Test

List the resources in app2

$ kubectl get po,svc -n app2
NAME READY STATUS RESTARTS AGE
pod/nginx 1/1 Running 0 8s

NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/nginx NodePort 10.106.164.238 <none> 80:30000/TCP 8s

From a worker node, try to reach the nginx Pod

$ curl localhost:30000
curl: (7) Failed to connect to localhost port 30000: Connection refused

Check the service

kubectl describe svc nginx -n app2
Name: nginx
Namespace: app2
Labels: <none>
Annotations: <none>
Selector: app=nginx
Type: NodePort
IP Family Policy: SingleStack
IP Families: IPv4
IP: 10.106.164.238
IPs: 10.106.164.238
Port: <unset> 80/TCP
TargetPort: 80/TCP
NodePort: <unset> 30000/TCP
Endpoints: <none>
Session Affinity: None
External Traffic Policy: Cluster
Events: <none>

The list of Endpoints is empty, that is surely a problem. The Service’s selector is app: nginx, let’s see the content of the Pod’s labels.
