Types

type Config

type Config struct {
	// SimilarityConfig configures EC2 similarity matching algorithm.
	SimilarityConfig ec2.Config
	// OnDemandBaseCapacity the minimum amount of the Auto Scaling group's capacity that must be fulfilled by On-Demand Instances.
	// This base portion is provisioned first as your group scales. Defaults to 0 if not specified.
	// Set the value of OnDemandBaseCapacity in terms of the number of capacity units (VCPU), and not the number of instances.
	OnDemandBaseCapacity int64
	// OnDemandPercentageAboveBaseCapacity controls the percentages of On-Demand Instances and Spot Instances for your additional capacity
	// beyond OnDemandBaseCapacity. Expressed as a number (for example, 20 specifies 20% On-Demand Instances, 80% Spot Instances).
	// Defaults to 100 if not specified. If set to 100, only On-Demand Instances are provisioned.
	OnDemandPercentageAboveBaseCapacity int64
}

A Config is used for update configuration tuning

type Lister

type Lister interface {
	List(ctx context.Context, tags map[string]string) ([]*autoscaling.Group, error)
}

Lister interface contains methods to list EC2 Auto Scaling groups

func NewLister

func NewLister(role sts.AssumeRoleInRegion) Lister

NewLister creates a new Lister

type Updater

type Updater interface {
	CreateUpdateInput(context.Context, *autoscaling.Group) (*autoscaling.UpdateAutoScalingGroupInput, error)
	Update(context.Context, *autoscaling.Group) error
}

Updater interface contains methods for updating EC2 Auto Scaling groups

func NewUpdater

func NewUpdater(role sts.AssumeRoleInRegion, config Config) Updater

NewUpdater create new Updater
