Constants

const (
	// TODO(jonboulle): make these configurable
	HostCores  = 100
	HostMemory = 256
	HostDisk   = 0
)

Variables

var HostResources = ResourceTuple{
	HostCores,
	HostMemory,
	HostDisk,
}

HostResources represents a set of resources that fleet considers reserved for the host, i.e. outside of any units it is running

Types

type ResourceTuple

type ResourceTuple struct {
	// in hundreds, ie 100=1core, 50=0.5core, 200=2cores, etc
	Cores int
	// in MB
	Memory int
	// in MB
	Disk int
}

ResourceTuple groups together CPU, memory and disk space. This could be total, available or consumed. It could also be used by job resource requirements.

func Sub

func Sub(r1, r2 ResourceTuple) (res ResourceTuple)

Sub returns a ResourceTuple representing the difference between two ResourceTuples

func Sum

func Sum(resources ...ResourceTuple) (res ResourceTuple)

Sum aggregates a number of ResourceTuples into a single entity

func (ResourceTuple) Empty

func (rt ResourceTuple) Empty() bool

Empty returns true if all components of the ResourceTuple are zero.
