getDefaultInstanceWarmup

public final Duration getDefaultInstanceWarmup()

Description copied from interface: CommonAutoScalingGroupProps

The 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.

To optimize the performance of scaling policies that scale continuously, such as target tracking and step scaling policies, we strongly recommend that you enable the default instance warmup, even if its value is set to 0 seconds

Default instance warmup will not be added if no value is specified

Default: None

Specified by:

getDefaultInstanceWarmup in interface CommonAutoScalingGroupProps

See Also:

• https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-default-instance-warmup.html

getDesiredCapacity

public final Number getDesiredCapacity()

Description copied from interface: CommonAutoScalingGroupProps

If the ASG has scheduled actions, don't reset unchanged group sizes.

Only used if the ASG has scheduled actions (which may scale your ASG up or down regardless of cdk deployments). If true, the size of the group will only be reset if it has been changed in the CDK app. If false, the sizes will always be changed back to what they were in the CDK app on deployment.

Default: true

Specified by:

getIgnoreUnmodifiedSizeProperties in interface CommonAutoScalingGroupProps

getInstanceMonitoring

public final Monitoring getInstanceMonitoring()

Description copied from interface: CommonAutoScalingGroupProps

The maximum duration applies to all current and future instances in the group. As an instance approaches its maximum duration, it is terminated and replaced, and cannot be used again.

You must specify a value of at least 604,800 seconds (7 days). To clear a previously set value, leave this property undefined.

Default: none

Specified by:

getMaxInstanceLifetime in interface CommonAutoScalingGroupProps

Default: 1

Specified by:

getMinCapacity in interface CommonAutoScalingGroupProps

getNewInstancesProtectedFromScaleIn

public final Boolean getNewInstancesProtectedFromScaleIn()

Description copied from interface: CommonAutoScalingGroupProps

Whether newly-launched instances are protected from termination by Amazon EC2 Auto Scaling when scaling in.

By default, Auto Scaling can terminate an instance at any time after launch when scaling in an Auto Scaling Group, subject to the group's termination policy. However, you may wish to protect newly-launched instances from being scaled in if they are going to run critical applications that should not be prematurely terminated.

This flag must be enabled if the Auto Scaling Group will be associated with an ECS Capacity Provider with managed termination protection.

Default: false

Specified by:

getNewInstancesProtectedFromScaleIn in interface CommonAutoScalingGroupProps

getNotifications

public final List<NotificationConfiguration> getNotifications()

Description copied from interface: CommonAutoScalingGroupProps

Configure autoscaling group to send notifications about fleet changes to an SNS topic(s).

Default: - No fleet change notifications will be sent.

Specified by:

getNotifications in interface CommonAutoScalingGroupProps

See Also:

• https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-as-group.html#cfn-as-group-notificationconfigurations

getSignals

public final Signals getSignals()

Description copied from interface: CommonAutoScalingGroupProps

Configure waiting for signals during deployment.

Use this to pause the CloudFormation deployment to wait for the instances in the AutoScalingGroup to report successful startup during creation and updates. The UserData script needs to invoke cfn-signal with a success or failure code after it is done setting up the instance.

Without waiting for signals, the CloudFormation deployment will proceed as soon as the AutoScalingGroup has been created or updated but before the instances in the group have been started.

For example, to have instances wait for an Elastic Load Balancing health check before they signal success, add a health-check verification by using the cfn-init helper script. For an example, see the verify_instance_health command in the Auto Scaling rolling updates sample template:

https://github.com/awslabs/aws-cloudformation-templates/blob/master/aws/services/AutoScaling/AutoScalingRollingUpdates.yaml

Default: - Do not wait for signals

Specified by:

getSignals in interface CommonAutoScalingGroupProps

getSpotPrice

public final String getSpotPrice()

Description copied from interface: CommonAutoScalingGroupProps

The maximum hourly price (in USD) to be paid for any Spot Instance launched to fulfill the request.

Spot Instances are launched when the price you specify exceeds the current Spot market price.

launchTemplate and mixedInstancesPolicy must not be specified when this property is specified

Default: none

Specified by:

getSpotPrice in interface CommonAutoScalingGroupProps

getSsmSessionPermissions

public final Boolean getSsmSessionPermissions()

Description copied from interface: CommonAutoScalingGroupProps

Add SSM session permissions to the instance role.

Setting this to true adds the necessary permissions to connect to the instance using SSM Session Manager. You can do this from the AWS Console.

NOTE: Setting this flag to true may not be enough by itself. You must also use an AMI that comes with the SSM Agent, or install the SSM Agent yourself. See Working with SSM Agent in the SSM Developer Guide.

Default: false

Specified by:

getSsmSessionPermissions in interface CommonAutoScalingGroupProps

getTerminationPolicies

public final List<TerminationPolicy> getTerminationPolicies()

Description copied from interface: CommonAutoScalingGroupProps

What to do when an AutoScalingGroup's instance configuration is changed.

This is applied when any of the settings on the ASG are changed that affect how the instances should be created (VPC, instance type, startup scripts, etc.). It indicates how the existing instances should be replaced with new instances matching the new config. By default, nothing is done and only new instances are launched with the new config.

Default: - `UpdatePolicy.rollingUpdate()` if using `init`, `UpdatePolicy.none()` otherwise

Specified by:

getUpdatePolicy in interface CommonAutoScalingGroupProps

getVpcSubnets
