Bare-metal cluster are a bit tricky to set-up because you need to create and manage the point of contact to your services. In cloud environment these are available on-demand.

I followed this doc and can assume that your load balancer seems to be working fine as you are able to curl this IP address. However, you are trying to get a response when calling a domain. For this you need some app running inside your cluster, which is exposed to hostname via Ingress component.

I'll take you through steps to achieve that. First, create a Deployment to run a webservice, I'm gonna use simple nginx example:

kind: Deployment
metadata:
  name: nginx-deployment
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 2 
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx
        ports:
        - containerPort: 80 

Second, create a Service of type LoadBalancer to be able to access it externally. You can do that by simply running this command: kubectl expose deployment nginx-deployment --type=LoadBalancer --name=<service_name> If your software load balancer is set up correctly, this should give external IP address to the Deployment you created before.

Last but not least, create Ingress service which will manage external access and name-based virtual hosting. Example:

kind: Ingress
metadata:
  name: <ingress_name>
spec:
  rules:
    - host: <your_domain>
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: <service_name>
                port:
                  number: 80

Now, you should be able to use your domain name as an external access to your cluster.
