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