    21

    23  setting                                  description

    26  /deis/store/fsid                         Ceph filesystem ID
    27  /deis/store/hosts/$HOST                  hostname (not IP) of the host running this store-monitor instance
    28  /deis/store/monKeyring                   keyring for the monitor to access the Ceph cluster
    29  /deis/store/monSetupComplete             set when the Ceph cluster setup is complete
    30  /deis/store/monSetupLock                 IP address of the monitor instance that is or has set up the Ceph cluster
    31  /deis/store/minSize                      minimum number of store-daemons necessary for the cluster to accept writes
    32  /deis/store/pgNum                        number of Ceph placement groups for the storage pools

    35  
    36  Settings used by store-monitor
    37  ------------------------------
    38  The store-monitor component uses no keys from etcd other than the ones it sets.
    39  
    40  Using a custom store-monitor image
    41  ----------------------------------
    42  You can use a custom Docker image for the store-monitor component instead of the image
    43  supplied with Deis:
    44  
    45  .. code-block:: console
    46  
    47      $ deisctl config store-monitor set image=myaccount/myimage:latest
    48  
    49  This will pull the image from the public Docker registry. You can also pull from a private
    50  registry:
    51  
    52  .. code-block:: console
    53  
    54      $ deisctl config store-monitor set image=registry.mydomain.org:5000/myaccount/myimage:latest
    55  
    56  Be sure that your custom image functions in the same way as the `stock store-monitor image`_ shipped with
    57  Deis. Specifically, ensure that it sets and reads appropriate etcd keys.
