kubectl get ing gives no address in kubernetes ingress - nginx

Question

Kubernetes is based on ubuntu.When I run the application, the address part of ingress is empty.
service.yaml
apiVersion: v1
kind: Service
metadata:
labels:
app: docker-testmrv
name: docker-testmrv-service
namespace: jenkins
spec:
selector:
app: docker-testmrv
ports:
- protocol: TCP
port: 80
targetPort: 8093
type: LoadBalancer
ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
labels:
app: docker-testmrv
name: docker-testmrv-ingress
namespace: jenkins
spec:
rules:
- host: dockertest.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: docker-testmrv-service
port:
number: 80
ingressClassName: nginx
As you can see in the picture below, the hosts part is empty.I also tried the following in the annotation section, but it didn't work. I've looked and tried other sources as well.
nginx.ingress.kubernetes.io/rewrite-target: /$1
or
ingressclass.kubernetes.io/is-default-class: "true"
or
kubernetes.io/ingressClassName: nginx
kubectl get ing -n jenkins

First we need to ensure nginx enabled and nginx-ingress-controller pod in running status.
Follow below steps to verify :
Enable the NGINX Ingress controller, run the following command:
minikube addons enable ingress
Verify that the NGINX Ingress controller is running
kubectl get pods -n kube-system
As per your YAML, For ingress rule, change the port servicePort from 8093 to 80 the default http port.
Now apply those files and create your pods, service and ingress rule. Wait a few moments, it will take a few moments to get ADDRESS for your ingress rule.

Updated Answer :
Do Nodes have an external ip by default?
If you're using public nodes, each node will have a different public IP and can change every time a node is recreated.
So, Make sure you use the service type as Load balancer to get an external IP on your ingress . NodePort opens any one of the available ports. You can also use NodePort but it might not give you an external IP though instead give a port that will be opened on all the nodes.
Refer this Link to get the difference between cluster IP Node Port and Load balancer different from each other.
Create the service type as Load balancer and add the last line ingressClassName: nginx definition to your ingress yaml. This will work. Refer to this SO
