The recent release of Eclipse JKube 1.0.0 means that the Fabric8 Maven Plugin is no longer supported. If you are currently using the Fabric8 Maven Plugin, this article provides instructions for migrating to JKube instead. I will also explain the relationship between Eclipse JKube and the Fabric8 Maven Plugin (they’re the same thing) and introduce the highlights of the new Eclipse JKube 1.0.0 release. These migration instructions are for developers working on the Kubernetes and Red Hat OpenShift platforms.
Eclipse JKube is the Fabric8 Maven Plugin
Eclipse JKube and the Fabric8 Maven Plugin are one and the same. Eclipse JKube was first released in 2014 under the name of Fabric8 Maven Plugin. The development team changed the name when we pre-released Eclipse JKube 0.1.0 in December 2019. For more about the name change, see my recent introduction to Eclipse JKube. This article focuses on the migration path to JKube 1.0.0.

Before we had Spring Boot and similar frameworks, a web app container was the main requirement for deploying Java web applications. We now live in the age of microservices, and many Java applications are developed on top of Quarkus, Thorntail, or Spring Boot. But some use cases still require an old-school web application.

Red Hat CodeReady Workspaces 2.2 is now available. For the improvements in this release, we focused on performance and configuration, plus updating CodeReady Workspaces 2.2 to use newer versions of the most popular runtimes and stacks. We also added the ability to allocate only the CPU that you need for IDE plugins, and we introduced a new diagnostic feature that lets you start up a workspace in debug mode.
CodeReady Workspaces 2.2 is available on OpenShift 3.11 and OpenShift 4.3 and higher, including tech-preview support for OpenShift 4.5.
Note: Based on Eclipse Che, CodeReady Workspaces is a Red Hat OpenShift-native developer environment that supports cloud-native development.

The fabric8 Maven plug-in, often abbreviated FMP, can be added to a Maven Java project and takes care of the administrative tasks involved in deploying the application to a Red Hat OpenShift cluster. These tasks include:
- Creating an OpenShift build configuration (BC).
- Coordinating the source-to-image (S2I) process to create a container image from the application’s compiled bytecode.
- Creating and instantiating a deployment configuration (DC) from information in the project.
- Defining and instantiating OpenShift services and routes.
All of the relevant components of this process are well-documented individually. This article pulls together documentation sources to create an overview of how the plug-in works, and the structure of the image it generates—which might make the plug-in easier to use and troubleshoot.

Fabric8 has been available as a Java client for Kubernetes since 2015, and today is one of the most popular client libraries for Kubernetes. (The most popular is client-go, which is the client library for the Go programming language on Kubernetes.) In recent years, fabric8 has evolved from a Java client for the Kubernetes REST API to a full-fledged alternative to the
kubectl command-line tool for Java-based development.
