resources

func Ceiling ¶

func Ceiling(pod *v1.Pod) v1.ResourceRequirements

Ceiling calculates the max between the sum of container resources and max of initContainers

func Cmp ¶

func Cmp(lhs resource.Quantity, rhs resource.Quantity) int

func Fits ¶

func Fits(candidate, total v1.ResourceList) bool

Fits returns true if the candidate set of resources is less than or equal to the total set of resources.

func IsZero ¶

func IsZero(r resource.Quantity) bool

IsZero implements r.IsZero(). This method is provided to make some code a bit cleaner as the Quantity.IsZero() takes a pointer receiver and map index expressions aren't addressable, so it can't be called directly.

func LimitsForPods ¶

func LimitsForPods(pods ...*v1.Pod) v1.ResourceList

LimitsForPods returns the total resources of a variadic list of podspecs

func MaxResources ¶

func MaxResources(resources ...v1.ResourceList) v1.ResourceList

MaxResources returns the maximum quantities for a given list of resources

func Merge ¶

func Merge(resources ...v1.ResourceList) v1.ResourceList

Merge the resources from the variadic into a single v1.ResourceList

func MergeResourceLimitsIntoRequests ¶

func MergeResourceLimitsIntoRequests(container v1.Container) v1.ResourceList

MergeResourceLimitsIntoRequests merges resource limits into requests if no request exists for the given resource

func Quantity ¶

func Quantity(value string) *resource.Quantity

Quantity parses the string value into a *Quantity

func RequestsForPods ¶

func RequestsForPods(pods ...*v1.Pod) v1.ResourceList

RequestsForPods returns the total resources of a variadic list of podspecs.

func String ¶

func String(list v1.ResourceList) string

String returns a string version of the resource list suitable for presenting in a log

func StringMap ¶

func StringMap(list v1.ResourceList) map[string]string

StringMap returns the string map representation of the resource list

func Subtract ¶

func Subtract(lhs, rhs v1.ResourceList) v1.ResourceList
