    Additionally, OpenShift Container Platform calculates a limit to request ratio by dividing the limit by the request. This value should be a non-negative integer greater than 1. For example, if a container has cpu: 500 in the limit value, and cpu: 100 in the request value, then its limit to request ratio for cpu is 5.
