Kubernetes: How can I get which pod schedule GPU?

Here's the example given from a kubectl plugin, kubectl-view-allocations:

> kubectl-view-allocations -r gpu

 Resource                   Requested       Limit  Allocatable  Free
  nvidia.com/gpu           (71%) 10.0  (71%) 10.0         14.0   4.0
  ├─ node-gpu1               (0%)  __    (0%)  __          2.0   2.0
  ├─ node-gpu2               (0%)  __    (0%)  __          2.0   2.0
  ├─ node-gpu3             (100%) 2.0  (100%) 2.0          2.0    __

Seems to offer what you are looking for.

Furthermore apparently, sharing GPUs is possible (with Nvidia-provided software) - might be useful to you or whoever finds this in the future:
