7 | ``cephadm`` deploys and manages a Ceph cluster. It does this by connecting the |
| 8 | manager daemon to hosts via SSH. The manager daemon is able to add, remove, and | |
| 9 | update Ceph containers. ``cephadm`` does not rely on external configuration | |
| 10 | tools such as Ansible, Rook, and Salt. | |
| 11 | ||
| 12 | ``cephadm`` manages the full lifecycle of a Ceph cluster. This lifecycle | |
| 13 | starts with the bootstrapping process, when ``cephadm`` creates a tiny | |
| 14 | Ceph cluster on a single node. This cluster consists of one monitor and | |
| 15 | one manager. ``cephadm`` then uses the orchestration interface ("day 2" | |
| 16 | commands) to expand the cluster, adding all hosts and provisioning all | |
| 17 | Ceph daemons and services. Management of this lifecycle can be performed | |
| 18 | either via the Ceph command-line interface (CLI) or via the dashboard (GUI). | |
| 19 | ||
| 20 | ``cephadm`` is new in Ceph release v15.2.0 (Octopus) and does not support older | |
| 9f95a23c TL |
21 | versions of Ceph. |
