selector:
app: webapp
ports:
- protocol: TCP
port: 3000
targetPort: 3000
nodePort: 30100
I ran the commands for each file
kubectl apply -f
i checked the status of the webapp which returned:
app listening on port 3000!
I got the IP address by
minikube ip
and the port was 30100
Why cannot not I access this web app?
I get a site cant be reached error.

If you are on Mac, check your minikube driver. I had to stop, delete minikube, then restart while specifying the hyperkit driver like so.
minikube stop
minikube delete
docker start --vm-driver=hyperkit
The information listed here is pretty useful too.
