Installing Podman on All Nodes

To ensure unified management and deployment of applications and improve deployment consistency and reliability, you need to install Podman on all nodes (ceph1 to ceph3 and client1 to client3 in this document).

  • Podman is used to deploy Ceph in a container. Ceph has requirements on the Podman versions. For details, see Table 1.
  • Ceph 17.2.7 requires Podman 2.0 or later. The Podman version in the openEuler-20.03-LTS-SP4 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.
  • If you want to manually create a container image with the minimum dependency, prepare an additional compilation node and install Podman on it.
