Not happy with Docker modifying your precious firewall rules?

• Docker inserts iptables rules when it's started by default
• buster uses nftables by default
• let's make Docker use nftables instead
• PROFIT

Prerequisites

Install Docker CE and nftables:

goll

#!/bin/bash

src=$1
dest=$2

awk '
  NR == FNR {
    if (NF >= 9) {
      data[$2] = $3 FS $4 FS $5
    }
