Group

class Group : KotlinCustomResource

Provides an Auto Scaling Group resource.

Note: You must specify either launch_configuration, launch_template, or mixed_instances_policy. NOTE on Auto Scaling Groups and ASG Attachments: This provider currently provides both a standalone aws.autoscaling.Attachment resource (describing an ASG attached to an ELB or ALB), and an aws.autoscaling.Group with load_balancers and target_group_arns defined in-line. These two methods are not mutually-exclusive. If aws.autoscaling.Attachment resources are used, either alone or with inline load_balancers or target_group_arns, the aws.autoscaling.Group resource must be configured to ignore changes to the load_balancers and target_group_arns arguments.

Mixed Instances Policy with Instance level LaunchTemplateSpecification Overrides

When using a diverse instance set, some instance types might require a launch template with configuration values unique to that instance type such as a different AMI (Graviton2), architecture specific user data script, different EBS configuration, or different networking configuration.

Waiting for Capacity

A newly-created ASG is initially empty and begins to scale to min_size (or desired_capacity, if specified) by launching instances using the provided Launch Configuration. These instances take time to launch and boot. On ASG Update, changes to these values also take time to result in the target number of instances providing service. This provider provides two mechanisms to help consistently manage ASG scale up time across dependent resources.

Waiting for ASG Capacity

The first is default behavior. This provider waits after ASG creation for min_size (or desired_capacity, if specified) healthy instances to show up in the ASG before continuing. If min_size or desired_capacity are changed in a subsequent update, this provider will also wait for the correct number of healthy instances before continuing. This provider considers an instance "healthy" when the ASG reports HealthStatus: "Healthy" and LifecycleState: "InService". See the [AWS AutoScaling

  • Docs](https://docs.aws.amazon.com/AutoScaling/latest/DeveloperGuide/AutoScalingGroupLifecycle.html) for more information on an ASG's lifecycle. This provider will wait for healthy instances for up to wait_for_capacity_timeout. If ASG creation is taking more than a few minutes, it's worth investigating for scaling activity errors, which can be caused by problems with the selected Launch Configuration. Setting wait_for_capacity_timeout to "0" disables ASG Capacity waiting.

Waiting for ELB Capacity

The second mechanism is optional, and affects ASGs with attached ELBs specified via the load_balancers attribute or with ALBs specified with target_group_arns. The min_elb_capacity parameter causes the provider to wait for at least the requested number of instances to show up "InService" in all attached ELBs during ASG creation. It has no effect on ASG updates. If wait_for_elb_capacity is set, the provider will wait for exactly that number of Instances to be "InService" in all attached ELBs on both creation and updates. These parameters can be used to ensure that service is being provided before the provider moves on. If new instances don't pass the ELB's health checks for any reason, the apply will time out, and the ASG will be marked as tainted (i.e., marked to be destroyed in a follow up run). As with ASG Capacity, the provider will wait for up to wait_for_capacity_timeout for the proper number of instances to be healthy.

Troubleshooting Capacity Waiting Timeouts

If ASG creation takes more than a few minutes, this could indicate one of a number of configuration problems. See the [AWS Docs on Load Balancer

  • Troubleshooting](https://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/elb-troubleshooting.html) for more information.

Import

Auto Scaling Groups can be imported using the name, e.g.,

$ pulumi import aws:autoscaling/group:Group web web-asg
Content copied to clipboard

Properties

Link copied to clipboard
val arn: Output<String>

ARN for this Auto Scaling Group

Link copied to clipboard
val availabilityZones: Output<List<String>>

List of one or more availability zones for the group. Used for EC2-Classic, attaching a network interface via id from a launch template and default subnets when not specified with vpc_zone_identifier argument. Conflicts with vpc_zone_identifier.

Link copied to clipboard
val capacityRebalance: Output<Boolean>?

Whether capacity rebalance is enabled. Otherwise, capacity rebalance is disabled.

Link copied to clipboard
val context: Output<String>?

Reserved.

Link copied to clipboard
val defaultCooldown: Output<Int>

Amount of time, in seconds, after a scaling activity completes before another scaling activity can start.

Link copied to clipboard
val defaultInstanceWarmup: Output<Int>?

Amount of time, in seconds, until a newly launched instance can contribute to the Amazon CloudWatch metrics. This delay lets an instance finish initializing before Amazon EC2 Auto Scaling aggregates instance metrics, resulting in more reliable usage data. Set this value equal to the amount of time that it takes for resource consumption to become stable after an instance reaches the InService state. (See Set the default instance warmup for an Auto Scaling group)

Link copied to clipboard
val desiredCapacity: Output<Int>

Number of Amazon EC2 instances that should be running in the group. (See also Waiting for Capacity below.)

Link copied to clipboard
val desiredCapacityType: Output<String>?

The unit of measurement for the value specified for desired_capacity. Supported for attribute-based instance type selection only. Valid values: "units", "vcpu", "memory-mib".

Link copied to clipboard
val enabledMetrics: Output<List<String>>?

List of metrics to collect. The allowed values are defined by the underlying AWS API.

Link copied to clipboard
val forceDelete: Output<Boolean>?

Allows deleting the Auto Scaling Group without waiting for all instances in the pool to terminate. You can force an Auto Scaling Group to delete even if it's in the process of scaling a resource. Normally, this provider drains all the instances before deleting the group. This bypasses that behavior and potentially leaves resources dangling.

Link copied to clipboard
val healthCheckGracePeriod: Output<Int>?

Time (in seconds) after instance comes into service before checking health.

Link copied to clipboard
val healthCheckType: Output<String>

"EC2" or "ELB". Controls how health checking is done.

Link copied to clipboard
val id: Output<String>
Link copied to clipboard
val initialLifecycleHooks: Output<List<GroupInitialLifecycleHook>>?

One or more Lifecycle Hooks to attach to the Auto Scaling Group before instances are launched. The syntax is exactly the same as the separate aws.autoscaling.LifecycleHook resource, without the autoscaling_group_name attribute. Please note that this will only work when creating a new Auto Scaling Group. For all other use-cases, please use aws.autoscaling.LifecycleHook resource.

val launchTemplate: Output<GroupLaunchTemplate>?

Nested argument with Launch template specification to use to launch instances. See Launch Template below for more details.

Link copied to clipboard
val loadBalancers: Output<List<String>>?

List of elastic load balancer names to add to the autoscaling group names. Only valid for classic load balancers. For ALBs, use target_group_arns instead.

val minSize: Output<Int>

Minimum size of the Auto Scaling Group. (See also Waiting for Capacity below.)
