Red Hat OpenShift 4.15, based on Kubernetes 1.28 and CRI-O 1.28, is now generally available. This article highlights notable updates in this release for developers with OpenShift.

Pipelines, Developer Hub, and more

The Developer Perspective in the OpenShift console includes four new capabilities:

The PipelineRun Details page in the Developer or Administrator perspective of the web console provides an enhanced visual representation of PipelineRuns within a Project.

Discover Red Hat Developer Hub in the web console with new quick starts that provide step-by-step instructions to learn how to install and use Developer Hub (Figure 1). Red Hat Developer Hub 1.0, based on the Backstage project, provides software templates and plug-ins for OpenShift deployments, access to pipeline runs, viewing clusters from OpenShift Cluster Manager, and more.

Builds for OpenShift Container Platform 1.0, an extensible build framework based on the Shipwright project, lets you build container images in the web console.

Podman Desktop 1.7’s enhanced onboarding experience makes it easier to set up your local environment. Use the Red Hat OpenShift Local extension to create local clusters. Use the UI to manage Pods, Services, Deployments, and Routes.

The OpenShift Toolkit IDE extension by Red Hat for Visual Studio Code and IntelliJ now has a UI for Helm charts with Helm repo management. It allows performing Import From Git and deploying applications (from AI applications to Quarkus applications) directly from OpenShift (Red Hat OpenShift Service on AWS, Microsoft Azure Red Hat OpenShift, Red Hat OpenShift Local), and it integrates OpenShift Serverless Functions with OpenShift Toolkit for VS Code for OpenShift Serverless 1.31 and Function CLI 1.13.

OpenShift Pipelines 1.14 based on Tekton 0.56

OpenShift Pipelines is a cloud-native continuous integration and continuous delivery (CI/CD) solution based on Kubernetes that automates deployments across multiple platforms by removing hidden implementation details.

Release 1.14 introduces Tekton Results in Technology Preview, which provides support for external databases and storage as well as a new API for detailed log summaries with various filters. Pipelines As Code adds multiple GitHub Apps support and remote pipeline capabilities in PAC resolver which makes pipeline management more seamless.

The Secrets Store CSI driver and Tekton integration are now validated and make Red Hat Enterprise Linux (RHEL) entitlements available in Buildah pods. Tekton Results are now accessible in the console and as a dynamic plug-in for a CI-centric dashboard. See the OpenShift Pipelines release notes to read about other improvements.

OpenShift GitOps 1.12 based on Argo CD 2.10 coming in March

Red Hat OpenShift GitOps allows administrators to consistently configure and deploy Kubernetes infrastructure and applications across clusters and development life cycles. Release 1.11 released in December introduces dynamic shard rebalancing in Technology Preview. Dynamic shard rebalancing makes it easier to manage replicas of applications and distribute cluster resources per shard. In addition, dynamic rebalancing lets you set maximum and minimum shards while the round-robin algorithm manages the process.

Gitlab SCM provider now supports self-signed certs. Release 1.12 adds Technology Preview support for the upstream Argo CD command-line interface (CLI), a rollouts traffic management plugin for OpenShift Routes, and Technology Preview for OpenShift GitOps for MicroShift which only includes the core Argo CD components for a smaller footprint version of GitOps. Additionally, Notifications goes GA. More information can be found in the OpenShift GitOps 1.11 release notes.

Figure 2: OpenShift Serverless Functions in the Developer Console.

OpenShift Serverless provides autoscaling and networking for containerized microservices and functions. Serverless functions increases developer velocity by providing templates to jump-start both application and container creation and now supports persistent volume claims (PVCs) which provide permanent data storage and a more refined Developer Console experience.

You can create OpenShift Serverless functions through the developer console using the OpenShift Container Platform Pipeline (Figure 2). OpenShift Serverless multi-tenancy with Service Mesh is now available as a Technology Preview (TP) feature for both Serving and Eventing. For edge use cases, Serverless is now supported with single node OpenShift. To learn more, please see the OpenShift Serverless 1.32 release notes

OpenShift Service Mesh 2.5 based on Istio 1.18 and Kiali 1.73

Red Hat OpenShift Service Mesh creates a central point of control in an application. The latest release adds General Availability support for Arm clusters, more options for observability integrations with the addition of Zipkin, OpenTelemetry, and envoyOtelAls extension providers, and GA of OpenShift Service Mesh Console plug-in. IPv4/IPv6 dual-stack support and the Kiali Backstage plug-in for Red Hat Developer Hub are both available in Developer Preview. The updated Developer Preview of the Service Mesh 3 Kubernetes Operator (or the Sail Operator) is available. More information can be found in the OpenShift Service Mesh 2.50 release notes.

Harness application performance with observability

Red Hat build of OpenTelemetry, based on OpenTelemetry, unifies, standardizes, and delivers vendor-neutral telemetry data collection for cloud-native software. The Red Hat build of OpenTelemetry 3.1 (based on OpenTelemetry 0.93.0) adds support for the target allocator in the OpenTelemetry Collector, which is an optional component of the OpenTelemetry operator that shards Prometheus receiver scrape targets across the deployed fleet of OpenTelemetry Collector instances and provides integration with the Prometheus PodMonitor and ServiceMonitor custom resources. 

Power Monitoring for Red Hat OpenShift 0.1, based on Kepler is in Technology Preview, is integrated into the Console and shows the total energy consumed in the clusters during the last 24 hours, including the CPU architecture, number of monitored nodes, source for the power metrics and a breakdown of the top power consuming namespaces. With OpenShift Logging 5.9, log metrics are displayed in the Log UI in the Console and can be searched across namespaces.

Modernize cloud-native applications

Red Hat's migration toolkit for applications 7.0 supports multiple languages, adds new rules syntax, automates classification, and provides dynamic reports. Container images for OpenShift are available with Node.js 20. The Java 21 builder and runtime container images for OpenShift are available. Quarkus 3.8 (coming soon) will add Redis 7.2 support, Java 21 support, Arm native support, and OpenSearch Dev services. Spring Boot 3.1.x and 3.2.x have tested and verified runtimes on OpenShift.
