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
  1. 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
  1. 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

You don’t need to add domain name to Ingress.

Assuming that you are getting a publicly routable IP address from your cloud provider loadbalancer, all you have to do is in your DNS provider add a A record that points that domain name to this IP address.
