Adding EZSSH Access to Endpoints With Cloud Init


  1. Have at least one policy with endpoints


EZSSH uses SSH Certificates to authenticate to endpoints. Since this is a OpenSSH supported protocol, no custom code has to run on your endpoints for authentication to work. By adding your EZSSH Certificate to your TrustedUserCAKeys your endpoint will start working with EZSSH.
