Instance Attribute Summary

• #instance_requirements ⇒ Types::InstanceRequirements

  The instance requirements.

• #instance_type ⇒ String

  The instance type, such as m3.xlarge.

• #launch_template_specification ⇒ Types::LaunchTemplateSpecification

  Provides a launch template for the specified instance type or instance requirements.

• #weighted_capacity ⇒ String

  The number of capacity units provided by the instance type specified in InstanceType in terms of virtual CPUs, memory, storage, throughput, or other relative performance characteristic.

Instance Attribute Details

#instance_requirements ⇒ Types::InstanceRequirements

The instance requirements. When you specify instance requirements, Amazon EC2 Auto Scaling finds instance types that satisfy your requirements, and then uses your On-Demand and Spot allocation strategies to launch instances from these instance types, in the same way as when you specify a list of specific instance types.

Returns:

• (Types::InstanceRequirements)

# File 'gems/aws-sdk-autoscaling/lib/aws-sdk-autoscaling/types.rb', line 4986

class LaunchTemplateOverrides < Struct.new(
  :instance_type,
  :weighted_capacity,
  :launch_template_specification,
  :instance_requirements)
  SENSITIVE = []
  include Aws::Structure
end

#instance_type ⇒ String

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.

Returns:

• (String)

# File 'gems/aws-sdk-autoscaling/lib/aws-sdk-autoscaling/types.rb', line 4986

class LaunchTemplateOverrides < Struct.new(
  :instance_type,
  :weighted_capacity,
  :launch_template_specification,
  :instance_requirements)
  SENSITIVE = []
  include Aws::Structure
end

#launch_template_specification ⇒ Types::LaunchTemplateSpecification

Provides a launch template for the specified instance type or instance requirements. 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.

Returns:

• (Types::LaunchTemplateSpecification)

# File 'gems/aws-sdk-autoscaling/lib/aws-sdk-autoscaling/types.rb', line 4986

class LaunchTemplateOverrides < Struct.new(
  :instance_type,
  :weighted_capacity,
  :launch_template_specification,
  :instance_requirements)
  SENSITIVE = []
  include Aws::Structure
end

#weighted_capacity ⇒ String

The number of capacity units provided by the instance type specified in InstanceType in terms of virtual CPUs, memory, storage, throughput, or other relative performance characteristic. When a Spot or On-Demand Instance is launched, the capacity units count toward the desired capacity. Amazon EC2 Auto Scaling launches instances until the desired capacity is totally fulfilled, even if this results in an overage. For example, if there are two units remaining to fulfill capacity, and Amazon EC2 Auto Scaling can only launch an instance with a WeightedCapacity of five units, the instance is launched, and the desired capacity is exceeded by three units. For more information, see Configuring instance weighting for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide. Value must be in the range of 1–999.

Returns:

• (String)

# File 'gems/aws-sdk-autoscaling/lib/aws-sdk-autoscaling/types.rb', line 4986

class LaunchTemplateOverrides < Struct.new(
  :instance_type,
  :weighted_capacity,
