podman incompatible with nftables

Post by rob153 » 2020/10/17 15:12:43

Hi, I'm encountering the following issue when trying to do "podman run":

Code: Select all

ERRO[0001] Error adding network: failed to list iptables chains: running [/sbin/iptables -t filter -S --wait]: exit status 1: iptables v1.8.4 (nf_tables): table `filter' is incompatible, use 'nft' tool.
 
ERRO[0001] Error while adding pod to CNI network "podman": failed to list iptables chains: running [/sbin/iptables -t filter -S --wait]: exit status 1: iptables v1.8.4 (nf_tables): table `filter' is incompatible, use 'nft' tool.
It seems as though the version of podman coming with CentOS 8 is only compatible with iptables,
when at the same time it's recommended (as far as I understood) to use nftables on CentOS8?

Does anyone know how to work around this?

It's more mysterious still since iptables isn't even in el8 - it's a wrapper round nftables.
CentOS 6 will die in November 2020 - migrate sooner rather than later!

CentOS 5 is dead, do not use it.

Minor update: I now found a bug report about this:
https://github.com/containers/podman/issues/5352
So there seem to be fixes underway. Still not sure what to do about it until then. The puzzling part is that not more people are having this issue, it doesn't seem to be a particularly exotic constellation to have podman and nftables in use.
