Constants

const DefaultMemoryRequest int64 = 200 * 1024 * 1024 // 200 MB

const DefaultMilliCpuRequest int64 = 100 // 0.1 core

For each of these resources, a pod that doesn't request the resource explicitly will be treated as having requested the amount indicated below, for the purpose of computing priority only. This ensures that when scheduling zero-request pods, such pods will not all be scheduled to the machine with the smallest in-use request, and that when scheduling regular pods, such pods will not see zero-request pods as consuming no resources whatsoever. We chose these values to be similar to the resources that we give to cluster addon pods (#10653). But they are pretty arbitrary. As described in #11713, we use request instead of limit to deal with resource requirements.

Functions

func GetNonzeroRequests

func GetNonzeroRequests(requests *api.ResourceList) (int64, int64)

GetNonzeroRequests returns the default resource request if none is found or what is provided on the request TODO: Consider setting default as a fixed fraction of machine capacity (take "capacity api.ResourceList" as an additional argument here) rather than using constants
