KUBELET

Set KUBELET_EXTRA_ARGS=--node-ip=192.168.4.X --resolv-conf=/run/systemd/resolve/resolv.conf
                                             [ this part only on Ubuntu hosts]

Run
    sudo update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
    sudo update-alternatives --set iptables /usr/sbin/iptables-legacy

to switch to iptables. Uses nftables otherwise, which isn't suported.
