Properties

NameTypeDescription
availabilityZone?stringThe Availability Zone in which to launch the instances.
instanceRequirements?IResolvable | InstanceRequirementsRequestPropertyThe attributes for the instance types.
instanceType?stringThe instance type.
maxPrice?stringThe maximum price per unit hour that you are willing to pay for a Spot Instance.
placement?IResolvable | PlacementPropertyThe location where the instance launched, if applicable.
priority?numberThe priority for the launch template override. The highest priority is launched first.
subnetId?stringThe IDs of the subnets in which to launch the instances.
weightedCapacity?numberThe number of units provided by the specified instance type.

availabilityZone?

Type: string (optional)

The Availability Zone in which to launch the instances.


instanceRequirements?

Type: IResolvable | InstanceRequirementsRequestProperty (optional)

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 .


instanceType?

Type: string (optional)

The instance type.

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

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


maxPrice?

Type: string (optional)

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.


placement?

Type: IResolvable | PlacementProperty (optional)

The location where the instance launched, if applicable.


priority?

Type: number (optional)

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.


subnetId?

Type: string (optional)

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.


weightedCapacity?

Type: number (optional)

The number of units provided by the specified instance type.
