Learning path | 3 resources | Published on May 9, 2024

Move your legacy Java application into a container and deploy it to Kubernetes. The Developer Sandbox for Red Hat OpenShift (Developer Sandbox) is a free OpenShift cluster that gives you access to the cutting-edge technologies built on Kubernetes. A quick sign-up gets you a cluster and access to a set of developer tools and services. 

In this learning path created by Don Schenck, you will learn how to create a set of microservices and move this Spring Pet Clinic example application into a container using the Source-to-Image (s2i) feature.
