autoscaling_attach_instances: Attaches one or more EC2 instances to the specified Auto Scaling group

Description

Attaches one or more EC2 instances to the specified Auto Scaling group.

Usage

autoscaling_attach_instances(InstanceIds, AutoScalingGroupName)

Arguments

InstanceIds

The IDs of the instances. You can specify up to 20 instances.

AutoScalingGroupName

[required] The name of the Auto Scaling group.

Request syntax

svc$attach_instances(
  InstanceIds = list(
    "string"
  ),
  AutoScalingGroupName = "string"
)

Details

When you attach instances, Amazon EC2 Auto Scaling increases the desired capacity of the group by the number of instances being attached. If the number of instances being attached plus the desired capacity of the group exceeds the maximum size of the group, the operation fails.

If there is a Classic Load Balancer attached to your Auto Scaling group, the instances are also registered with the load balancer. If there are target groups attached to your Auto Scaling group, the instances are also registered with the target groups.

For more information, see Attach EC2 Instances to Your Auto Scaling Group in the Amazon EC2 Auto Scaling User Guide.
