please include kernel module CONFIG_NETFILTER_XT_SET

[Jeffrey Forman]

To use kube-router as part of a kubernetes install, it requires kernel module CONFIG_NETFILTER_XT_SET build it makes use of the 'set' module in iptables.

Otherwise, since this kernel module is not built as a module nor included in the kernel itself, iptables complains:

root@prod-controller1:~# cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.3 LTS"

root@prod-controller1:~# /sbin/iptables -t nat -A POSTROUTING -m set --match-set kube-router-pod-subnets src -m set ! --match-set kube-router-pod-subnets dst -m set ! --match-set kube-router-node-ips dst -j MASQUERADE --wait
iptables: No chain/target/match by that name.

root@prod-controller1:/boot# grep XT_SET config-$(uname -r)
# CONFIG_NETFILTER_XT_SET is not set

To fix this situation, I would kindly request that CONFIG_NETFILTER_XT_SET be incldued, at minimum, as a module in the kvm kernel.

Thanks,

Kube-router code that shows the iptables parameters using the 'set' module:
