Red Hat OpenShift 4.6 streamlines developer onboarding in the OpenShift web console, but that’s not all. This article details improvements and new features in the topology view and introduces OpenShift’s new, form-based approach to creating horizontal pod autoscalers and Helm charts. I also touch on application monitoring improvements and the latest updates for Red Hat OpenShift Pipelines, Red Hat OpenShift Serverless, and the Kiali Operator in OpenShift 4.6.
Note: This article presents an overview of what’s new in OpenShift 4.6. See the video at the end of the article for a guide to accessing and using the new features in the OpenShift web console.

In this article, we will define and run a workflow that demonstrates how Apache Camel K interacts with spatial data in the standardized GeoJSON format. While the example is simplified, you can use the same workflow to handle big data and more complex data transformations.

Kubectl, the Kubernetes command-line interface (CLI), has more capabilities than many developers realize. For example, did you know that
kubectl can reach the Kubernetes API while running inside a cluster? You can also use
kubectl to assume different user identities, to select a custom editor to run with the
kubectl edit command, and more.

We’ve added new features in the Red Hat OpenShift 4.6 release to help developers get started faster with the OpenShift web console:
- The default developer perspective is set based on your permissions.
- The developer perspective includes a guided tour.
- Quick starts guide you through common user flows.
- Samples make it easy to deploy new applications on OpenShift.
Keep reading to learn about these new features to improve developer onboarding with the OpenShift web console in OpenShift 4.6.

Podman is an excellent alternative to Docker containers when you need increased security, unique identifier (UID) separation using namespaces, and integration with
systemd. In this article, I use real-world examples to show you how to install Podman, use its basic commands, and transition from the Docker command-line interface (CLI) to Podman. You’ll also see how to run an existing image with Podman and how to set up port forwarding.

KubeVirt is a cloud-native virtual machine management framework based on Kubernetes. KubeVirt orchestrates workloads running on virtual machines in the same way that Kubernetes does for containers. KubeVirt has many features for managing the network, storage, images, and the virtual machine itself. This article focuses on two mechanisms for configuring network and storage requirements: Multus-CNI and CDI DataVolumes. You will learn how to configure these KubeVirt features for use cases that require high performance, security, and scalability.

We are pleased to announce that the new release of the OpenShift Connector extension for Visual Studio Code (VS Code) is now available. The 0.2.0 release offers new features for rapidly developing and deploying code on Kubernetes and Red Hat OpenShift clusters. OpenShift Connector now supports component deployment using devfiles, leveraging odo 2.0 command-line interface under the hood.
With this release, the extension now supports connecting to vanilla Kubernetes clusters and includes a new option for creating OpenShift 4 clusters locally via Red Hat CodeReady Containers (CRC). In this article, we introduce these new features and present the workflow for using CodeReady Containers with OpenShift Connector 0.2.0.
Install OpenShift Connector 0.2.0
- Install the OpenShift Connector plug-in directly from the Visual Studio Code Marketplace.
- Alternatively, select the Extensions view in VS Code by clicking on its square icon in the left-side taskbar. Search for the OpenShift Connector plug-in and click Install.
- Once you have installed the extension, the OpenShift icon will be added to the left-side activity bar and ready for use.

This is the second half of a two-part article about multitenancy with the Jakarta Persistence API (JPA) on WildFly. In Part 1, I showed you how to implement multitenancy using a database. In Part 2, I’ll show you how to implement multitenancy using a schema and the Jakarta Persistence API (JPA) on WildFly. You’ll learn how to implement JPA’s
MultiTenantConnectionProvider interfaces, and how to use JPA’s
persistence.xml file to configure the required classes based on these interfaces.
