func (ResourceCalculator) ComputePodRequest ¶

func (r ResourceCalculator) ComputePodRequest(pod v1.Pod) v1.ResourceList

ComputePodRequest returns a v1.ResourceList that covers the largest width in each resource dimension. Because init-containers run sequentially, we collect the max in each dimension iteratively. In contrast, we sum the resource vectors for regular containers since they run simultaneously.

If Pod Overhead is specified and the feature gate is set, the resources defined for Overhead are added to the calculated Resource request sum

Example:

Pod:

InitContainers
  IC1:
    CPU: 2
    Memory: 1G
  IC2:
    CPU: 2
    Memory: 3G
Containers
  C1:
    CPU: 2
    Memory: 1G
  C2:
    CPU: 1
    Memory: 1G

Result: CPU: 3, Memory: 3G
