Any restrictions on rootless containers?

[inliquid]

Hi,

we have gops installed along the main binary in a container in a number of containerized services. The binary sets up gops agent, so the tool can communicate with running program over a TCP port. We would like to switch to rootless containers, so after that both service itself (running an agent) and gops will be run without root privileges.

Does running without root affect gops mechanics in any way (like accessing /proc for some specific metrics)? If there are any specific capabilities required, could you please point out which ones?
