Hi Ceph, Configuring a Ceph cluster requires sharing data between clients and daemons. It would be helpful for the architecture of a puppet module to have a detailed descripiton of what these requirements are. As far as I understand there is: * The IP address of at least one MON in the Ceph cluster If cephx is disabled: * no other requirement If cephx is enabled: * an admin user is created by providing a keyring file with its description when the first MON is bootstraped http://ceph.com/docs/next/dev/mon-bootstrap/ * users must be created by injecting them into the MONs, for instance with auth import https://github.com/ceph/ceph/blob/master/src/mon/MonCommands.h#L162 or auth add. There is not need to ask the MONs for a key, although it can be done. It is not a requirement. When a user is created or later on, its capabilities can be set. * an osd must be created by the mon which return an unique osd ID which is then used to further configure the osd. https://github.com/ceph/ceph/blob/master/src/mon/MonCommands.h#L471 * a client must be given a user id and a secret key It would also be helpful to better understand why people are happy with the way ceph-deploy currently works and how it deals with these requirements.
