Types ¶
type Filter ¶
type Filter interface {
FilterReject(instanceTypes []*cloudprovider.InstanceType) (kept []*cloudprovider.InstanceType, rejected []*cloudprovider.InstanceType)
Name() string
}
func CapacityBlockFilter ¶
func CapacityBlockFilter(requirements scheduling.Requirements) Filter
CapacityBlockFilter creates a filter which selects the instance type with the cheapest capacity block offering if the provided requirements are for a reserved launch and the provided instance types have a capacity block offering. This filter is required because CreateFleet does not accept multiple capacity blocks in a given request. Ref: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-fleet-launch-instances-capacity-blocks-walkthrough.html
func CapacityReservationTypeFilter ¶
func CapacityReservationTypeFilter(requirements scheduling.Requirements) Filter
CapacityReservationTypeFilter creates a Filter which ensures there aren't instance types with offerings from multiple capacity reservation types. This addresses a CreateFleet limitation, where we can only specify a single market type (i.e. "on-demand" or "capacity-block").
func CompatibleAvailableFilter ¶
func CompatibleAvailableFilter(requirements scheduling.Requirements, requests corev1.ResourceList) Filter
CompatibleAvailableFilter removes instance types which do not have any compatible, available offerings. Other filters should not be used without first using this filter.
func ExoticInstanceTypeFilter ¶
func ExoticInstanceTypeFilter(requirements scheduling.Requirements) Filter
ExoticInstanceTypeFilter will remove instances with GPUs and accelerators, along with metal instances, if doing so doesn't filter out all instance types. This ensures Karpenter only launches these instances if the NodeClaim explicitly requests them or all other compatible instance types are unavailable.
func ReservedOfferingFilter ¶
func ReservedOfferingFilter(requirements scheduling.Requirements) Filter
ReservedOfferingFilter creates a Filter which ensures there's only a single reserved offering per zone. This addresses a limitation of the CreateFleet API, which limits calls to specifying a single offering per pool. If there are multiple offerings in the same pool, the offering with the greatest capacity will be selected.
func SpotInstanceFilter ¶
func SpotInstanceFilter(requirements scheduling.Requirements) Filter
SpotInstanceFilter removes all instances with spot offerings which are more expensive than the cheapest compatible and available on-demand offering. This ensures we don't launch with a more expensive spot instance for a mixed-launch NodeClaim. Note that instance types with available, compatible reserved offerings will not be filtered out. NOTE: This filter assumes all provided instance types have compatible and available offerings
