==================
Create a Cluster
==================
The first step in using Ceph with ``ceph-deploy`` is to create a new Ceph
cluster. A new Ceph cluster has:
- A Ceph configuration file, and
- A monitor keyring.
The Ceph configuration file consists of at least:
- Its own filesystem ID (``fsid``)
- The initial monitor(s) hostname(s), and
- The initial monitor(s) and IP address(es).
For additional details, see the `Monitor Configuration Reference`_.
The ``ceph-deploy`` tool also creates a monitor keyring and populates it with a
``[mon.]`` key. For additional details, see the `Cephx Guide`_.
Usage
-----
To create a cluster with ``ceph-deploy``, use the ``new`` command and specify
the host(s) that will be initial members of the monitor quorum. ::
ceph-deploy new {host [host], ...}
For example::
ceph-deploy new mon1.foo.com
ceph-deploy new mon{1,2,3}
The ``ceph-deploy`` utility will use DNS to resolve hostnames to IP
addresses. The monitors will be named using the first component of
the name (e.g., ``mon1`` above). It will add the specified host names
to the Ceph configuration file. For additional details, execute::
ceph-deploy new -h
