# Overview
|
|
|
|
**WARNING**: This is an unofficial, untested, and experimental layer from
|
|
the community.
|
|
|
|
This interface layer handles the communication between the Ceph Monitor
|
|
and a client that requires an admin key.
|
|
|
|
# Usage
|
|
|
|
## Requires
|
|
|
|
This interface layer will set the following states, as appropriate:
|
|
|
|
* `{relation_name}.available` The ceph client has been related to a provider.
|
|
The following accessors will be available:
|
|
- key - The admin cephx key
|
|
- auth - Whether or not strict auth is supported
|
|
- mon_hosts - The public addresses list of the monitor cluster
|
|
|
|
|
|
Client example:
|
|
|
|
```python
|
|
@when('ceph-admin.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)
|
|
```
