Overview Note:

When passing InstanceTypeConfig as input to an Aws::Client method, you can use a vanilla Hash:

{
  instance_type: "InstanceType",   weighted_capacity: 1,
  bid_price: "XmlStringMaxLen256",
  bid_price_as_percentage_of_on_demand_price: 1.0,
  ebs_configuration: {
    ebs_block_device_configs: [
      {
        volume_specification: {           volume_type: "String",           iops: 1,
          size_in_gb: 1,         },
        volumes_per_instance: 1,
      },
    ],
    ebs_optimized: false,
  },
  configurations: [
    {
      classification: "String",
      configurations: {
              },
      properties: {
        "String" => "String",
      },
    },
  ],
}

An instance type configuration for each instance type in an instance fleet, which determines the EC2 instances Amazon EMR attempts to provision to fulfill On-Demand and Spot target capacities. There can be a maximum of 5 instance type configurations in a fleet.

The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.

Instance Attribute Summary collapse

#bid_price ⇒ String The bid price for each EC2 Spot instance type as defined by InstanceType.
#bid_price_as_percentage_of_on_demand_price ⇒ Float The bid price, as a percentage of On-Demand price, for each EC2 Spot instance as defined by InstanceType.
#configurations ⇒ Array<Types::Configuration> A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software that run on the cluster.
#ebs_configuration ⇒ Types::EbsConfiguration The configuration of Amazon Elastic Block Storage (EBS) attached to each instance as defined by InstanceType.
#instance_type ⇒ String An EC2 instance type, such as m3.xlarge.
#weighted_capacity ⇒ Integer The number of units that a provisioned instance of this type provides toward fulfilling the target capacities defined in InstanceFleetConfig.

Instance Attribute Details #bid_price ⇒ String

The bid price for each EC2 Spot instance type as defined by InstanceType. Expressed in USD. If neither BidPrice nor BidPriceAsPercentageOfOnDemandPrice is provided, BidPriceAsPercentageOfOnDemandPrice defaults to 100%.

#bid_price_as_percentage_of_on_demand_price ⇒ Float

The bid price, as a percentage of On-Demand price, for each EC2 Spot instance as defined by InstanceType. Expressed as a number (for example, 20 specifies 20%). If neither BidPrice nor BidPriceAsPercentageOfOnDemandPrice is provided, BidPriceAsPercentageOfOnDemandPrice defaults to 100%.

#configurations ⇒ Array<Types::Configuration>

A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software that run on the cluster.

#ebs_configuration ⇒ Types::EbsConfiguration

The configuration of Amazon Elastic Block Storage (EBS) attached to each instance as defined by InstanceType.

#instance_type ⇒ String

An EC2 instance type, such as m3.xlarge.

#weighted_capacity ⇒ Integer

The number of units that a provisioned instance of this type provides toward fulfilling the target capacities defined in InstanceFleetConfig. This value is 1 for a master instance fleet, and must be 1 or greater for core and task instance fleets. Defaults to 1 if not specified.
