   2  Admin Tasks
   3 =============

   5 Once you have set up a cluster with ``ceph-deploy``, you may
   6 provide the client admin key and the Ceph configuration file
   7 to another host so that a user on the host may use the ``ceph``
   8 command line as an administrative user.

  11 Create an Admin Host
  12 ====================
  13
  14 To enable a host to execute ceph commands with administrator
  15 privileges, use the ``admin`` command. ::
  16
  17         ceph-deploy admin {host-name [host-name]...}

  20 Deploy Config File
  21 ==================
  22
  23 To send an updated copy of the Ceph configuration file to hosts
  24 in your cluster, use the ``config push`` command. ::
  25
  26         ceph-deploy config push {host-name [host-name]...}
  27
  28 .. tip:: With a base name and increment host-naming convention,
  29    it is easy to deploy configuration files via simple scripts
  30    (e.g., ``ceph-deploy config hostname{1,2,3,4,5}``).
  31
  32 Retrieve Config File
  33 ====================
  34
  35 To retrieve a copy of the Ceph configuration file from a host
  36 in your cluster, use the ``config pull`` command. ::
  37
  38         ceph-deploy config pull {host-name [host-name]...}
