Amazonka.AutoScaling.Types.LaunchTemplateOverrides

Description

Documentation

data LaunchTemplateOverrides Source #

Describes an override for a launch template. The maximum number of instance types that can be associated with an Auto Scaling group is 40. The maximum number of distinct launch templates you can define for an Auto Scaling group is 20. For more information about configuring overrides, see Configuring overrides in the Amazon EC2 Auto Scaling User Guide.

See: newLaunchTemplateOverrides smart constructor.

Fields

weightedCapacity :: Maybe Text
The number of capacity units provided by the specified instance type in terms of virtual CPUs, memory, storage, throughput, or other relative performance characteristic. When a Spot or On-Demand Instance is provisioned, the capacity units count toward the desired capacity. Amazon EC2 Auto Scaling provisions instances until the desired capacity is totally fulfilled, even if this results in an overage. For example, if there are 2 units remaining to fulfill capacity, and Amazon EC2 Auto Scaling can only provision an instance with a WeightedCapacity of 5 units, the instance is provisioned, and the desired capacity is exceeded by 3 units. For more information, see Instance weighting for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide. Value must be in the range of 1 to 999.
instanceType :: Maybe Text
The instance type, such as m3.xlarge. You must use an instance type that is supported in your requested Region and Availability Zones. For more information, see Instance types in the Amazon Elastic Compute Cloud User Guide.
launchTemplateSpecification :: Maybe LaunchTemplateSpecification
Provides the launch template to be used when launching the instance type. For example, some instance types might require a launch template with a different AMI. If not provided, Amazon EC2 Auto Scaling uses the launch template that's defined for your mixed instances policy. For more information, see Specifying a different launch template for an instance type in the Amazon EC2 Auto Scaling User Guide.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:weightedCapacity:LaunchTemplateOverrides', launchTemplateOverrides_weightedCapacity - The number of capacity units provided by the specified instance type in terms of virtual CPUs, memory, storage, throughput, or other relative performance characteristic. When a Spot or On-Demand Instance is provisioned, the capacity units count toward the desired capacity. Amazon EC2 Auto Scaling provisions instances until the desired capacity is totally fulfilled, even if this results in an overage. For example, if there are 2 units remaining to fulfill capacity, and Amazon EC2 Auto Scaling can only provision an instance with a WeightedCapacity of 5 units, the instance is provisioned, and the desired capacity is exceeded by 3 units. For more information, see Instance weighting for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide. Value must be in the range of 1 to 999.

$sel:instanceType:LaunchTemplateOverrides', launchTemplateOverrides_instanceType - The instance type, such as m3.xlarge. You must use an instance type that is supported in your requested Region and Availability Zones. For more information, see Instance types in the Amazon Elastic Compute Cloud User Guide.

$sel:launchTemplateSpecification:LaunchTemplateOverrides', launchTemplateOverrides_launchTemplateSpecification - Provides the launch template to be used when launching the instance type. For example, some instance types might require a launch template with a different AMI. If not provided, Amazon EC2 Auto Scaling uses the launch template that's defined for your mixed instances policy. For more information, see Specifying a different launch template for an instance type in the Amazon EC2 Auto Scaling User Guide.
