For best results, create a directory on your admin node node for maintaining the
configuration that ``ceph-deploy`` generates for your cluster. ::

	mkdir my-cluster
	cd my-cluster

.. tip:: The ``ceph-deploy`` utility will output files to the 
   current directory. Ensure you are in this directory when executing
   ``ceph-deploy``.
