I am working with the Vagrant Kubernetes 0.9.3 setup on Mac OSX.

Environment:

• Kubernetes 0.9.3
• Vagrant 1.7.2
• VirtualBox-4.3.20-96996-OSX

I am able to successfully deploy images and start containers in a single minion environment:

master

minion-1

I am unable to access the Internet from inside a running container. I can access the Internet from the minion-1 machine.

I setup the environment using Vagrant

/kubernetes$ export KUBERNETES_PROVIDER=vagrant
/kubernetes$ vagrant up

...(initialization logs and successful setup of master + minion-1 in Virtualbox)

ssh into the minion-1 machine to ensure Internet connectivity

/kubernetes$ vagrant ssh minion-1
[vagrant@kubernetes-minion-1 ~]$ ping google.com
PING google.com (173.194.123.37) 56(84) bytes of data.

The previous was successful in connecting

Below you can see that the container does not seem to be able to access the Internet.

Is this a problem with the Vagrant setup or is this intentional in the Kubernetes framework? If so, what is the proper way to access the Internet?
