Comment # 4 on bug 1206950 from Alexandre Vicenzi

I'm not able to reproduce this using a compose file that has `depends_on` and
`links` to another container. cni-plugin-dnsname is not installed on my
machine.

From the official README [1].

podman dnsname plugin: It is usually found in the podman-plugins or
podman-dnsname distro packages, those packages are not pulled by default and
you need to install them. This allows containers to be able to resolve each
other if they are on the same CNI network. This is not necessary when podman is
using netavark as a network backend.

Tumbleweed uses netavark, you can see it with `podman info`:

networkBackendInfo:
    backend: netavark

This is not an issue, if netavark is not used, you need to manually install an
additional package. Something to consider, as of 2023, the dnsname plugin is no
longer actively maintained, it reached EOL.
