Functions ¶

func Run ¶

func Run(cfg *Config)

Run starts processing all AWS regions looking for AutoScaling groups enabled and taking action by replacing more pricy on-demand instances with compatible and cheaper spot instances.

Types ¶

type Config ¶

type Config struct {

	// Static data fetched from ec2instances.info
	InstanceData *ec2instancesinfo.InstanceData

	// Logging
	LogFile io.Writer
	LogFlag int

	// The region where the Lambda function is deployed
	MainRegion string

	MinOnDemandNumber       int64
	MinOnDemandPercentage   float64
	Regions                 string
	AllowedInstanceTypes    string
	OnDemandPriceMultiplier float64

	// This is only here for tests, where we want to be able to somehow mock
	// time.Sleep without actually sleeping. While testing it defaults to 0 (which won't sleep at all), in
	// real-world usage it's expected to be set to 1
	SleepMultiplier time.Duration
}

Config contains a number of flags and static data storing the EC2 instance information.
