How do you host your container services?
How do you host your container services?
Do you host all services just from your root account with docker or do you seperate the services between user accounts with rootless docker?
Do you use podman or docker?
It's easier to just host everything from root with normal docker, but seperating services into special user account is probably way saver, at least as far as i know. Do you think ist worth going the extra step or do you just trust docker and your containers to not get exploited?
Last but not least do you use an automatic update service for your host system and your containers?

I keep all my services in one docker-compose yml, and run it from a normal user account added to the docker group.
I am really conscious of what I expose to the internet though, since I already almost had a security incident.
I used to run non-standard ssh port to my machine with password authentication enabled.
Turns out I didn't know the sonarr/radarr containers came with default users, and a bruteforce attack managed to login to one of them (or something like that anyway,it's been awhile). Fortunately they have a default home of /sbin/nologin so crisis averted there, but it definitely was a big lesson for me.
Years later, the current setup is only plex, tautulli, and ombi open to the internet, and to reach everything else I use tailscale. And of course,only key-based authentication.
Oh and for updates, I run apt upgrade once in a while on the box (Ubuntu server 18.04 LTS) and for the containers, I use watchtower.
