Description Juan Larriba 2022-07-05 12:56:51 UTC
In the control plane nodes, with Podman 4.0.2 established by compose RHOS-17.0-RHEL-9-20220628.n.1, the execution of any command is executed successfully, but a warning is displayed:

[heat-admin@controller-0 ~]$ podman info --format {{.Host.NetworkBackend}}
WARN[0000]  binary not found, container dns will not be enabled
netavark

The expected output should be the result, without the warning:

[heat-admin@controller-0 ~]$ podman info --format {{.Host.NetworkBackend}}
netavark

With network backend "netavark", the package "aardvark-dns" is needed, and it is currently not installed in the overcloud.

Can we please install "aardvark-dns" on the overcloud images?
