If you are not familiar with the oc command, refer to OpenShift - Getting Started with the oc command.

• Using an OpenShift route (this is the most common)
• Using an ingress route
• Using a load balancer service
• Assign an external IP address to a service

An OpenShift route or an Ingress route will provide a URL such as http://my-route-my-project.apps.openshift.example.com:8080 which is used to route a request onto a service, which is then routed onto a pod, and then to the container in the pod, and finally to the application running in the container.

Like this.

The oc get ingress command can then be used the list the Ingress routes in the project/namespace.

~]$ oc get ingress
NAME               CLASS    HOSTS                   ADDRESS   PORTS   AGE
my-ingress-route   <none>   openshift.example.com             80      4s

The oc describe ingress command can be used to show more details about the ingress route.

~]$ oc describe ingress my-ingress-route
Name:             my-ingress-route
Namespace:        my-project
Address:          
Default backend:  default-http-backend:80 (<error: endpoints "default-http-backend" not found>)
Rules:
  Host                    Path  Backends
  ----                    ----  --------
  openshift.example.com  
                          /my-endpoint  my-service:8080 (10.131.4.14:8080)
Annotations:              <none>
Events:                   <none>

Or, the oc get ingress command with the --output json or --output yaml option can be used.

~]$ oc get ingress my-ingress-route --output yaml
