Ceph Deployment

The ceph-deploy tool is a way to deploy Ceph relying only upon SSH access tothe servers, sudo, and some Python. It runs on your workstation, and doesnot require servers, databases, or any other tools. If you set up andtear down Ceph clusters a lot, and want minimal extra bureaucracy,ceph-deploy is an ideal tool. The ceph-deploy tool is not a genericdeployment system. It was designed exclusively for Ceph users who want to getCeph up and running quickly with sensible initial configuration settings withoutthe overhead of installing Chef, Puppet or Juju. Users who want fine-controlover security settings, partitions or directory locations should use a toolsuch as Juju, Puppet, Chef or Crowbar.

With ceph-deploy, you can develop scripts to install Ceph packages on remotehosts, create a cluster, add monitors, gather (or forget) keys, add OSDs andmetadata servers, configure admin hosts, and tear down the clusters.
