Create local ssh config

Generate keypair.

ssh-keygen -t rsa -N '' -f ~/.ssh/id_rsa -C "" <<< y

Push keys to Openstack nodes.

sshpass -p "Password0" ssh-copy-id -o StrictHostKeyChecking=no openstack@192.168.140.60

Create local ssh config, ansible targets node1 as control1 using this configuration.

nano -cw ~/.ssh/config
