Configuring Secure Shell (SSH) keys

Ansible uses Secure Shell (SSH) for connectivity between the deployment and target hosts.

1. Copy the contents of the public key file on the deployment host to the /root/.ssh/authorized_keys on each target host.
2. Test public key authentication from the deployment host to each target host. SSH should provide a shell without asking for a password.
