I'm struggling with kubernates configurations. What I want to get it's just to reach a deployment within the cluster. The cluster is on my dedicated server and I'm deploying it by using Kubeadm.

My nodes:

$ kubectl get nodes
NAME          STATUS   ROLES    AGE   VERSION
k8s-master    Ready    master   9d    v1.19.3
k8s-worker1   Ready    <none>   9d    v1.19.3

I've a deployment running (nginx basic example)

$ kubectl get deployment
NAME               READY   UP-TO-DATE   AVAILABLE   AGE
nginx-deployment   2/2     2            2           29m

I've created a service

$ kubectl get svc
NAME         TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1       <none>        443/TCP   9d
my-service   ClusterIP   10.106.109.94   <none>        80/TCP    20m

The YAML file for my service is the following:

apiVersion: v1
kind: Service
metadata:
  name: my-service
spec:
  selector:
    app: nginx-deployment
  ports:
    - protocol: TCP
      port: 80

Now I should expect, if I run curl 10.106.109.94:80 on my k8s-master to get the http answer.. but what I got is:

curl: (7) Failed to connect to 10.106.109.94 port 80: Connection refused

I've tried with NodePort as well and with targetPort and nodePort but the result is the same.
