Hi, I was trying to run the Kubernetes setup documented in [1] to verify whether there were any documentation gaps.
Initially, I was facing an issue where the networking aspect was not getting automatically configured in VirtualBox. This was probably because I had an older version of VirtualBox, which did not get uninstalled properly etc. To overcome this issue I reinstalled the required software on another machine (OS X) and ran the steps in [1]. Now, there are no networking issues when accessing the master node. However, I am still faced with an issue with my Kubernetes cluster and I also can not download (pull) the Docker image to the master node.
