Terraform Example (aws_spot_fleet_request)

Provides an EC2 Spot Fleet Request resource. This allows a fleet of Spot instances to be requested on the Spot market.


Example Usage (from GitHub)

resource "aws_spot_fleet_request" "debian" {
  iam_fleet_role  = "arn:aws:iam::652694334613:role/aws-service-role/"
  target_capacity = 0

  # terminate_instances = true
  terminate_instances_with_expiration = true
resource "aws_spot_fleet_request" "master_nodes" {
  iam_fleet_role                      = "arn:aws:iam::345025288683:role/aws-ec2-spot-fleet-tagging-role"
  spot_price                          = var.master_bid
  allocation_strategy                 = "lowestPrice"
  target_capacity                     = 1
  valid_until                         = timeadd(timestamp(), var.spot_time)
resource "aws_spot_fleet_request" "test" {
  iam_fleet_role      = "arn:aws:iam::695507447459:role/aws-ec2-spot-fleet-tagging-role"

resource "aws_launch_template" "test_spot_fleet" {
  name_prefix = "spot-"
resource "aws_spot_fleet_request" "test" {
  iam_fleet_role                      = aws_iam_role.test.arn
  spot_price                          = "0.05"
  target_capacity                     = 1
  terminate_instances_with_expiration = true
  valid_until                         = "01/01/2222"
resource "aws_spot_fleet_request" "spot-ssm-example-spot-request" {
  iam_fleet_role = aws_iam_role.role.arn

  target_capacity                     = 1
  terminate_instances_with_expiration = true
  wait_for_fulfillment                = "true"

CloudFormation Example (AWS::EC2::SpotFleet)

Specifies a Spot Fleet request. A Spot Fleet request contains the configuration information to launch a fleet, or group, of instances.

The Spot Fleet request specifies the total target capacity and the On-Demand target capacity for the fleet. Amazon EC2 calculates the difference between the total capacity and On-Demand capacity, and launches the difference as Spot capacity.

The Spot Fleet request can include multiple launch specifications that vary by instance type, AMI, Availability Zone, or subnet.

By default, the Spot Fleet requests Spot Instances in the Spot pool where the price per unit is the lowest. Each launch specification can include its own instance weighting that reflects the value of the instance type to your application workload.

Alternatively, you can specify that the Spot Fleet distribute the target capacity across the Spot pools included in its launch specifications. By ensuring that the Spot Instances in your Spot Fleet are in different Spot pools, you can improve the availability of your fleet.

You can specify tags for the Spot Instances. You cannot tag other resource types in a Spot Fleet request because only the instance resource type is supported.

For more information, see Spot Fleet Requests in the Amazon EC2 User Guide for Linux Instances.
