Kubernetes's LoadBalancer yaml not working even though CLI `expose` function works - kubernetes

Question

This is my Service and Deployment yaml that I am running on minikube:
apiVersion: apps/v1
kind: Deployment
metadata:
name: node-hello-world
labels:
app: node-hello-world
spec:
replicas: 1
selector:
matchLabels:
app: node-hello-world
template:
metadata:
labels:
app: node-hello-world
spec:
containers:
- name: node-hello-world
image: node-hello-world:latest
imagePullPolicy: Never
ports:
- containerPort: 8080
---
apiVersion: v1
kind: Service
metadata:
name: node-hello-world-load-balancer
spec:
type: LoadBalancer
ports:
- protocol: TCP
port: 9000
targetPort: 8080
nodePort: 30002
selector:
name: node-hello-world
Results:
$ minikube service node-hello-world-load-balancer --url
http://192.168.99.101:30002
$ curl http://192.168.99.101:30002
curl: (7) Failed to connect to 192.168.99.101 port 30002: Connection refused
However, running the following CLI worked:
$ kubectl expose deployment node-hello-world --type=LoadBalancer
$ minikube service node-hello-world --url
http://192.168.99.101:30130
$ curl http://192.168.99.101:30130
Hello World!
What am I doing wrong with my LoadBalancer yaml config?

Answer 1

you have configured wrong the service selector
selector:
name: node-hello-world
it should be:
selector:
app: node-hello-world
https://kubernetes.io/docs/tutorials/kubernetes-basics/expose/expose-intro/
you can debug this by describing the service, and seeing that the endpoint list is empty, so there are no pods mapped to your endpoint's service list
kubectl describe svc node-hello-world-load-balancer | grep -i endpoints
Endpoints: <none>
