This new version uses the same base image as kube-proxy
(k8s.gcr.io/build-image/debian-iptables)
This allow to automatically pick iptables-legacy or iptables-nft,
and be compatible with RHEL/CentOS 8

# RHEL / CentOS 8
|
|
|
|
RHEL / 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.
|
|
An example how k8s do the autodetection can be found [in this PR](https://github.com/kubernetes/kubernetes/pull/82966)
