CentOS 8 ships only with iptables-nft (ie without iptables-legacy)

The only tested configuration for now is using Calico CNI

You need to use K8S 1.17+ and to add `calico_iptables_backend: "NFT"` or `calico_iptables_backend: "Auto"` to your configuration

If you have containers that are using iptables in the host network namespace (`hostNetwork=true`),
|
|
|
|
|
you need to ensure they are using iptables-nft.
