Any restrictions on rootless containers?

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?
