    18  // For each resource (memory, CPU) Kubelet supports three classes of containers.
    19  // Memory guaranteed containers will receive the highest priority and will get all the resources
    20  // they need.
    21  // Burstable containers will be guaranteed their request and can “burst” and use more resources
    22  // when available.
    23  // Best-Effort containers, which don’t specify a request, can use resources only if not being used
    24  // by other pods.
