Which kernel moduules are really needed for docker installation?

Question

I am trying to install docker on a dragonboard 410c and am getting an error when trying to run systemctl start docker:

failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain DOCKER: iptables failed: iptables --wait -t nat -N DOCKER: iptables v1.8.2 (nf_tables):  CHAIN_ADD failed (No such file or directory): chain PREROUTING

Having checked the necessary kernel modules using the script found here: https://github.com/moby/moby/blob/master/contrib/check-config.sh

I found that I was missing: NETFILTER_XT_MATCH_IPVS and several other optional kernel modules. However, after adding this module I am still getting the same error after installing docker. Do I need other "optional" kernel modules?

The problem in my case was not missing kernel modules, but debian buster using nftables instead of iptables for nat as described here:

The above mentioned solution (switching to legacy) worked for me:

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