How can I add my external domain “uat.test.com ” to my kubernetes cluster by using nginx-ingress?

Question

I am new for kubernetes and Have an issue for ingress nginx for external domain from godaddy. it is called " https://uat.test.com ".I created some yaml for nginx-ingress but I couldn't do that. How can I add "uat.test.com " to my kubernetes cluster by using nginx-ingress?

Below; They are my steps for my funny and stressful advantures.

1. Create group and namespace:

az group create --name aks-group --location eastus2

az aks create --resource-group aks-group --name aks-cluster --node-count 3 --generate-ssh-keys -s Standard_B2ms --disable-rbac

kubectl create namespace ingress-basic

2. Credentials:

az aks get-credentials -g aks-group -n aks-cluster

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.43.0/deploy/static/provider/cloud/deploy.yaml
 
az aks get-credentials -g aks-group -n aks-cluster

kubectl --namespace ingress-basic get services -o wide -w nginx-ingress-ingress-nginx-controller

3. install ingress-nginx:

helm install ingress-nginx ingress-nginx/ingress-nginx
   
helm repo update
    
helm install nginx-ingress ingress-nginx/ingress-nginx --namespace ingress-basic --set controller.replicaCount=2
     
kubectl --namespace ingress-basic get services -o wide -w nginx-ingress-ingress-nginx-control

somewhere you need to bind the public IP address of your clusters ingress controller to your DNS name. That does not happen in AKS (or anywhere in your k8s configs). You need to do that with your DNS provider.
