Dedicated service user or not ? (jlai.lu)

Hi all !

As of today, I am running my services with rootless podman pods and containers. Each functional stack gets its dedicated user (user cloud runs a pod with nextcloud-fpm, nginx, postgresql...) with user mapping. Now, my thought were that if an attack can escape a container, it should be contained to a specific user.

Is it really meaningful ? With service users' home setup in /var/lib, it makes a lot of small stuff annoying and I wonder if the current setup is really worth it ?

You shouldn't have any user home for your services, you shouldn't even allow them to login at all. They should only have group access to resources they need, and containers should restrict what directories they have access to.
