Are you Avoiding --privileged? (Q3)

Demo shows --privileged turns on Linux capabilities and mounts all host devices, equivalent to adding every capability so a compromised container can load kernel modules or reformat host disks. Docker’s default gives a smaller sensible capability set and most apps need far fewer capabilities than assigned. Containers run as root inside container by default, so not using --privileged matters more than just avoiding a "root" label.
