This interface layer handles the communication between the Ceph Monitor and a client that requires an admin key.
This interface layer will set the following states, as appropriate:
{relation_name}.availableThe ceph client has been related to a provider. The following accessors will be available:
- key - The mds cephx key
- admin_key - The cephx admin key
- auth - Whether or not strict auth is supported
- mon_hosts - The public addresses list of the monitor cluster
Client example:
@when('ceph-mds.available')
def ceph_connected(ceph_info):
charm_ceph_conf = os.path.join(os.sep, 'etc', 'ceph', 'ceph.conf')
cephx_key = os.path.join(os.sep, 'etc', 'ceph', 'ceph.client.admin.keyring')
ceph_context = {
'auth_supported': ceph_client.auth,
'mon_hosts': ceph_client.mon_hosts,
}
with open(charm_ceph_conf, 'w') as cephconf:
cephconf.write(render_template('ceph.conf', ceph_context))
# Write out the cephx_key also
with open(cephx_key, 'w') as cephconf:
cephconf.write(ceph_client.key)
