In the previous post, we took a quick look at a new source-to-image (S2I) builder image designed for building and deploying modern web applications on OpenShift. While the last post was focused on getting your app deployed quickly, this post will look at how to use the S2I image as a “pure” builder image and combine it with an OpenShift chained build.

In this multi-part series, we will take a look at how to deploy modern web applications, like React and Angular apps, to Red Hat OpenShift using a new source-to-image (S2I) builder image. Series overview:
- Part 1 – how to deploy modern web apps using the fewest steps.
- Part 2 – how to combine this new S2I image with a current HTTP server image, like NGINX, using an OpenShift chained build for a more production-ready deployment.
- Part 3 – The last post will show how to run your app’s development server on OpenShift while syncing with your local file system.

Integration testing is still an important step in a CI/CD pipeline even when you are developing container-native applications. Integration tests tend to be very resource-intensive workloads that run for a limited time.
I wanted to explore how integration testing technologies and tools could leverage a container orchestrator (such as Red Hat OpenShift) to run faster and more-dynamic tests, while at the same time using resources more effectively.
In this post, you will learn how to build behavior-driven development (BDD) integration tests using Cucumber, Protractor, and Selenium and how to run them in OpenShift using Zalenium.
The code for the example of this article can be found on GitHub in redhat-cop/container-pipelinesh.

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:

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.

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.

This guide is designed to help you integrate your Red Hat Single Sign-On server with the OpenAPI (OAI)-based ActiveDocs in your 3scale developer portal. Although it has only been implemented with this particular Identity & Access Management solution (IAM), you could in theory make some customizations where necessary to integrate with another OpenID Connect-based solution.

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.
