Monitor Node.js applications on Red Hat OpenShift with Prometheus

A great thing about Node.js is how well it performs inside a container. With the shift to containerized deployments and environments comes extra complexity. One such complexity is observing what’s going on within your application and its resources, and when resource use is outside of the expected norms.

Using Dekorate to generate Kubernetes manifests for Java applications

Using Dekorate to generate Kubernetes manifests for Java applications

To deploy an application on Kubernetes or Red Hat OpenShift, you first need to create objects to allow the platform to install an application from a container image. Then, you need to launch the application using a pod and expose it as a service with a static IP address. Doing all of that can be tedious, but there are ways to simplify the process.

No more Java in vscode-xml 0.15.0!

Among other improvements and bug fixes in the vscode-xml extension 0.15.0 release, you can now run the extension without needing Java.

Ansible organizes these tasks in playbook files, which run on one or more remote target hosts. Inventory files maintain lists of these hosts and are formatted as YAML or INI documents. For example, a simple inventory file in INI format follows:

Deploying Node.js applications to Kubernetes with Nodeshift and Minikube

Deploying Node.js applications to Kubernetes with Nodeshift and Minikube

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.
