# Ceph Client CRD
|
|
|
|
Rook allows creation and updating clients through the custom resource definitions (CRDs).
|
|
For more information about user management and capabilities see the [Ceph docs](https://docs.ceph.com/docs/master/rados/operations/user-management/).
|
|
|
|
## Use Case
|
|
|
|
Use Client CRD in case you want to integrate Rook with with applications that are using LibRBD directly.
|
|
For example for OpenStack deployment with Ceph backend use Client CRD to create OpenStack services users.
|
|
|
|
Don't use Client CRD for Flex or CSI driver users, they are created automatically.
|
|
|
|
## Creating Ceph User
|
|
|
|
To get you started, here is a simple example of a CRD to configure a Ceph client with capabilities.
|
|
|
|
```yaml
|
|
apiVersion: ceph.rook.io/v1
|
|
kind: CephClient
|
|
metadata:
|
|
name: glance
|
|
namespace: rook-ceph
|
|
spec:
|
|
caps:
|
|
mon: 'profile rbd'
|
|
osd: 'profile rbd pool=images'
|

|
|
apiVersion: ceph.rook.io/v1
|
|
kind: CephClient
|
|
metadata:
|
|
name: cinder
|
|
namespace: rook-ceph
|
|
spec:
|
|
caps:
|
|
mon: 'profile rbd'
|
|
osd: 'profile rbd pool=volumes, profile rbd pool=vms, profile rbd-read-only pool=images'
|
|
```
|
|
|
