===========================
Compatibility and Stability
===========================
.. _cephadm-compatibility-with-podman:
Compatibility with Podman Versions
----------------------------------
Podman and Ceph have different end-of-life strategies. This means that care
must be taken in finding a version of Podman that is compatible with Ceph.
These versions are expected to work:
+-----------+---------------------------------------+
| Ceph | Podman |
+-----------+-------+-------+-------+-------+-------+
| | 1.9 | 2.0 | 2.1 | 2.2 | 3.0 |
+===========+=======+=======+=======+=======+=======+
| <= 15.2.5 | True | False | False | False | False |
+-----------+-------+-------+-------+-------+-------+
| >= 15.2.6 | True | True | True | False | False |
+-----------+-------+-------+-------+-------+-------+
| >= 16.2.1 | False | True | True | False | True |
+-----------+-------+-------+-------+-------+-------+
.. warning::
To use Podman with Ceph Pacific, you must use **a version of Podman that
is 2.0.0 or higher**. However, **Podman version 2.2.1 does not work with
Ceph Pacific**.
"Kubic stable" is known to work with Ceph Pacific, but it must be run
with a newer kernel.
.. _cephadm-stability:
Stability
---------
Cephadm is under development. Some functionality is incomplete. Be aware
that some of the components of Ceph may not work perfectly with cephadm.
These include:
- RGW
Cephadm support remains under development for the following features:
- Ingress
- Cephadm exporter daemon
- cephfs-mirror
If a cephadm command fails or a service stops running properly, see
:ref:`cephadm-pause` for instructions on how to pause the Ceph cluster's
background activity and how to disable cephadm.
