I have two ingress routes created as below,
kubesphere-console
tekton-pipelines

My manifest files are as like below.

cat ingress-tekton-dashboard.yaml 
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: tekton-dashboard
  annotations:
    ingress.kubernetes.io/ssl-redirect: "false"
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
spec:
  rules:
  - http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
           name: tekton-dashboard
           port:
             number: 9097
    #host: *
...
cat ../kubesphere/ingress-route-kubesphere.yaml 
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: kubesphere-console
  annotations:
    kubesphere.io/creator: admin
spec:
  ingressClassName: nginx
  rules:
  - http:
      paths:
      - path: /
        pathType: ImplementationSpecific
        backend:
          service:
            name: ks-console
            port:
              number: 80
---

My ingress are as below:

k get ing -nkubesphere-system
NAME                 CLASS   HOSTS   ADDRESS        PORTS   AGE
kubesphere-console   nginx   *       20.92.133.79   80      28h
ameya@Azure:~/tekton$ k get ing -ntekton-pipelines
NAME               CLASS    HOSTS   ADDRESS   PORTS   AGE
tekton-dashboard   <none>   *                 80      2m32s

My service for tekton dashboard is like below:

k get svc -n tekton-pipelines
NAME                          TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)                              AGE
tekton-dashboard              ClusterIP   10.0.202.127   <none>        9097/TCP                             2d3h
tekton-pipelines-controller   ClusterIP   10.0.53.46     <none>        9090/TCP,8008/TCP,8080/TCP           2d6h
tekton-pipelines-webhook      ClusterIP   10.0.222.121   <none>        9090/TCP,8008/TCP,443/TCP,8080/TCP   2d6h

I need some guidance to understand why tekton-dashboard is not getting IP?
