Properties

Readonly desiredSize

desiredSize: number = 2

The desired capacity is the initial capacity of the Auto Scaling group at the time of its creation and the capacity it attempts to maintain. It can scale beyond this capacity if you configure auto scaling. This number must be greater than or equal to the minimum size of the group and less than or equal to the maximum size of the group.

Readonly healthCheckGracePeriod

healthCheckGracePeriod: undefined | number = undefined

The amount of time, in seconds, that Amazon EC2 Auto Scaling waits before checking the health status of an EC2 instance that has come into service and marking it unhealthy due to a failed Elastic Load Balancing or custom health check. This is useful if your instances do not immediately pass these health checks after they enter the InService state. Defaults to 0 if unspecified.

Readonly healthCheckType

healthCheckType: undefined | "EC2" | "ELB" = undefined

The service to use for the health checks. The valid values are EC2 (default) and ELB. If you configure an Auto Scaling group to use load balancer (ELB) health checks, it considers the instance unhealthy if it fails either the EC2 status checks or the load balancer health checks.

Readonly launchTemplate

launchTemplate: string = ''

Information used to specify the launch template and version to use to launch instances.

Readonly maxSize

maxSize: number = 4

The maximum size of the group.

Readonly minSize

minSize: number = 0

The minimum size of the group.

Readonly name

name: string = ''

The name of the Auto Scaling group. This name must be unique per Region per account. The name can contain any ASCII character 33 to 126 including most punctuation characters, digits, and upper and lowercased letters. Note You cannot use a colon (:) in the name.

subnets

subnets: string[] = []

List of subnet names for a virtual private cloud (VPC) where instances in the Auto Scaling group can be created. These subnets should be created under the VPC in network-config.yaml.

targetGroups

targetGroups: undefined | string[] = undefined

Target group name array to associate with the Auto Scaling group. These names are from the target group set in the application. Instances are registered as targets with the target groups. The target groups receive incoming traffic and route requests to one or more registered targets.
