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 use rootless Podman, because security. A container breakout exploit will only impact that one Unix user. Plus no Docker daemon to worry about.

    I don’t seperate services into separate users, although maybe I should. The main impediment with separation is that you give up the conveniences of container networking / container DNS and have to connect everything on the host instead. I don’t know if that’s even possible (conveniently) with a service like Traefik that’s supposed to introspect running containers. Also, with separation by Unix user, there’s not one convenient place to SSH in and run podman ps or docker ps to see all containers. Maybe not a big deal?

    Auto-update of containers: No, I don’t, because updates somtimes break things and I want to be there in case something goes wrong. The one exception is I auto-update the containers I develop myself as the last implicit deployment step of a CI pipeline.

      +1 for rootless Podman. Kubernetes YAMLs to define pods, which are started/controlled by systemd. SELinux for added security.

      Also +1 for not using auto updates. Using the latest tag has bit me more times I can count, now I only use it for testing new stuff. All the important services have at least the major version as tag.
