- class aws_cdk.aws_ec2.CfnEC2Fleet(scope, id, *, launch_template_configs, target_capacity_specification, context=None, excess_capacity_termination_policy=None, on_demand_options=None, replace_unhealthy_instances=None, spot_options=None, tag_specifications=None, terminate_instances_with_expiration=None, type=None, valid_from=None, valid_until=None)
- Bases: - CfnResource- A CloudFormation - AWS::EC2::EC2Fleet.- Specifies the configuration information to launch a fleet–or group–of instances. An EC2 Fleet can launch multiple instance types across multiple Availability Zones, using the On-Demand Instance, Reserved Instance, and Spot Instance purchasing models together. Using EC2 Fleet, you can define separate On-Demand and Spot capacity targets, specify the instance types that work best for your applications, and specify how Amazon EC2 should distribute your fleet capacity within each purchasing model.

- path ( - str) – The path of the value to delete.
- Return type:
- None
 
 - add_depends_on(target)
- Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned. - This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope. - Parameters:
- target ( - CfnResource)
- Return type:
- None
 
 - add_metadata(key, value)
- Add a value to the CloudFormation Resource Metadata. - Parameters:
- key ( - str)
- value ( - Any)
 
- See:
- Return type:
- None
 - Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly. 
 - add_override(path, value)
- Adds an override to the synthesized CloudFormation resource. - To add a property override, either use - addPropertyOverrideor prefix- pathwith “Properties.” (i.e.- Properties.TopicName).- If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path. - To include a literal - .in the property name, prefix with a- \. In most programming languages you will need to write this as- "\\."because the- \itself will need to be escaped.- For example: - cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"]) cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE") - would add the overrides Example: - "Properties": { "GlobalSecondaryIndexes": [ { "Projection": { "NonKeyAttributes": [ "myattribute" ] ... } ... }, { "ProjectionType": "INCLUDE" ... }, ] ... } - The - valueargument to- addOverridewill not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.- Parameters:
- path ( - str) –- The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed. 
 
- value ( - Any) –- The value. Could be primitive or complex.

- class CfnEC2Fleet.FleetLaunchTemplateOverridesRequestProperty(*, availability_zone=None, instance_requirements=None, instance_type=None, max_price=None, placement=None, priority=None, subnet_id=None, weighted_capacity=None)
- Bases: - object- Specifies overrides for a launch template for an EC2 Fleet. - FleetLaunchTemplateOverridesRequestis a property of the FleetLaunchTemplateConfigRequest property type.- Parameters:
- availability_zone ( - Optional[- str]) – The Availability Zone in which to launch the instances.
- instance_requirements ( - Union[- IResolvable,- InstanceRequirementsRequestProperty,- Dict[- str,- Any],- None]) – The attributes for the instance types. When you specify instance attributes, Amazon EC2 will identify instance types with those attributes. .. epigraph:: If you specify- InstanceRequirements, you can’t specify- InstanceType.
- instance_type ( - Optional[- str]) – The instance type.- mac1.metalis not supported as a launch template override. .. epigraph:: If you specify- InstanceType, you can’t specify- InstanceRequirements.
- max_price ( - Optional[- str]) – 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. .. epigraph:: If you specify a maximum price, your instances will be interrupted more frequently than if you do not specify this parameter.
- placement ( - Union[- IResolvable,- PlacementProperty,- Dict[- str,- Any],- None]) – The location where the instance launched, if applicable.
- priority ( - Union[- int,- float,- None]) – The priority for the launch template override. The highest priority is launched first. If the On-Demand- AllocationStrategyis set to- prioritized, EC2 Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity. If the Spot- AllocationStrategyis 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.
- subnet_id ( - Optional[- str]) – 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- instantcan have only one subnet ID.
- weighted_capacity ( - Union[- int,- float,- None]) – The number of units provided by the specified instance type.

- Bases: - object- Specifies the configuration of Spot Instances for an EC2 Fleet. - SpotOptionsRequestis a property of the AWS::EC2::EC2Fleet resource.- Parameters:
- allocation_strategy ( - Optional[- str]) – Indicates how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the EC2 Fleet. If the allocation strategy is- lowestPrice, EC2 Fleet launches instances from the Spot Instance pools with the lowest price. This is the default allocation strategy. If the allocation strategy is- diversified, EC2 Fleet launches instances from all the Spot Instance pools that you specify. If the allocation strategy is- capacityOptimized, EC2 Fleet launches instances from Spot Instance pools that are optimally chosen based on the available Spot Instance capacity. Allowed Values :- lowestPrice|- diversified|- capacityOptimized|- capacityOptimizedPrioritized

If a pool runs out of Spot capacity before fulfilling your target capacity, EC2 Fleet will continue to fulfill your request by drawing from the next cheapest pool. To ensure that your target capacity is met, you might receive Spot Instances from more than the number of pools that you specified. Similarly, if most of the pools have no Spot capacity, you might receive your full target capacity from fewer than the number of pools that you specified.
- maintenance_strategies ( - Union[- IResolvable,- MaintenanceStrategiesProperty,- Dict[- str,- Any],- None]) – The strategies for managing your Spot Instances that are at an elevated risk of being interrupted.
- max_total_price ( - Optional[- str]) – The maximum amount per hour for Spot Instances that you’re willing to pay. 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. .. epigraph:: If you specify a maximum price, your Spot Instances will be interrupted more frequently than if you do not specify this parameter.
- min_target_capacity ( - Union[- int,- float,- None]) – The minimum target capacity for Spot Instances in the fleet. If the minimum target capacity is not reached, the fleet launches no instances. Supported only for fleets of type- instant. At least one of the following must be specified:- SingleAvailabilityZone|- SingleInstanceType
- single_availability_zone ( - Union[- bool,- IResolvable,- None]) – Indicates that the fleet launches all Spot Instances into a single Availability Zone. Supported only for fleets of type- instant.
