Brief Description:This article covers 3 Ubuntu machines, 1 Rke deployment Machines (192.168.3.161), 2 kubernetes cluster machines (3.162 and 3.163).On the Windows machine, download the rke_linux-amd64 from GitHub, rename it to Rke, edit the cluster.yml cluster deployment file, and upload the file to the 3.161 machine using the PSCP command provided by Putty. On the 3.161 machine, execute the rke command to deploy the cluster to the 3.162 and 3.163 mac
