The Kubernetes cluster info tool

This tool is a quick and dirty test of the client-go package (for Go clients talking to a Kubernetes cluster), at the moment this tool will fetch the number of pods, deployments and services in each namespace and then print this information to the user.

API authentication method are out of cluster and you need your kubeconfig file that holds the context information to initialize a client. The same file that kubectl uses.

More info about client-go and how to use it in various ways can be found here.

This tool is not done yet and it can only get better!
