Default variables

# Set the package install state for distribution packages
# Options are 'present' and 'latest'
ceph_client_package_state: "latest"

# to use Ceph in OSA, you need to
# - have the needed pools and a client user (for glance, cinder and/or nova)
#   pre-provisioned in your ceph cluster; OSA assumes to have root access to
#   the monitor hosts
# - configure / overrules following defaults in osa's user config
# - some ceph specific vars are (also) part of other role defaults:
#   * glance
#   * nova
# - cinder gets configured with ceph if there are cinder backends defined with
#   the rbd driver (see openstack_user_config.yml.example)

# The ceph_pkg_source variable controls the install source for the Ceph packages.
# Valid values include:
#   * ceph This option installs Ceph from a repo.  Additional variables to
#          adjust items such as Ceph release and regional download mirror can be found
#          in vars/*.yml
#   * distro This options installs Ceph from the operating system's default repository and
#            unlike the other options does not attempt to manage package keys or add additional
#            package repositories.

# Path to local keyrings directory
# If you want to provide keyrings from existing files, because you do not have ssh access to the monitors
# set the path to the repository containing the keyrings files.
# ie : ceph_keyrings_dir: /etc/openstack_deploy/ceph-conf
# The filenames inside the keyring directory must be in the structure of client-name.keyring
# ie: /etc/openstack_deploy/ceph-conf
# cinder.keyring
