Describes overrides for a launch template.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

instance_type: Option<InstanceType>

The instance type.

spot_price: Option<String>

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.

subnet_id: Option<String>

The ID of the subnet in which to launch the instances.

availability_zone: Option<String>

The Availability Zone in which to launch the instances.

weighted_capacity: Option<f64>

The number of units provided by the specified instance type. 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.

priority: Option<f64>

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

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.

instance_requirements: Option<InstanceRequirements>

The instance requirements. 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.

Implementations

impl LaunchTemplateOverrides

pub fn instance_type(&self) -> Option<&InstanceType>

The instance type.

pub fn spot_price(&self) -> Option<&str>

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.

pub fn subnet_id(&self) -> Option<&str>

The ID of the subnet in which to launch the instances.

pub fn availability_zone(&self) -> Option<&str>

The Availability Zone in which to launch the instances.

pub fn weighted_capacity(&self) -> Option<f64>

The number of units provided by the specified instance type. 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.

pub fn priority(&self) -> Option<f64>

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

impl LaunchTemplateOverrides

pub fn builder() -> LaunchTemplateOverridesBuilder

Creates a new builder-style object to manufacture LaunchTemplateOverrides.

Trait Implementations

impl Clone for LaunchTemplateOverrides

fn clone(&self) -> LaunchTemplateOverrides

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LaunchTemplateOverrides

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LaunchTemplateOverrides

fn eq(&self, other: &LaunchTemplateOverrides) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
