        )]
    )],
    tenancy="tenancy",
    unused_reservation_billing_owner_id="unusedReservationBillingOwnerId"
)

Parameters:

scope (Construct) – Scope in which this resource is defined.
id (str) – Construct identifier for this resource (unique in its scope).
availability_zone (str) – The Availability Zone in which to create the Capacity Reservation.
instance_count (Union[int, float]) – The number of instances for which to reserve capacity. .. epigraph:: You can request future-dated Capacity Reservations for an instance count with a minimum of 100 VPUs. For example, if you request a future-dated Capacity Reservation for m5.xlarge instances, you must request at least 25 instances ( 25 * m5.xlarge = 100 vCPUs ). Valid range: 1 - 1000
instance_platform (str) – The type of operating system for which to reserve capacity.
instance_type (str) – The instance type for which to reserve capacity. .. epigraph:: You can request future-dated Capacity Reservations for instance types in the C, M, R, I, and T instance families only. For more information, see Instance types in the Amazon EC2 User Guide .
ebs_optimized (Union[bool, IResolvable, None]) – Indicates whether the Capacity Reservation supports EBS-optimized instances. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal I/O performance. This optimization isn’t available with all instance types. Additional usage charges apply when using an EBS- optimized instance.
end_date (Optional[str]) – The date and time at which the Capacity Reservation expires. When a Capacity Reservation expires, the reserved capacity is released and you can no longer launch instances into it. The Capacity Reservation’s state changes to expired when it reaches its end date and time. You must provide an EndDate value if EndDateType is limited . Omit EndDate if EndDateType is unlimited . If the EndDateType is limited , the Capacity Reservation is cancelled within an hour from the specified time. For example, if you specify 5/31/2019, 13:30:55, the Capacity Reservation is guaranteed to end between 13:30:55 and 14:30:55 on 5/31/2019. If you are requesting a future-dated Capacity Reservation, you can’t specify an end date and time that is within the commitment duration.
end_date_type (Optional[str]) – Indicates the way in which the Capacity Reservation ends. A Capacity Reservation can have one of the following end types: - unlimited - The Capacity Reservation remains active until you explicitly cancel it. Do not provide an EndDate if the EndDateType is unlimited . - limited - The Capacity Reservation expires automatically at a specified date and time. You must provide an EndDate value if the EndDateType value is limited .
ephemeral_storage (Union[bool, IResolvable, None]) – Deprecated..
instance_match_criteria (Optional[str]) – Indicates the type of instance launches that the Capacity Reservation accepts. The options include:. - open - The Capacity Reservation automatically matches all instances that have matching attributes (instance type, platform, and Availability Zone). Instances that have matching attributes run in the Capacity Reservation automatically without specifying any additional parameters. - targeted - The Capacity Reservation only accepts instances that have matching attributes (instance type, platform, and Availability Zone), and explicitly target the Capacity Reservation. This ensures that only permitted instances can use the reserved capacity. .. epigraph:: If you are requesting a future-dated Capacity Reservation, you must specify targeted . Default: open
out_post_arn (Optional[str]) –

Not supported for future-dated Capacity Reservations. The Amazon Resource Name (ARN) of the Outpost on which to create the Capacity Reservation.
placement_group_arn (Optional[str]) –

Not supported for future-dated Capacity Reservations. The Amazon Resource Name (ARN) of the cluster placement group in which to create the Capacity Reservation. For more information, see Capacity Reservations for cluster placement groups in the Amazon EC2 User Guide .
tag_specifications (Union[IResolvable, Sequence[Union[IResolvable, TagSpecificationProperty, Dict[str, Any]]], None]) – The tags to apply to the Capacity Reservation during launch.
tenancy (Optional[str]) – Indicates the tenancy of the Capacity Reservation. A Capacity Reservation can have one of the following tenancy settings:. - default - The Capacity Reservation is created on hardware that is shared with other AWS accounts . - dedicated - The Capacity Reservation is created on single-tenant hardware that is dedicated to a single AWS account .
unused_reservation_billing_owner_id (Optional[str]) – The ID of the AWS account to which to assign billing of the unused capacity of the Capacity Reservation. A request will be sent to the specified account. That account must accept the request for the billing to be assigned to their account. For more information, see Billing assignment for shared Amazon EC2 Capacity Reservations . You can assign billing only for shared Capacity Reservations. To share a Capacity Reservation, you must add it to a resource share. For more information, see AWS::RAM::ResourceShare .

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_dependency(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_depends_on(target)

(deprecated) Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

Parameters:

target (CfnResource) –

Deprecated:

use addDependency

Stability:

deprecated

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

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 addPropertyOverride or prefix path with “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 value argument to addOverride will 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 intermediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

Parameters:

policy (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resource, please consult that specific resource’s documentation.

See:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options

Return type:

None

get_att(attribute_name, type_hint=None)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:

attribute_name (str) – The name of the attribute.
type_hint (Optional[ResolutionTypeHint]) –

Return type:

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Static Methods

classmethod is_cfn_element(x)

Returns true if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of instanceof to allow stack elements from different versions of this library to be included in the same stack.

Parameters:

x (Any) –

Return type:

bool

Returns:

The construct as a stack element or undefined if it is not a stack element.

classmethod is_cfn_resource(x)

Check whether the given object is a CfnResource.

Parameters:

x (Any) –

Return type:

bool

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.

TagSpecificationProperty

class CfnCapacityReservation.TagSpecificationProperty(*, resource_type=None, tags=None)

Bases: object

An array of key-value pairs to apply to this resource.

For more information, see Tag .

Parameters:

resource_type (Optional[str]) – The type of resource to tag. Specify capacity-reservation .
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – The tags to apply to the resource.
