vagrant: services do not expose ports as expected

[fkautz]

Using the vagrant environment, I ran through the k8s startup tutorial to test the basic functionality and ran into a few problems around connectivity.

$ vagrant up

[truncate deployment/kubernetes-bootcamp creation]

# starts, but never replies to queries
$ kubectl proxy

# starts a service, but doesn't route packets to the pods
$ kubectl expose deployment/kubernetes-bootcamp --type="NodePort" --port 8080
$ kubectl get services

$ curl k8smaster:8080 # never responds

# After scaling to 4 pods:
kubectl get pods -o wide

@fkautz Can you please confirm whether the NodePort got created fine when you followed the instructions in the vagrant/README.md? i.e there is an example of apache and nginx. Did the curl $IP:Nodeport get you apache and nginx outputs?

$ curl k8smaster:8080 # never responds

Does the above work when you try it from outside the host?

The tip of OVS master is currently broken. I will try this after it gets fixed.

The tip of the OVS master is fixed. It should work now.
