In a previous article, I showed how easy it was to deploy a Node.js application during development to Red Hat OpenShift using the Nodeshift command-line interface (CLI). In this article, we will take a look at using Nodeshift to deploy Node.js applications to vanilla Kubernetes—specifically, with Minikube.

Tekton is a powerful, Kubernetes-native framework for creating continuous integration and delivery (CI/CD) systems. In this article, we’ll use real-world examples to show you how to install Tekton, create Tasks, and eventually create our own pipeline.

Kubernetes Operators reduce the work of human operators or site reliability engineers. Rather than a half-baked definition, I refer you to this original definition from the creators of the Kubernetes Operator Framework: Operators are Kubernetes applications.

The Eclipse Che 7.6.0 release provides a new stack for Apache Camel K integration development. This release is the first iteration to give a preview of what is possible. If you like what you see, shout it out, and more will surely come.
This article details how to test this release on a local instance deployed on minikube. The difference with a hosted instance is that we avoid the prerequisites involving Camel K installation in the cluster and specific rights for the user.

Minikube has a feature called add-ons, which help in adding extra components and features to Minikube’s Kubernetes cluster.
The registry add-on will deploy an internal registry, which can then be used to push and pull Linux container images. But at times, we might wish to mimic push and pull to different registries (i.e., using aliases for container registry). In this article, I will walk you through the steps required to achieve the same.

Kubernetes has grown to be a de facto development platform for building cloud-native applications. As developers, we want to be productive from the word go, or, shall we say, from the word code. But to be productive, we must be armed with the right set of tools. In this article, I will take a look at three important tools that should become part of your Kubernetes tool chest, or armory.

The tutorial Spring Boot and OAuth2 showed how to enable OAuth2 with Spring Boot with Facebook as AuthProvider; this blog is the extension of showing how to use KeyCloak as AuthProvider instead of Facebook. I intend to keep this example as close to the original Spring Boot and OAuth2 and will explain the changes to the configuration to make the same application work with KeyCloak. The source code for the examples are available in the github repositories listed below.
