Compatibility and Stability
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.
This table shows which version pairs are expected to work or not work together:
Ceph |
Podman |
|||||
|---|---|---|---|---|---|---|
1.9 |
2.0 |
2.1 |
2.2 |
3.0 |
> 3.0 |

Note
While not all Podman versions have been actively tested against all Ceph versions, there are no known issues with using Podman version 3.0 or greater with Ceph Quincy and later releases.
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.
Stability
Cephadm is relatively stable but new functionality is still being added and bugs are occasionally discovered. If issues are found, please open a tracker issue under the Orchestrator component (https://tracker.ceph.com/projects/orchestrator/issues)
Cephadm support remains under development for the following features:
ceph-exporter deployment
stretch mode integration
monitoring stack (moving towards prometheus service discover and providing TLS)
RGW multisite deployment support (requires lots of manual steps currently)
cephadm agent
If a cephadm command fails or a service stops running properly, see Pausing or Disabling cephadm for instructions on how to pause the Ceph cluster’s background activity and how to disable cephadm.
