Description

Creates a new Capacity Reservation with the specified attributes. Capacity Reservations enable you to reserve capacity for your Amazon EC2 instances in a specific Availability Zone for any duration. This gives you the flexibility to selectively add capacity reservations and still get the Regional RI discounts for that usage. By creating Capacity Reservations, you ensure that you always have access to Amazon EC2 capacity when you need it, for as long as you need it. For more information, see Capacity Reservations in the Amazon Elastic Compute Cloud User Guide. Your request to create a Capacity Reservation could fail if Amazon EC2 does not have sufficient capacity to fulfill the request. If your request fails due to Amazon EC2 capacity constraints, either try again at a later time, try in a different Availability Zone, or request a smaller capacity reservation. If your application is flexible across instance types and sizes, try to create a Capacity Reservation with different instance attributes. Your request could also fail if the requested quantity exceeds your On-Demand Instance limit for the selected instance type. If your request fails due to limit constraints, increase your On-Demand Instance limit for the required instance type and try again. For more information about increasing your instance limits, see Amazon EC2 Service Limits in the Amazon Elastic Compute Cloud User Guide.

Parameters

-AvailabilityZone <String>
The Availability Zone in which to create the Capacity Reservation.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-AvailabilityZoneId <String>
The service has not provided documentation for this parameter; please refer to the service's API reference documentation for the latest available information.
Required?False
Position?Named
Accept pipeline input?False
-ClientToken <String>
Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see How to Ensure Idempotency.Constraint: Maximum 64 ASCII characters.
Required?False
Position?Named
Accept pipeline input?False
-EbsOptimized <Boolean>
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.
Required?False
Position?Named
Accept pipeline input?False
-EndDate <DateTime>
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.
Required?False
Position?Named
Accept pipeline input?False
-EndDateType <EndDateType>
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.
Required?False
Position?Named
Accept pipeline input?False
-EphemeralStorage <Boolean>
Indicates whether the Capacity Reservation supports instances with temporary, block-level storage.
Required?False
Position?Named
Accept pipeline input?False
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?False
-InstanceCount <Int32>
The number of instances for which to reserve capacity.
Required?False
Position?Named
Accept pipeline input?False
-InstanceMatchCriterion <InstanceMatchCriteria>
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.
Default: open
Required?False
Position?Named
Accept pipeline input?False
AliasesInstanceMatchCriteria
The type of operating system for which to reserve capacity.
Required?False
Position?Named
Accept pipeline input?False
-InstanceType <String>
The instance type for which to reserve capacity. For more information, see Instance Types in the Amazon Elastic Compute Cloud User Guide.
Required?False
Position?1
Accept pipeline input?True (ByValue, )
-TagSpecification <TagSpecification[]>
The tags to apply to the Capacity Reservation during launch.
Required?False
Position?Named
Accept pipeline input?False
AliasesTagSpecifications
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.
Required?False
Position?Named
Accept pipeline input?False

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

You can pipe a String object to this cmdlet for the InstanceType parameter.

Outputs

This cmdlet returns a Amazon.EC2.Model.CapacityReservation object. The service call response (type Amazon.EC2.Model.CreateCapacityReservationResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
