Not able to find out the java application url deployed through helm on a local kubernetes cluster-CodePudding

Have deployed an application successfully using helm chart but I am unable to understand which url should I use to access it ..Here is the Nodeport service created by Helm for this web app :

kubectl get svc

You have deployed an application that is exposed using a Service of kind NodePort.

That means that all nodes of the cluster expose the application on the same port - the port number is coordinated.

So you need the ip of one of the nodes to access the cluster. You can use kubectl get nodes -o wide to get the nodes and IP addresses. If it is a local cluster it will be shown as INTERNAL IP.

$ kubectl get nodes -o wide
NAME       STATUS   ROLES                  AGE    VERSION   INTERNAL-IP    EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION      CONTAINER-RUNTIME
minikube   Ready    control-plane,master   155m   v1.23.3   192.168.49.2   <none>        Ubuntu 20.04.2 LTS   5.15.0-37-generic   docker://20.10.12

Use one of the IPs together with your NodePort which is 31384. In my example it would be: http://192.168.49.2:31384

So,a s I am only learning this thing using a self paced course , I was able to follow Thomas's suggestion https://chat.stackoverflow.com/rooms/246100/discussion-between-rohit-and-thomas ) and access the application inside kubernetes shell , does the job for now . Thank you Thomas :)
