After nine months of incubation with the Eclipse Foundation, Eclipse JKube 1.0.0 is finally here. This release marks the final deprecation of the great Fabric8 Maven Plugin (FMP) project. JKube is a complete replacement of FMP and includes all of the major features. Projects relying on FMP to create Apache Maven Java containers should migrate to Eclipse JKube to take full advantage of the new features, bug fixes, and upstream project maintenance described in this article.
JKube is a collection of plugins plus a standalone Java library that fit into your Maven project. If you have a Java project that needs to get deployed into Kubernetes or Red Hat OpenShift, this is the right tool for you. JKube takes care of everything related to the cluster deployment while you, as a developer, get to concentrate on implementing your application without worrying about where it needs to be deployed.

How do YOU get your Java apps running in a cloud?
First you grab a cloud from the sky by, for example, (1) Getting started with a free account on Red Hat OpenShift Online, or (2) locally on your laptop using Red Hat Container Development Kit (CDK) or upstream Minishift on Windows, macOS, and Linux, or (3) using
oc cluster up (only on Linux), or (4) by obtaining a login from someone running Red Hat OpenShift on a public or on-premises cloud. Then, you download the oc CLI client tool probably for Windows (and put it on your PATH). Then you select the Copy Login Command from the menu in the upper right corner under your name in the OpenShift Console’s UI, and you use, for example, the
oc status command.
Great—now you just need to containerize your Java app. You could, of course, start to write your own Dockerfile, pick an appropriate container base image (and discuss Red Hat Enterprise Linux versus CentOS versus Fedora versus Ubuntu versus Debian versus Alpine with your co-workers; and, especially if you’re in an enterprise environment, figure out how to have that supported in production), figure out appropriate JVM startup parameters for a container, add monitoring, and so.
But perhaps what you really wanted to do today is…well, just get your Java app running in a cloud!
Read on to find an easier way.
