CentOS 8 and derivatives
CentOS 8 / Oracle Linux 8 / AlmaLinux 8 / Rocky Linux 8 ship only with iptables-nft (ie without iptables-legacy similar to RHEL8)
The only tested configuration for now is using Calico CNI
You need 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.
An example how k8s do the autodetection can be found in this PR
