how to setup separate DNS endpoints for all different Apps running in Kubernetes Cluster???(AWS/GCP/AZURE)

For example:

app1 service running on Nodeport: 30001

app2 service running on Nodeport: 30002

app1 endpoint DNS should be www.app1.com

app2 endpoint DNS should be www.app2.com

You can format your yaml by highlighting it and pressing Ctrl-Shift-C, it will make your output easier to read.

As far as I know there is no way to have DNS route to a port directly. generally to have multiple endpoints for multiple apps in a single cluster an ingress resource is used. This will receive the traffic and the route it to your pods through their services.

for a more detailed explenation check: Ingress - Kubernetes

What you want is SRV records in DNS, but mostly nobody uses them for this. Sorry.
