When you want to get traffic into your OpenShift cluster, Routes are just awesome. But every now and then, using Ingress instead might provide some benefits. Here are a few tricks how you can have the best of both worlds.
OpenShift Routes predate the Ingress resource , they have been part of OpenShift 3.0! Routes are just awesome. Instead of fiddling with services and load balancers, you have a single load balancer for bringing in multiple HTTP or TLS based services. The idea is pretty simply, instead of patching through multiple services, you patch through only one: HAproxy. Which then gets configured to direct traffic to the different services inside the cluster.
That way, it is possible to configure a single application domain, issue a wildcard certificate for that domain. So you can create route objects, auto-assign a DNS name and have it secured with TLS automatically. Without needing to issue or refresh certificates individually or maintain DNS entries yourself. It is absolutely simple.
