The latest update to Red Hat Runtimes features support for Spring Boot 2.2.6, along with the Dekorate project and Spring Reactive. Together, these technologies are a boost for developers building Spring-based applications on the Red Hat OpenShift Container Platform. In this article, I present the highlights of this update.
About Red Hat Runtimes: Red Hat Runtimes provides a set of comprehensive frameworks, runtimes, and programming languages for developers, architects, and IT leaders with cloud-native application development needs. Developers use Red Hat Runtimes to access a variety of application runtimes on the Red Hat OpenShift Container Platform.
Dekorate
Dekorate is an extensive framework that allows developers to abstract the details of editing and avoid hours of tedious work writing XML, YAML, and JSON files. Instead, Dekorate simply generates these manifests at compile time.
Spring Reactive
The latest release of Red Hat Runtimes brings the benefits of Project Reactor and Spring WebFlux to OpenShift and standalone Red Hat Enterprise Linux (RHEL) deployments. In addition to the Spring Boot version update, this release includes a set of Eclipse Vert.x extensions for the Spring Boot runtime. Among the Vert.x extensions is an asynchronous I/O API for reactively handling network communications between application services. These additions extend Spring WebFlux's reactive capabilities while retaining Spring Boot's abstraction and rapid prototyping capabilities.
Red Hat support for Spring Boot
The Red Hat Runtimes team is continuously updating and improving the documentation for building Spring Boot applications on OpenShift and RHEL. Please see the Spring Boot 2.2.6 release notes and the Spring Boot Runtime Guide for more details about Red Hat's support for Spring Boot.
Developer interactive learning scenarios
Red Hat offers a variety of self-paced scenarios to help you learn how to solve real-world problems with Red Hat Runtimes. Each scenario provides a preconfigured Red Hat OpenShift instance that you can access from your browser without any downloads or configuration. You can use the OpenShift instance to experiment with Spring Boot or to learn about other runtimes and technologies. Figure 1 shows a variety of available scenarios.
Red Hat support for Spring Boot
Support for Spring Boot is available to Red Hat customers through a subscription to Red Hat Runtimes. Contact your local Red Hat representative or Red Hat Sales to find out how you can enjoy world-class support from Red Hat and our global partner network.
Note: Moving forward, customers can expect updates to Spring Boot and other runtimes to follow the Red Hat product update and support lifecycle.
What's next for Spring Boot in Red Hat Runtimes
The Red Hat Runtimes Spring Boot team is continually taking feedback from customers and the wider community of open source developers, as well as tracking the changes in upstream Spring Boot releases. The team will continue to update the Red Hat Runtimes support for Spring Boot based on those factors, as well as considering additional modules from Red Hat and the larger Java and Spring communities.
Conclusion
The latest Red Hat Runtimes update was developed by Red Hat's Application Runtimes Product and Engineering team along with the Snowdrop upstream community. These teams collaborated over many hours of development, testing, writing documentation, more testing, and incorporating contributions from the wider Red Hat community of customers, partners, and Spring developers. We hope that it meets or exceeds your expectations!
