-The [Known limitations dcoument](./known-limitations.md) outlines that VPA (vpa-recommender in particular) is not aware of the cluster's maximum allocatable and can recommend resources which will not fit even the largest node in the cluster. This issue occurs even when the cluster uses the [Cluster Autoscaler](https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/FAQ.md#basics). The vpa-recommender's resource recommendation can exceed the allocatable of the largest node in the cluster. Hence, pod's will be unschedulable (in `Pending` state) and the pod wouldn't fit the cluster even if a new node is added by the Cluster Autoscaler.

 It is possible to mitigate this issue by specifying the `--container-recommendation-max-allowed-cpu` and `--container-recommendation-max-allowed-memory` flags of the vpa-recommender. These flags represent the global maximum amount of cpu/memory that will be recommended **for a container**. If the VerticalPodAutoscaler already defines a max allowed (`.spec.resourcePolicy.containerPolicies.maxAllowed`) then it takes precedence over the global max allowed. The global max allowed is merged to the VerticalPodAutoscaler's max allowed if VerticalPodAutoscaler's max allowed is specified only for cpu or memory. If the VerticalPodAutoscaler does not specify a max allowed and a global max allowed is specified, then the global max allowed is being used.
 
 The recommendation for computing the `--container-recommendation-max-allowed-cpu` and `--container-recommendation-max-allowed-memory` values for your cluster is to use the largest node's allocatable (`.status.allocatable` field of a node) minus the DaemonSet pods resource requests minus a safety margin:
