Dear all,

I want to run a process in a container with a real-time (RT) priority. When the sched_setscheduler(0, SCHED_RR, &sparam) is called in the container, an error is reported which is “operation not permitted”

I had added the following line in the file /etc/security/limits.conf for both the host and the container, which means allowing all users to change the priority of the process, but it still doesn’t work.

*     -        rtprio 100

I wonder how to change the privilege of a container so that it has the similar privilege of the root user of the host.

Thank you in advance

Cheng
