the application and adding day-2 operation considerations. You'll gradually advance to packaging and deploying the application. The book demonstrates the complete process of development through to deployment and concludes by showing you how to monitor the application's performance in the cloud. By the end of this book, you will master MicroProfile's latest features and be able to build fast and efficient cloud-native applications.

Deploying the application via the CLI

Sometimes you need to do things via an approach other than using a graphical user interface. Maybe you just prefer using a CLI. Or, perhaps you want to automate such work as steps in a Continuous Integration / Continuous Deployment (CI / CD) pipeline. Or, maybe you are using a Kubernetes distribution other than Red Hat OpenShift Container Platform (OCP), such as from one of the hyperscalers, such as Amazon Web Services (AWS) or Microsoft Azure. To deploy the application without the benefit of the OpenShift console, follow these steps:

  1. The first thing you'll need to do is to make sure that the Operator Lifecycle Manager (OLM) feature is installed in your Kubernetes cluster. This can be done via the operator-sdk (which you can install on your Mac via brew install operator-sdk) by following the instructions at


    operator-sdk is used to produce an operator such as the one for the...
