Installing Podman on All Physical Nodes

Podman is used to deploy Ceph in a container. Ceph has requirements on the Podman versions.

**Table 1** Mapping between Ceph versions and Podman versions
Ceph	Podman
Ceph	1.9	2.0	2.1	2.2	3.0	> 3.0
≤ 15.2.5	True	False	False	False	False	False
≥ 15.2.6	True	True	True	False	False	False
≥ 16.2.1	False	True	True	False	True	True
≥ 17.2.0	False	True	True	False	True	True
Note: True indicates compatible, and False indicates incompatible.

Ceph 17.2.7 requires Podman 2.0 or later. The Podman version in the openEuler-20.03-LTS-SP3 community source is 0.10.1. You need to manually update Podman to a later version. This section uses Podman 3.4.4 as an example.

Download the dependency tool.
```
yum install rpmdevtools
```
