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

# Request a Spot fleet
resource "aws_spot_fleet_request" "cheap_compute" {
    iam_fleet_role = "arn:aws:iam::12345678:role/spot-fleet"
    spot_price = "0.03"
    allocation_strategy = "diversified"
    target_capacity = 6
    valid_until = "2019-11-04T20:44:20Z"
    launch_specification {
        instance_type = "m4.10xlarge"
        ami = "ami-1234"
        spot_price = "2.793"
    }
    launch_specification {
        instance_type = "m4.4xlarge"
        ami = "ami-5678"
        key_name = "my-key"
        spot_price = "1.117"
        availability_zone = "us-west-1a"
        subnet_id = "subnet-1234"
        weighted_capacity = 35
        root_block_device {
            volume_size = "300"
            volume_type = "gp2"
        }
    }
}

~> NOTE: Terraform does not support the functionality where multiple subnet_id or availability_zone parameters can be specified in the same launch configuration block. If you want to specify multiple values, then separate launch configuration blocks should be used:

resource "aws_spot_fleet_request" "foo" {
    iam_fleet_role = "arn:aws:iam::12345678:role/spot-fleet"
    spot_price = "0.005"
    target_capacity = 2
    valid_until = "2019-11-04T20:44:20Z"
    launch_specification {
        instance_type = "m1.small"
        ami = "ami-d06a90b0"
        key_name = "my-key"
        availability_zone = "us-west-2a"
    }
    launch_specification {
        instance_type = "m3.large"
        ami = "ami-d06a90b0"
        key_name = "my-key"
        availability_zone = "us-west-2a"
    }
    depends_on = ["aws_iam_policy_attachment.test-attach"]
}

Argument Reference

Most of these arguments directly correspond to the offical API.

• iam_fleet_role - (Required) Grants the Spot fleet permission to terminate Spot instances on your behalf when you cancel its Spot fleet request using CancelSpotFleetRequests or when the Spot fleet request expires, if you set terminateInstancesWithExpiration.

• launch_specification - Used to define the launch configuration of the spot-fleet request. Can be specified multiple times to define different bids across different markets and instance types.

  Note: This takes in similar but not identical inputs as aws_instance. There are limitations on what you can specify (tags, for example, are not supported). See the list of officially supported inputs in the reference documentation. Any normal aws_instance parameter that corresponds to those inputs may be used.

• spot_price - (Required) The bid price per unit hour.

• target_capacity - The number of units to request. You can choose to set the target capacity in terms of instances or a performance characteristic that is important to your application workload, such as vCPUs, memory, or I/O.

• allocation_strategy - Indicates how to allocate the target capacity across the Spot pools specified by the Spot fleet request. The default is lowestPrice.

• excess_capacity_termination_policy - Indicates whether running Spot instances should be terminated if the target capacity of the Spot fleet request is decreased below the current size of the Spot fleet.

• terminate_instances_with_expiration - Indicates whether running Spot instances should be terminated when the Spot fleet request expires.

• valid_until - The end date and time of the request, in UTC ISO8601 format (for example, YYYY-MM-DDTHH:MM:SSZ). At this point, no new Spot instance requests are placed or enabled to fulfill the request. Defaults to 24 hours.

Attributes Reference

The following attributes are exported:

• id - The Spot fleet request ID
• spot_request_state - The state of the Spot fleet request.
