# This example illustrates a Pod using Pod-Level Resources (spec.resources) to manage CPU allocations.
# Pod-level resources determine the total resource requests and limits for the entire Pod,
# including containers that do not use DRA claims (such as sidecar containers).
#
# Required Driver Configuration:
#   --cpu-device-mode: "grouped" (CPUs are grouped, e.g. by NUMA node, and exposed as consumable capacity).
#
# Note: Unlike container-level examples, when using Pod-level resources, DRA claim requests
# do not need to be replicated in the container's standard resource requests block. The Pod-level
# resources block determines the upper bound.
