AWS::EC2::SpotFleet

The AWS::EC2::SpotFleet resource creates a request for a collection of Spot instances. The Spot fleet attempts to launch the number of Spot instances to meet the target capacity that you specified. For more information, see Spot Instances in the Amazon EC2 User Guide for Linux Instances.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "Type" : "AWS::EC2::SpotFleet",
  "Properties" : {
    "SpotFleetRequestConfigData" : SpotFleetRequestConfigData
  }
}

YAML


Type: AWS::EC2::SpotFleet
Properties: 
  SpotFleetRequestConfigData:
    SpotFleetRequestConfigData

Properties

SpotFleetRequestConfigData

The configuration for a Spot fleet request.

Required: Yes

Type: Amazon EC2 SpotFleet SpotFleetRequestConfigData

Update requires: Some interruptions

Return Values

Ref

When the logical ID of this resource is provided to the Ref intrinsic function, Ref returns the resource name.

For more information about using the Ref function, see Ref.

Example

The following example creates a Spot fleet with two launch specifications. The weighted capacities are the same, so Amazon EC2 launches the same number of instances for each specification. For more information, see How Spot Fleet Works in the Amazon EC2 User Guide for Linux Instances.
