nvprof in nvidia-docker permissions warning

Problem

I was running a CUDA application inside a nvidia-docker container. Wanting to profile it, I ran the application with nvprof and got a permissions warning and no profile information was generated:

==616== Warning: The user does not have permission to profile on the target device. See the following link for instructions to enable permissions and get more information: https://developer.nvidia.com/NVSOLN1000
==616== Warning: Some profiling data are not recorded. Make sure cudaProfilerStop() or cuProfilerStop() is called before application exit to flush profile data.

For another application, the error looked like this:

==643== NVPROF is profiling process 643, command: foobar
==643== Warning: The user does not have permission to profile on the target device. See the following link for instructions to enable permissions and get more information: https://developer.nvidia.com/NVSOLN1000
==643== Profiling application: foobar
==643== Profiling result:                                                                                                     
No kernels were profiled.                                                         
No API activities were profiled.

Solution

The warning message has a link, but perusing that documentation is not relevant to this docker problem. Solution turned out to be that I needed to add the --privileged option to my nvidia-docker command invocation.
