I’m new to Kubernetes, and am learning how create a cluster and access application through domain name using ingress. I did follow below steps:

1. Created kubernetes cluster attached acr repository.
2. Created helm repo, and made changes

deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: az-kub-demo
  labels:
    app: az-kub-demo
spec:
  replicas: 3
  selector:
    matchLabels:
      app: az-kub-demo
  template:
    metadata:
      labels:
        app: az-kub-demo
    spec:
      containers:
      - name: az-kub-demo
        image: myacr.azurecr.io/az-kub-demo:v1
        ports:
        - containerPort: 8080

---
apiVersion: v1
kind: Service
metadata:
  name: az-kub-demo-service
spec:
  selector:
    app: az-kub-demo
  ports:
    - protocol: TCP
      name: http
      port: 80
      targetPort: 8080      
  type: ClusterIP

3. Created Azure DNS Zone

4. Set Azure DNS Zone name servers to the domain provider (namecheap in my case). It is more than 48hrs now.

5. Updated ingress.yaml as below

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-wildcard-host
spec:
  rules:
  - host: "mydomainname.xyz"
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: az-kub-demo-service
            port:
              number: 80

6. helm install

Added cluster IP to DNS Zone record set

@    A    3600    10.0.121.32
*    A    3600    10.0.121.32

However, application is not accessible with mydomainname.xyz. Not sure if anything is remaining or configured incorrectly.
