How to redirect the port in ingress?

[ukreddy-erwin]

Hello Sir,

I have recently registered to your udemy course.
In that ingress section, you added routes to multiple application but all having container port as 80 only.
With Ingress, our application is using port 18170.
But with ingress, even if I keep servicePort as 18170, it is not working.

Can you create a video on that and to your course.

Like, adding routes to multiple apps with different ports for their service.
