What Happens when you type kubectl create namespace command?

func main() {
    command := cmd.NewDefaultKubectlCommand()
    if err := cli.RunNoErrOutput(command); err != nil {
        // Pretty-print the error and exit with an error.
        util.CheckErr(err)
    }
}

kubectl controls the Kubernetes cluster manager.
