Eclipse JKube

Cloud-Native Java Applications without a hassle

Eclipse JKube is a library and a collection of plugins used for building container images using Docker, JIB or S2I build strategies (more to come).

Eclipse JKube generates Kubernetes and OpenShift resource manifests too and applies/deploys them into the cluster.

JKube provides additional developer tools to ease Java development in the cloud.


Quarkus
Introduction Quarkus provides its very own templating engine, Qute. In this post, I will show you how to use it to render Markdown from different sources using flexmark-java. Besides showcasing Qute, another reason for this post is to show complex assembly configurations to build container images using Eclipse JKube. I designed the project to be run in Kubernetes, so some of the features won’t be available if the application is run locally. The application renders a template with markdown fragments loaded from different locations, highlighting how these fragments can be assembled into the container image using different techniques and ultimately […]

Camel
Introduction Eclipse JKube 1.0.0 GA will be released on September 9, 2020. As I mentioned in previous posts, JKube is the successor of the deprecated Fabric8 Maven Plugin (FMP), and as such, our main goal right now is to migrate the current user-base to the new project. Aligned with this strategy, we started to create Pull Requests on those repositories that are currently using FMP in order to replace the deprecated dependency. In this article, I’ll describe how to run the updated Apache Camel example (now using JKube) for Cassandra running on Kubernetes, and its expected behavior. This blog post […]

Quarkus
Introduction During the past few months, my team and I have been working very hard to release Eclipse JKube. JKube is the successor of the deprecated Fabric8 Maven Plugin, and as such, our main goal right now is to migrate the current user-base to the new project. GitHub provides some fancy stats and metrics, including information about the project’s dependency graph. This information is really valuable since we get to know which projects (within GitHub) depend on ours. So for our user-base migration use case, this information is spot on. Unfortunately, the GitHub developers API offers information about dependencies, but […]

YAKC - Yet Another Kubernetes Client
Introduction This example shows how you can access the Kubernetes cluster’s REST API from inside a Pod using YAKC (Yet Another Kubernetes Client), Eclipse JKube and Spring Boot. The first part of the tutorial shows how to create a very simple Spring Boot application with the required YAKC Kubernetes Client dependency (see introductory post for YAKC). The second part describes how to quickly deploy the application into a Kubernetes cluster and how to perform requests to the Pod’s REST endpoints to retrieve information from the cluster. Example application The first step will be to create an example Spring Boot Maven […]
