hello , Could some one please explain two queries

  1. Ingress controller is deployed in pod and has a nodePort service exposed in namespace named “A”
    Suppose a ingress resource is created in another namespace “B” .
    So traffic comes from outside to service in A namespace then to the ingress rule in namespace B and then goes to another service mentioned in that ingress rule to finally reach the webserver-pod.
    Can someone provide some insight on it please?

  2. Also please help me understand Annotations and rewrite-target. I did not understand 216 numbered material from the course.

2. If you need to control the ingress traffic redirection and the return code using a rewrite rule, then you need to use a return directive after the rewrite directive. More info here: https://www.nginx.com/blog/creating-nginx-rewrite-rules|https://www.nginx.com/blog/creating-nginx-rewrite-rules.

  1. Ingress exposes HTTP and HTTPS routes from outside the cluster to services within the cluster. Traffic routing is controlled by rules defined on the Ingress resource.

What about the namespace that the ingress controller is deployed in ? How would it work if the controller and rules are in different namespaces ?
