I want to start out by saying I do not know the exact architecture of the servers involved.. All I know is that they are Ubuntu machines on the cloud.

I have set up a 1 master/1 worker k8s cluster using two servers.

kubectl cluster-info gives me:

Kubernetes master is running at https://10.62.194.4:6443
KubeDNS is running at https://10.62.194.4:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

I have created a simple deployment as such:

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  labels:
    run: nginx
  name: nginx-deploy
spec:
  replicas: 2
  selector:
    matchLabels:
      run: nginx
  template:
    metadata:
      labels:
        run: nginx
    spec:
      containers:
      - image: nginx
        name: nginx
        ports:
        - containerPort: 80

Which spins up an nginx pod exposed on container port 80.

I have exposed this deployment using:

kubectl expose deployment nginx-deploy --type NodePort

When I run kubectl get svc, I get:

nginx-deploy   NodePort    10.99.103.239   <none>        80:30682/TCP   29m

kubectl get pods -o wide gives me:

nginx-deploy-7c45b84548-ckqzb   1/1     Running   0          33m   192.168.1.5   myserver1   <none>           <none>
nginx-deploy-7c45b84548-vl4kh   1/1     Running   0          33m   192.168.1.4   myserver1   <none>           <none>

Since I exposed the deployment using NodePort, I was under the impression I can access the deployment using < Node IP > : < Node Port >

The Node IP of the worker node is 10.62.194.5 and when I try to access http://10.62.194.5:30682 I do not get the nginx landing page.

One part I do not understand is that when I do kubectl describe node myserver1, in the long output I receive I can see:

Addresses:
  InternalIP:  10.62.194.5
  Hostname:    myserver1

Why does it say InternalIP? I can ping this IP
