I’m extremely pleased to announce the release of Red Hat Container Development Kit (CDK) 3.5 and Red Hat Developer Studio 12. Whether you are developing traditional or cloud-based applications and microservices, you can run these tools on your Windows, macOS, or Red Hat Enterprise Linux laptop to streamline development:
- Red Hat Container Development Kit provides a pre-built container development environment to help you develop container-based applications quickly using Red Hat OpenShift and Kubernetes.
- Red Hat Developer Studio (previously named JBoss Developer Studio) provides a desktop IDE with superior support for your entire development lifecycle. It includes a broad set of tooling capabilities and support for multiple programming models and frameworks. Developer Studio provides broad support for working with Red Hat products and technologies including middleware, business automation, and integration, notably Camel and Red Hat Fuse. Developer Studio is based on Eclipse 4.8 (Photon).
A number of Red Hat Enterprise Linux (RHEL) development tools have been updated. These include Rust 1.26.1, Go 1.10.2, Cargo 1.26, and Eclipse 4.8 (Photon).
Our goals are to improve usability of our tools for developers, while adding new features that matter most for users of Red Hat platforms and technologies.
Overview of new features:

For developers working on a Kubernetes-based application environment such as Red Hat OpenShift, there are a number things that need to be considered to fully take advantage of the significant benefits provided by these technologies, including:
- How do I communicate with the orchestration layer to indicate the application is operating correctly and is available to receive traffic?
- What happens if the application detects a system fault, and how does the application relay this to the orchestration layer?
- How can I accurately trace traffic flow between my applications in order to identify potential bottlenecks?
- What tools can I use to easily deploy my updated application as part of my standard toolchain?
- What happens if I introduce a network fault between my services, and how do I test this scenario?
These questions are central to building container-native solutions. At Red Hat, we define container-native as applications that conform to the following key tenets:
- DevOps automation
- Single concern principle
- Service discovery
- High observability
- Lifecycle conformance
- Runtime confinement
- Process disposability
- Image immutability
This may seem like a lot of overhead on top of the core application logic. Red Hat OpenShift Application Runtimes (RHOAR) and Istio provide developers with tools to adhere to these principles with minimal overhead in terms of coding and implementation.
In this blog post, we’re specifically focusing on how RHOAR and Istio combine to provide tools for DevOps automation, lifecycle conformance, high observability, and runtime confinement.

Recently, I wrote a post called Zero to Express on OpenShift in Three Commands, which shows how to get started using Node.js, Express, and OpenShift together as fast as possible using the Node.js s2i (source-to-image) images that were recently released as part of Red Hat OpenShift Application Runtimes (RHOAR).
This post will add to the last one and show how we can start to debug and inspect our running code using the Chrome Developer Tools (DevTools) inspector.

Using Istio with Red Hat OpenShift and Kubernetes makes life with microservices easier. Tucked away inside of Kubernetes pods, using the Istio service mesh, your code can run (mostly) in isolation. Performance, ease-of-changes, tracing, and so on are made available by simply using the Istio sidecar container model. But what if you want your microservice to talk to another service that is outside of your OpenShift/Kubernetes/pods environment?
Enter Istio Egress.
[This is part nine of my ten-part Introduction to Istio Service Mesh series. My previous article was Part 8: Istio Smart Canary Launch: Easing into Production.]

What does this mean for your enterprise? Where does it fit, and how can Red Hat OpenShift Application Runtimes help you use this technology?
Join this session for the answers. We’ll also demonstrate how quickly you can set up non-trivial enterprise-grade Node.js applications on Red Hat OpenShift Container Platform. We’ll explore how to integrate with other open source technologies, such as Istio, and discuss strategies for your Node.js development and deployment pipeline, including canary and blue/green deployment strategies.
Register now and join the live presentation at 12 p.m. EDT, Thursday, April 19th.

At Red Hat Mobile we understand the need for a flexible product that enables our customers to integrate with the tools they need to build their current and future applications. Our position as a leading contributor to the Kubernetes project ensures that the Red Hat OpenShift Container Platform offers this tremendous flexibility to customers and end users.
Red Hat Mobile also supports highly flexible integrations to a range of 3rd party services and products. In this article, we’ll demonstrate how Red Hat Mobile v4 and OpenShift v3 enable customers to rapidly deploy and secure their mobile applications by integrating with a third party product provided by Intercede. We’ll be using Intercede’s RapID product to enable two-way TLS (often referred to as Client Certificate Authentication or CCA) for our mobile application.

Today Red Hat is making Node.js generally available to Red Hat customers through a subscription to Red Hat OpenShift Application Runtimes (RHOAR). RHOAR provides application developers with a variety of application runtimes running on the OpenShift Container Platform.

Over the past few weeks I have been learning and enhancing my skills around the new buzz word “serverless” and trying to understand what this buzz is all about. As an ardent open-source developer, I was looking for a platform where I can develop and deploy the serverless functions, which is when I stumbled upon Apache OpenWhisk.
In this blog I will demonstrate how to build a simple nodejs function that can do reverse geocoding using Google Maps API, and how to deploy the functions on to Apache OpenWhisk.

In this Blog post entry I will try to cover, how to use Red Hat Mobile Application Platform with private npm modules from registry.npmjs.org.
