How to prevent rogue docker containers from wreaking havoc? (alien.top)

There was a recent post about whether to enable ufw and it made me ask: how protected I am from a rogue docker container? I have a single server with 15-20 docker containers running at any given time. Should one get hacked or be malicious from the get go, are there (hopefully easy to implement for an armchair sysadmin) best practices to mitigate such an event? Thanks!

Safe-r. Not inherently safe. It's one good practice to consider among others. Like any measure that increases security, it makes your service less accessible - which may compromise usability or interoperability with other services.

You want to think through multiple security measures with any given service, decide what creates undo hassle, decide what's most important to you, limit the attack surface by making unauthorized access somewhere between inconvenient and near-impossible. And limit the damage that can be done if someone gets unauthorized access - ie not running as root, giving the container limited access to folders, etc.
