You can set one up by following instructions here, or if you wish to use Vagrant, you can clone the repo here and run vagrant up. When you deploy Rancher server, you should Once you run above command on a new machine, the host(s) tries to contact the Rancher server with the key. The server then verifies the key and registers the agent. Based on the environment to which the
