503 Service Temporarily Unavailable using Kubernetes I am having some issue with creating ingress for a nginx service that I deployed in a kubernetes cluster. I am able to open the web page using port forwarding, so I think the service should work.The issue might be with configuring the ingress.I checked for selector, different ports, but still could not find where goes wrong. Anyone could help ? Thank you in advance.

i'm guessing the problem is that the name of the service port is not configured, and in the ingress you specified the http name and it can not find it.
name your port http , or give the port that you want to use (80) to the servicePort in the ingress file
