I have created a VPC-native cluster on GKE, master authorized networks disabled on it. I think I did all things correctly but I still can't access to the app externally.
Below is my service manifest.
apiVersion: v1
kind: Service
metadata:
annotations:
kompose.cmd: kompose convert
kompose.version: 1.16.0 (0c01309)
creationTimestamp: null
labels:
io.kompose.service: app
name: app
spec:
ports:
- name: '3000'
port: 80
targetPort: 3000
protocol: TCP
nodePort: 30382
selector:
io.kompose.service: app
type: NodePortThe app's container port is 3000 and I checked it is working from logs. I added firewall to open the 30382port in my vpc network too. I still can't access to the node with the specified nodePort. Is there anything I am missing?
kubectl get ep:

NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
app NodePort 10.24.6.14 <none> 80:30382/TCP 6h25m
kubernetes ClusterIP 10.24.0.1 <none> 443/TCP 29hIn Kubernetes, the service is used to communicate with pods.
To expose the pods outside the kubernetes cluster, you will need k8s service of NodePort type.
The NodePort setting applies to the Kubernetes services. By default Kubernetes services are accessible at the ClusterIP which is an internal IP address reachable from inside of the Kubernetes cluster only. The ClusterIP enables the applications running within the pods to access the service. To make the service accessible from outside of the cluster a user can create a service of type NodePort.
Please note that it is needed to have external IP address assigned to one of the nodes in cluster and a Firewall rule that allows ingress traffic to that port. As a result kubeproxy on Kubernetes node (the external IP address is attached to) will proxy that port to the pods selected by the service.
