This repository contains the OpenShift routers for NGINX, HAProxy, and F5. They read Route objects out of the OpenShift API and allow ingress to services. HAProxy is currently the reference implementation. See the details in each router image.

These images are managed by the cluster-ingress-operator in an OpenShift 4.0+ cluster.

The template router code (openshift-router) is generic and creates config files on disk based on the state of the cluster. The process launches proxies as children and triggers reloads as necessary after new config has been written. The standard logic for handling conflicting routes, supporting wildcards, reporting status back to the Route object, and metrics live in the standard process.

The OpenShift router can be run against a vanilla Kubernetes cluster, although some of the security protections present in the API are not possible with CRDs.

To deploy, clone this repository and then run:

$ kubectl create -f deploy/

You will then be able to create a Route that points to a service on your cluster and the router pod will forward your traffic from port 80 to your service endpoints. You can run the example like:

$ kubectl create -f example/

And access the router via the node it is located on. If you're running locally on minikube or another solution, just run:

$ curl http://localhost -H "Host: example.local"

to see your route and:

$ kubectl get routes

to see details of your routes.
