Switch to CNI (quay.io/podman/stable)

[rkoo19]

Hi, thank you in advance for your help.

I am using the quay.io/podman/stable:latest image and was unable to use CNI in place of Netavark.

I've modified my /etc/containers/containers.conf to include network_backend="cni" under [network], but running podman info afterwards results in an error of cni support is not enabled in this build, only netavark.

we are trying to move away from CNI. IIRC, CNI is now controlled solely by a build tag (@Luap99 or @mheon can confirm this). Perhaps the question that needs to be worked on is why do you need CNI in the first place? Maybe from there, we can help.

CNI is deprecated and no longer in the default builds for any OS that is not RHEL 9 or FreeBSD as of Podman 5. Given the stable image is now on 5.4, it should not have had CNI for over a year now. We do not have intention of re-enabling CNI support given CNI upstream is making changes to better support the needs of Kubernetes. These changes are unfortunately moving CNI in a direction where it is very difficult for Podman to continue using it.
