Docker-compose with ufw-docker in Ubuntu 20.04

Introduction

During development using docker-compose on Ubuntu, I realized something weird was happening with my UFW. It just did not work as it should. Publishing ports in docker-compose just overrid any UFW settings.

Needless to say, this is not desirable. And it turns out it is not even that easy to solve. The current best solution i have found is ufw-docker

Quick Start

  1. Download the script

    sudo wget -O /usr/local/bin/ufw-docker \
    https://github.com/chaifeng/ufw-docker/raw/master/ufw-docker
    sudo chmod +x /usr/local/bin/ufw-docker
    sudo ufw-docker install
    sudo ufw-docker allow traefik 443
    sudo ufw-docker delete allow traefik 443

    Note! If you use docker-compose down and docker-compose up, the ip-address of the container might change, and you need to repeat the process.
