Take a look to the user guide of ironic, they provide 2 diagrams with the architecture and explain how it works: http://docs.openstack.org/developer/ironic/deploy/user-guide.html# Regards! 2014-06-04 13:20 GMT+02:00 严超 <yanchao727 at gmail.com>: > Hi, All: > I searched a lot about how ironic automatically install image on > bare metal.
