AsgCapacityProviderProps

class aws_cdk.aws_ecs.AsgCapacityProviderProps(*, can_containers_access_instance_role=None, machine_image_type=None, spot_instance_draining=None, task_drain_time=None, topic_encryption_key=None, auto_scaling_group, capacity_provider_name=None, enable_managed_scaling=None, enable_managed_termination_protection=None, maximum_scaling_step_size=None, minimum_scaling_step_size=None, target_capacity_percent=None)

Bases: AddAutoScalingGroupCapacityOptions

The options for creating an Auto Scaling Group Capacity Provider.

Parameters:

can_containers_access_instance_role (Optional[bool]) – Specifies whether the containers can access the container instance role. Default: false
machine_image_type (Optional[MachineImageType]) – What type of machine image this is. Depending on the setting, different UserData will automatically be added to the AutoScalingGroup to configure it properly for use with ECS. If you create an AutoScalingGroup yourself and are adding it via addAutoScalingGroup(), you must specify this value. If you are adding an autoScalingGroup via addCapacity, this value will be determined from the machineImage you pass. Default: - Automatically determined from machineImage, if available, otherwise MachineImageType.AMAZON_LINUX_2.
spot_instance_draining (Optional[bool]) – Specify whether to enable Automated Draining for Spot Instances running Amazon ECS Services. For more information, see Using Spot Instances. Default: false
task_drain_time (Optional[Duration]) – (deprecated) The time period to wait before force terminating an instance that is draining. This creates a Lambda function that is used by a lifecycle hook for the AutoScalingGroup that will delay instance termination until all ECS tasks have drained from the instance. Set to 0 to disable task draining. Set to 0 to disable task draining. Default: Duration.minutes(5)
topic_encryption_key (Optional[IKey]) – If {@link AddAutoScalingGroupCapacityOptions.taskDrainTime} is non-zero, then the ECS cluster creates an SNS Topic to as part of a system to drain instances of tasks when the instance is being shut down. If this property is provided, then this key will be used to encrypt the contents of that SNS Topic. See SNS Data Encryption for more information. Default: The SNS Topic will not be encrypted.
auto_scaling_group (IAutoScalingGroup) – The autoscaling group to add as a Capacity Provider.
capacity_provider_name (Optional[str]) – The name of the capacity provider. If a name is specified, it cannot start with aws, ecs, or fargate. If no name is specified, a default name in the CFNStackName-CFNResourceName-RandomString format is used. Default: CloudFormation-generated name
enable_managed_scaling (Optional[bool]) – Whether to enable managed scaling. Default: true
enable_managed_termination_protection (Optional[bool]) – Whether to enable managed termination protection. Default: true
maximum_scaling_step_size (Union[int, float, None]) – Maximum scaling step size. In most cases this should be left alone. Default: 1000
minimum_scaling_step_size (Union[int, float, None]) – Minimum scaling step size. In most cases this should be left alone. Default: 1
target_capacity_percent (Union[int, float, None]) – Target capacity percent. In most cases this should be left alone. Default: 100

Attributes

auto_scaling_group: The autoscaling group to add as a Capacity Provider.

can_containers_access_instance_role

Specifies whether the containers can access the container instance role.

Default:: false

capacity_provider_name

The name of the capacity provider.

If a name is specified, it cannot start with aws, ecs, or fargate. If no name is specified, a default name in the CFNStackName-CFNResourceName-RandomString format is used.

Default:: CloudFormation-generated name

enable_managed_scaling

Whether to enable managed scaling.

Default:: true

enable_managed_termination_protection

Whether to enable managed termination protection.

Default:: true

machine_image_type

What type of machine image this is.

Depending on the setting, different UserData will automatically be added to the AutoScalingGroup to configure it properly for use with ECS.

If you create an AutoScalingGroup yourself and are adding it via addAutoScalingGroup(), you must specify this value. If you are adding an autoScalingGroup via addCapacity, this value will be determined from the machineImage you pass.

Default:

Automatically determined from machineImage, if available, otherwise MachineImageType.AMAZON_LINUX_2.

maximum_scaling_step_size

Maximum scaling step size.

In most cases this should be left alone.

Default:: 1000

minimum_scaling_step_size

Minimum scaling step size.

In most cases this should be left alone.

Default:: 1

spot_instance_draining

Specify whether to enable Automated Draining for Spot Instances running Amazon ECS Services.

For more information, see Using Spot Instances.

Default:: false

target_capacity_percent

Target capacity percent.

In most cases this should be left alone.

Default:: 100

task_drain_time

(deprecated) The time period to wait before force terminating an instance that is draining.

This creates a Lambda function that is used by a lifecycle hook for the AutoScalingGroup that will delay instance termination until all ECS tasks have drained from the instance. Set to 0 to disable task draining.

Set to 0 to disable task draining.

Default:: Duration.minutes(5)
Deprecated:: The lifecycle draining hook is not configured if using the EC2 Capacity Provider. Enable managed termination protection instead.
Stability:: deprecated

topic_encryption_key

//docs.aws.amazon.com/sns/latest/dg/sns-data-encryption.html>`_ for more information.

Default:: The SNS Topic will not be encrypted.
Type:: If {@link AddAutoScalingGroupCapacityOptions.taskDrainTime} is non-zero, then the ECS cluster creates an SNS Topic to as part of a system to drain instances of tasks when the instance is being shut down. If this property is provided, then this key will be used to encrypt the contents of that SNS Topic. See `SNS Data Encryption <https
