  annotations:
    kubernetes.io/description: "A pod demonstrating a configuration that is rejected because exclusive containers consume the entire pod resource budget, leaving no resources for the remaining container in the shared pool."
spec:
  # At Pod level, the Pod has CPU request equal to limits and memory request
  # also equal to memory limits. The main-app and metrics-sidecar containers
  # meet the requirements for the Guaranteed QoS class at container level, and
  # the logging-sidecar container doesn't specify any resource request. Because
  # the Guaranteed containers consume the entire pod resource budget,
  # leaving 0 CPUs for the shared pool required by logging-sidecar, this pod
  # will be rejected at admission.
