Source to Image Builder for Open Liberty Apps on OpenShift

Posted on June 25, 2019June 25, 2019 by Niklas Heidloff

OKD, the open source upstream Kubernetes distribution embedded in OpenShift, provides several ways to make deployments of applications to Kubernetes for developers easy. I've open sourced a project that demonstrates how to deploy local Open Liberty applications via two simple commands 'oc new-app' and 'oc start-build'. (more…)

Free and self paced workshop: How to develop microservices with Java

Posted on June 24, 2019June 25, 2019 by Niklas Heidloff

Over the last weeks I've worked on an example application that demonstrates how to develop your first cloud-native applications with Java/Jakarta EE, Eclipse MicroProfile, Kubernetes and Istio. Based on this example my colleague Thomas Südbröcker wrote a workshop which explains how to implement resilient microservices, how to expose and consume REST APIs, how to do traffic management and more.

How to build and run a Hello World Java Microservice

Posted on June 17, 2019June 25, 2019 by Niklas Heidloff

The repo cloud-native-starter contains an end-to-end sample application that demonstrates how to develop your first cloud-native applications. Two of the microservices have been developed with Java EE and MicroProfile. To simplify the creation of new Java EE microservices, I've added another very simple service that can be used as template for new services. (more…)

Persistence for Java Microservices in Kubernetes via JPA

Posted on May 21, 2019May 23, 2019 by Niklas Heidloff

Over the last weeks I've worked on an example application that demonstrates how Java EE developers can get started with microservices. The application is a full end-to-end sample which includes a web application, business logic, authentication and now also persistence. It runs on Kubernetes and Istio and there are scripts to easily deploy it. (more…)

Authorization in Microservices with MicroProfile

Posted on May 20, 2019May 23, 2019 by Niklas Heidloff

I've been working on an example that demonstrates how to get started with cloud-native applications as a Java developer. The example is supposed to be a full end-to-end sample application which includes the topis authentication and authorization, since that functionality is required by most applications. This article describes how to check authorization in microservices implemented with Java EE and Eclipse MicroProfile. (more…)
