Hello everybody! In last lab task 7.2.28 there is a meaning "Deploy the httpd server again and test changing traffic from thirdpage over to a new httpd sever using only ingress rule edits." I interpret that as to come up with alternate way to point to a backend. i could not find a much different way except maybe using ExternalName service feature? is that whats hinted?

    Hi @alexanderlvov1,

    It only asks you to deploy a new application and then edit an existing ingress rule to point to the newly deployed app :wink:

    It is straightforward if I create a service for httpd deployment. But without creating a service, I could not get it working. I though maybe backend resource with kind "Deployment" would work, but I could not get it working.

    Hi @sankalpn,

    The Ingress is a layer of network abstraction that sits above the Service layer. Its purpose is to capture traffic from client applications and forward it to Services, which in turn will forward traffic to their Endpoints - that are either un-managed Pods or the Deployment managed Pod replicas.

    Eliminating the Service disconnects the path between the Ingress and the application Pods (unmanaged or managed). Therefore a newly launched application through a Deployment requires a Service as well, before it can be configured with an existing Ingress.
