+
+Run `ssh-keygen` to create a key pair (naming example: `mydomain.com`) and transfer public key to remote host with `ssh-copy-id`.

+
+```
+Host mydomain.com
+  HostName virtual.server.com
+  User mydfhtsy
+  Port 22
+  IdentityFile ~/.ssh/mydomain.com
+```
+
+Setup the non-local host in the `inventory.yml` file.
