I want to add some custom ports in LoadBalancer on my Azure-OpenShift setup(It might be ARO cluster/Azure VM's with OpenShift installer).

  • Do we have option to edit/configure Azure loadbalancer for changing custom ports?
  • If yes, Which is the best way to do. For Example, editing in service manifest or yaml with my custom ports or from AZURE UI etc.
  • Scenario: I have a customer, where I can say please do these steps for changing ports in loadbalancer and you can have your own Ports which has to present for his Azure-OpenShift setup.

OpenShift cluster has loadbalancers for API and Ingress. OpenShift 4.x doesn't manager the API loadbalancer so you can change configuration of the loadbalancer from Azure portal. However, on ARO, you can not change the load balancer on Azure portal because all the resources managed by Azure *1.

For the ingress loadbalancer, that is managed by Load Balancer Service. So, you should modify a yaml file on you cluster as cluster administrator. However, the service is deployed by Ingress Operator. If you removed/changed the service content, Operator may roll back your service as it is. I couldn't find any option on the documentation *2. But you can try to modify the service as you want.
