Types

type UnavailableOfferings

type UnavailableOfferings struct {
	SeqNum uint64
	// contains filtered or unexported fields
}

UnavailableOfferings stores any offerings that return ICE (insufficient capacity errors) when attempting to launch the capacity. These offerings are ignored as long as they are in the cache on GetInstanceTypes responses

func NewUnavailableOfferings

func NewUnavailableOfferings() *UnavailableOfferings

func NewUnavailableOfferingsWithCache

func NewUnavailableOfferingsWithCache(c *cache.Cache) *UnavailableOfferings

func (*UnavailableOfferings) Flush

func (u *UnavailableOfferings) Flush()

func (*UnavailableOfferings) IsUnavailable

func (u *UnavailableOfferings) IsUnavailable(instanceType, zone, capacityType string) bool

IsUnavailable returns true if the offering appears in the cache

func (*UnavailableOfferings) MarkSpotUnavailableWithTTL

func (u *UnavailableOfferings) MarkSpotUnavailableWithTTL(ctx context.Context, ttl time.Duration)

MarkSpotUnavailable communicates recently observed temporary capacity shortages for spot

func (*UnavailableOfferings) MarkUnavailable

func (u *UnavailableOfferings) MarkUnavailable(ctx context.Context, unavailableReason, instanceType, zone, capacityType string)

MarkUnavailable communicates recently observed temporary capacity shortages in the provided offerings

func (*UnavailableOfferings) MarkUnavailableWithTTL

func (u *UnavailableOfferings) MarkUnavailableWithTTL(ctx context.Context, unavailableReason, instanceType, zone, capacityType string, ttl time.Duration)

MarkUnavailableWithTTL allows us to mark an offering unavailable with a custom TTL
