```
[Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/) is an object storage interface built on top of [`librados`](https://docs.ceph.com/en/latest/rados/api/librados-intro/) to provide applications with a RESTful gateway to [Ceph Storage Clusters](https://docs.ceph.com/en/latest/rados/).
It provides object storage functionality with an interface that is compatible with a large subset of the Amazon S3 RESTful API.
## Terminology
% Include content from [storage_ceph.md](storage_ceph.md)
```{include} storage_ceph.md
:start-after: <!-- Include start Ceph terminology -->
:end-before: <!-- Include end Ceph terminology -->
```
A *Ceph Object Gateway* consists of several OSD pools and one or more *Ceph Object Gateway daemon* (`radosgw`) processes that provide object gateway functionality.
## `cephobject` driver in Incus
```{note}
The `cephobject` driver can only be used for buckets.
For storage volumes, use the {ref}`Ceph <storage-ceph>` or {ref}`CephFS <storage-cephfs>` drivers.
```
% Include content from [storage_ceph.md](storage_ceph.md)
```{include} storage_ceph.md
:start-after: <!-- Include start Ceph driver cluster -->
:end-before: <!-- Include end Ceph driver cluster -->
```
You must set up a `radosgw` environment beforehand and ensure that its HTTP/HTTPS endpoint URL is reachable from the Incus server or servers.
See [Manual Deployment](https://docs.ceph.com/en/latest/install/manual-deployment/) for information on how to set up a Ceph cluster and [Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/) on how to set up a `radosgw` environment.
The `radosgw` URL can be specified at pool creation time using the [`cephobject.radosgw.endpoint`](storage-cephobject-pool-config) option.
Incus uses the `radosgw-admin` command to manage buckets. So this command must be available and operational on the Incus servers.

:start-after: <!-- Include start Ceph driver remote -->
:end-before: <!-- Include end Ceph driver remote -->
```
% Include content from [storage_ceph.md](storage_ceph.md)
```{include} storage_ceph.md
:start-after: <!-- Include start Ceph driver control -->
:end-before: <!-- Include end Ceph driver control -->
```
## Configuration options
The following configuration options are available for storage pools that use the `cephobject` driver and for storage buckets in these pools.
(storage-cephobject-pool-config)=
### Storage pool configuration

:start-after: <!-- config group storage_cephobject-common start -->
:end-before: <!-- config group storage_cephobject-common end -->
```
### Storage bucket configuration
% Include content from [config_options.txt](../config_options.txt)
```{include} ../config_options.txt
:start-after: <!-- config group storage_bucket_cephobject-common start -->
:end-before: <!-- config group storage_bucket_cephobject-common end -->
