Hi! I’m currently attempting to profile an application running inside a docker container on a Jetson TX2, using
nvidia-docker. I would prefer to do this using the
perf tool, as the stats it provides are exactly what I need. Docker’s default security policy does not allow one to run
perf stat and similar commands inside a container. To be specific, the system call
perf relies on under the hood, called
perf_event_open is disabled by default. This should be easy to override using the
--security-opt flag to
docker run paired with a JSON file containing a modified list of permitted system calls. However, when attempting to run a Container with the specified settings, I get the following error message:
Error response from daemon: seccomp profiles are not supported on this daemon, you cannot specify a custom seccomp profile
Does anyone know of a way to specify a seccomp profile despite this? Is is possible/advisable to use a different docker runtime when profiling?
Thanks a lot in advance!
