Description
===========
:program:`cephadm` is a command line tool to manage the local host for the cephadm orchestrator.
It provides commands to investigate and modify the state of the current host.
:program:`cephadm` is not required on all hosts, but useful when investigating a particular
daemon.
Options
=======
.. option:: --image IMAGE

"CEPHADM_IMAGE" env var (default: None)
.. option:: --docker
use docker instead of podman (default: False)
.. option:: --data-dir DATA_DIR
base directory for daemon data (default: /var/lib/ceph)
.. option:: --log-dir LOG_DIR
base directory for daemon logs (default: /var/log/ceph)
.. option:: --logrotate-dir LOGROTATE_DIR
location of logrotate configuration files (default: /etc/logrotate.d)
.. option:: --unit-dir UNIT_DIR
base directory for systemd units (default: /etc/systemd/system)
.. option:: --verbose, -v
Show debug-level log messages (default: False)
.. option:: --timeout TIMEOUT
timeout in seconds (default: None)
.. option:: --retry RETRY
max number of retries (default: 10)
.. option:: --no-container-init
do not run podman/docker with `--init` (default: False)

Configuration:
When starting the shell, cephadm looks for configuration in the following order.
Only the first values found are used:
1. An explicit, user provided path to a config file (``-c/--config`` option)
2. Config file for daemon specified with ``--name`` parameter (``/var/lib/ceph/<fsid>/<daemon-name>/config``)
3. ``/var/lib/ceph/<fsid>/config/ceph.conf`` if it exists
4. The config file for a ``mon`` daemon (``/var/lib/ceph/<fsid>/mon.<mon-id>/config``) if it exists
5. Finally: fallback to the default file ``/etc/ceph/ceph.conf``
bootstrap
