public class FleetLaunchTemplateOverridesRequest

The FleetLaunchTemplateOverridesRequest type exposes the following members



Public Property AvailabilityZone System.String

Gets and sets the property AvailabilityZone.

The Availability Zone in which to launch the instances.

Public Property ImageId System.String

Gets and sets the property ImageId.

The ID of the AMI. An AMI is required to launch an instance. This parameter is only available for fleets of type instant. For fleets of type maintain and request, you must specify the AMI ID in the launch template.

Public Property InstanceRequirements Amazon.EC2.Model.InstanceRequirementsRequest

Gets and sets the property InstanceRequirements.

The attributes for the instance types. When you specify instance attributes, Amazon EC2 will identify instance types with those attributes.

If you specify InstanceRequirements, you can't specify InstanceType.

Public Property InstanceType Amazon.EC2.InstanceType

Gets and sets the property InstanceType.

The instance type.

mac1.metal is not supported as a launch template override.

If you specify InstanceType, you can't specify InstanceRequirements.

Public Property MaxPrice System.String

Gets and sets the property MaxPrice.

The maximum price per unit hour that you are willing to pay for a Spot Instance. We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.

If you specify a maximum price, your instances will be interrupted more frequently than if you do not specify this parameter.

Public Property Placement Amazon.EC2.Model.Placement

Gets and sets the property Placement.

The location where the instance launched, if applicable.

Public Property Priority System.Double

Gets and sets the property Priority.

The priority for the launch template override. The highest priority is launched first.

If the On-Demand AllocationStrategy is set to prioritized, EC2 Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.

If the Spot AllocationStrategy is set to capacity-optimized-prioritized, EC2 Fleet uses priority on a best-effort basis to determine which launch template override to use in fulfilling Spot capacity, but optimizes for capacity first.

Valid values are whole numbers starting at 0. The lower the number, the higher the priority. If no number is set, the launch template override has the lowest priority. You can set the same priority for different launch template overrides.

Public Property SubnetId System.String

Gets and sets the property SubnetId.

The IDs of the subnets in which to launch the instances. Separate multiple subnet IDs using commas (for example, subnet-1234abcdeexample1, subnet-0987cdef6example2). A request of type instant can have only one subnet ID.

Public Property WeightedCapacity System.Double

Gets and sets the property WeightedCapacity.

The number of units provided by the specified instance type.

When specifying weights, the price used in the lowest-price and price-capacity-optimized allocation strategies is per unit hour (where the instance price is divided by the specified weight). However, if all the specified weights are above the requested TargetCapacity, resulting in only 1 instance being launched, the price used is per instance hour.
