Functions ¶
func NewAPI ¶
func NewAPI(sess *session.Session, region string) pricingiface.PricingAPI
NewPricingAPI returns a pricing API configured based on a particular region
Types ¶
type Provider ¶
type Provider struct {
// contains filtered or unexported fields
}
Provider provides actual pricing data to the AWS cloud 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 NewProvider ¶
func NewProvider(ctx context.Context, pricing pricingiface.PricingAPI, ec2Api ec2iface.EC2API, region string, startAsync <-chan struct{}) *Provider
func (*Provider) InstanceTypes ¶
InstanceTypes returns the list of all instance types for which either a spot or on-demand price is known.
func (*Provider) OnDemandLastUpdated ¶
OnDemandLastUpdated returns the time that the on-demand pricing was last updated
func (*Provider) OnDemandPrice ¶
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 (*Provider) SpotLastUpdated ¶
SpotLastUpdated returns the time that the spot pricing was last updated
func (*Provider) SpotPrice ¶
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
