The DEVICE_LIST_STRATEGY flag allows one to choose which strategy the plugin will use to advertise the list of GPUs allocated to a container. This is traditionally done by setting the NVIDIA_VISIBLE_DEVICES environment variable as described here. This strategy can be selected via the (default) envvar option. Support has been added to the nvidia-container-toolkit to also allow passing the list of devices as a set of volume mounts instead of as an environment variable. This strategy can be selected via the volume-mounts option. Details for the rationale behind this strategy can be found here.
