# This playbook configures the Ceph repository.
# It also installs some prerequisites (podman, lvm2, chronyd, cephadm, ...)
#
# Usage:
#
# ansible-playbook -i <inventory host file> cephadm-preflight.yml
#
# You can limit the execution to a set of hosts by using `--limit` option:
#
# ansible-playbook -i <inventory host file> cephadm-preflight.yml --limit <my_osd_group|my_node_name>
#
# You can override variables using `--extra-vars` parameter:
#
# ansible-playbook -i <inventory host file> cephadm-preflight.yml --extra-vars "ceph_origin=rhcs"
