Somehow, I am trying to start a kubernetes project on Google Compute (not GKE). After all installation (read docker-ce, kubelet, kubeadm) I create a Service and a Deployment inside as follows :
apiVersion : v1
kind : Service
metadata:
name: client-node-port
spec:
type: NodePort
ports:
- port: 90
targetPort: 80
nodePort: 31515
selector:
component: webIt was working until I change the targetPort inside service to any port beside 80 (along with the Deployment containerPort).
I already tried enabling the port on the instance firewall-cmd --permanent --add-port=(any port beside 80)/tcp
Beside that I also already enable the firewall rule in google Google Firewall Setting
Is there anything that I missed ? Why I can only access the NodePort when nodePort setting in the service is 80 ?
Thanks
PS : If it is relevant, I am using flannel network
May I know why you are trying to change targetPort ?
TargetPortis the port on the POD where the service is running.
Nodeportis the port on which the service can be accessed from external users by nodeip:nodeport.
Port: the same as Nodeport but can be used by cluster users using clusterip:port.
Again, in your case port 80 represents the service is actually running on port 80.
You should change targetPortin case you will set the service in the pod that is running on a different port.
Review this question for more details.
