It extends Kubernetes with additional features for easier management, security, and developer experience. Steps To Reproduce Expose a route to a service with multiple port Just a note here, that might save some time to somebody else: When the route is created automatically by an ingress, it is still not possible to have the same route/ingress serving both HTTP & HTTPS, without redirect (as per 09/2024). When a web application is made visible outside of the OpenShift cluster a route is created. However, the most common way to expose a service outside of your cluster is by using another Kubernetes resource called Ingress. 1.
