Chapter 7. Cephx Notes

When cephx is enabled (it is by default), you must specify a user name or ID and a path to the keyring containing the corresponding key for the user. You may also add the CEPH_ARGS environment variable to avoid re-entry of the following parameters: 

rbd --id {user-ID} --keyring=/path/to/secret [commands]
rbd --name {username} --keyring=/path/to/secret [commands]
Copy to Clipboard Toggle word wrap

For example: 

rbd --id admin --keyring=/etc/ceph/ceph.keyring [commands]
rbd --name client.admin --keyring=/etc/ceph/ceph.keyring [commands]
Copy to Clipboard Toggle word wrap
Tip

Add the user and secret to the CEPH_ARGS environment variable so that you don’t need to enter them each time.
