In part three of this series, we have seen how to deploy our Quarkus/Camel-based microservices in Minikube, which is one of the most commonly used Kubernetes local implementations. While such a local Kubernetes implementation is very practical for testing purposes, its single-node feature doesn't satisfy real production environment requirements. Hence, in order to check our microservices behavior in a production-like environment, we need a multi-node Kubernetes implementation. And one of the most common is OpenShift.
What Is OpenShift?
OpenShift is an open-source, enterprise-grade platform for container application development, deployment, and management based on Kubernetes. Developed by Red Hat as a component layer on top of a Kubernetes cluster, it comes both as a commercial product and a free platform or both as on-premise and cloud infrastructure. The figure below depicts this architecture.
