Types

type DefaultProvider

type DefaultProvider struct {
	// contains filtered or unexported fields
}

DefaultProvider provides actual pricing data to the AlibabaCloud provider to allow it to make more informed decisions regarding which instances to launch. This is initialized at startup with a periodically updated static price list to support running in locations where pricing data is unavailable. In those cases the static pricing data provides a relative ordering that is still more accurate than our previous pricing model. In the event that a pricing update fails, the previous pricing information is retained and used which may be the static initial pricing data if pricing updates never succeed.

func NewDefaultProvider

func NewDefaultProvider(ctx context.Context, region string) (*DefaultProvider, error)

func (*DefaultProvider) InstanceTypes

func (p *DefaultProvider) InstanceTypes() []string

InstanceTypes returns the list of all instance types for which either a spot or on-demand price is known.

func (*DefaultProvider) LivenessProbe

func (p *DefaultProvider) LivenessProbe(_ *http.Request) error

func (*DefaultProvider) OnDemandPrice

func (p *DefaultProvider) OnDemandPrice(instanceType string) (float64, bool)

OnDemandPrice returns the last known on-demand price for a given instance type, returning an error if there is no known on-demand pricing for the instance type.

func (*DefaultProvider) Reset

func (p *DefaultProvider) Reset()

func (*DefaultProvider) SpotPrice

func (p *DefaultProvider) SpotPrice(instanceType string, zone string) (float64, bool)

SpotPrice returns the last known spot price for a given instance type and zone, returning an error if there is no known spot pricing for that instance type or zone

func (*DefaultProvider) UpdateOnDemandPricing

func (p *DefaultProvider) UpdateOnDemandPricing(ctx context.Context) error

func (*DefaultProvider) UpdateSpotPricing

func (p *DefaultProvider) UpdateSpotPricing(ctx context.Context) error
