Docker developers discuss changes in how ports are to be forwarded into containers
It took me a long time to notice this issue, and I've found this as a possible solution. Working on deploying it, and will see how it goes.

Self hosted security recommendations
Look into ufw (or iptables/nftables if you want to go deeper) to restrict outbound network access. Note though that Docker containers won't respect host firewall rules by default, so I created whalewall to easily manage container firewall rules: https://github.com/capnspacehook/whalewall
- Any experience with ufw-docker?

Whalewall - easily manage firewall rules for Docker containers
I recently found out that Docker containers ignore any host-based firewall rules by default and wanted a solution to restrict container traffic. This weekend I finally finished a project to do just that: https://github.com/capnspacehook/whalewall

Docker developers discuss changes in how ports are to be forwarded into containers
I know it looks daunting, but it's just putting ufw-style rules into your docker-compose files. There are other solutions like ufw docker automated , but they seem even more annoying to setup.

A Docker footgun led to a vandal deleting NewsBlur's MongoDB database
Luckily it was about as hardened as regular ftp can be, but I noticed the problem when my service wasn't able to log in as the (very low) connection limit was filled by someone attempting passwords.
I've been using https://github.com/shinebayar-g/ufw-docker-automated to make docker compliant with UFW, and defining firewall rules as labels for the containers.
