LaunchTemplateOverridesProperty()
public LaunchTemplateOverridesProperty()Properties
AvailabilityZone
The Availability Zone in which to launch the instances.
public string AvailabilityZone { get; set; }Property Value
System.String
Remarks
InstanceRequirements
The instance requirements.
public object InstanceRequirements { get; set; }Property Value
System.Object
Remarks
When you specify instance requirements, Amazon EC2 will identify instance types with the provided requirements, and then use 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 instance types.
If you specify InstanceRequirements , you can't specify InstanceType .
InstanceType
The instance type.
public string InstanceType { get; set; }Property Value
System.String
Remarks
Priority
The priority for the launch template override. The highest priority is launched first.
public Nullable<double> Priority { get; set; }Property Value
System.Nullable<System.Double>
Remarks
If OnDemandAllocationStrategy is set to prioritized , Spot Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.
If the Spot AllocationStrategy is set to capacityOptimizedPrioritized , Spot 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.
SpotPrice
The maximum price per unit hour that you are willing to pay for a Spot Instance.
public string SpotPrice { get; set; }Property Value
System.String
Remarks
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.
SubnetId
The ID of the subnet in which to launch the instances.
public string SubnetId { get; set; }Property Value
System.String
Remarks
WeightedCapacity
The number of units provided by the specified instance type.
public Nullable<double> WeightedCapacity { get; set; }Property Value
System.Nullable<System.Double>
Remarks
These are the same units that you chose to set the target capacity in terms of instances, or a performance characteristic such as vCPUs, memory, or I/O.
If the target capacity divided by this value is not a whole number, Amazon EC2 rounds the number of instances to the next whole number. If this value is not specified, the default is 1.
When specifying weights, the price used in the lowestPrice and priceCapacityOptimized 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.
