As discussed in below thread, we should improve quickstart to not print a simple message, which seems to cause repeated restarts.
Rather we can have it as a web application using Spring Boot/Quarkus and display a hello world HTML web page.

After following the Readme steps for a quick start of the Hello-World app, I am facing a few issues.
What works:
The build is successful with mvn clean install k8s:build k8s:resource k8s:apply
minikube start command runs minikube container in my docker desktop and opens five ports
⚠️ I have shared minikube's docker daemon environment with my shell
What does not work:
kubectl get pods shows:
NAME READY STATUS RESTARTS AGE
helloworld-588b59fd98-69prl 0/1 CrashLoopBackOff 8 (2m30s ago) 18m
helloworld-85595f97f7-2x2pg 0/1 CrashLoopBackOff 8 (2m24s ago) 3h57m
kubectl describe pod outputs:

The last line above shows container is present but the status is CrashLoopBackOff instead of Completed. What could I be missing?

Java 21 provides an extremely easy way to create webserver with a 2 or 3 liner code.
Just look for that online. We just need an endpoint that prints a message.
