-MaxResult <Int32>
-NextToken <String>
-Select <String>
-NoAutoIteration <SwitchParameter>
-ClientConfig <AmazonEC2Config>

Description

Describes one or more of your Capacity Reservations. The results describe only the Capacity Reservations in the Amazon Web Services Region that you're currently using.

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-CapacityReservationId <String[]>
The ID of the Capacity Reservation.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesCapacityReservationIds
-ClientConfig <AmazonEC2Config>
Amazon.PowerShell.Cmdlets.EC2.AmazonEC2ClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Filter <Filter[]>
One or more filters.
  • instance-type - The type of instance for which the Capacity Reservation reserves capacity.
  • owner-id - The ID of the Amazon Web Services account that owns the Capacity Reservation.
  • instance-platform - The type of operating system for which the Capacity Reservation reserves capacity.
  • availability-zone - The Availability Zone of the Capacity Reservation.
  • tenancy - 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 Amazon Web Services accounts.
    • dedicated - The Capacity Reservation is created on single-tenant hardware that is dedicated to a single Amazon Web Services account.
  • outpost-arn - The Amazon Resource Name (ARN) of the Outpost on which the Capacity Reservation was created.
  • state - The current state of the Capacity Reservation. A Capacity Reservation can be in one of the following states:
    • active- The Capacity Reservation is active and the capacity is available for your use.
    • expired - The Capacity Reservation expired automatically at the date and time specified in your request. The reserved capacity is no longer available for your use.
    • cancelled - The Capacity Reservation was cancelled. The reserved capacity is no longer available for your use.
    • pending - The Capacity Reservation request was successful but the capacity provisioning is still pending.
    • failed - The Capacity Reservation request has failed. A request might fail due to invalid request parameters, capacity constraints, or instance limit constraints. Failed requests are retained for 60 minutes.
  • start-date - The date and time at which the Capacity Reservation was started.
  • end-date - 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.
  • end-date-type - 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.
    • limited - The Capacity Reservation expires automatically at a specified date and time.
  • instance-match-criteria - Indicates the type of instance launches that the Capacity Reservation accepts. The options include:
    • open - The Capacity Reservation accepts all instances that have matching attributes (instance type, platform, and Availability Zone). Instances that have matching attributes launch into 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.
  • placement-group-arn - The ARN of the cluster placement group in which the Capacity Reservation was created.
Required?False
Position?Named

AliasesFilters
-MaxResult <Int32>
The maximum number of items to return for this request. To get the next page of items, make another request with the token returned in the output. For more information, see Pagination.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxResults
-NextToken <String>
The token to use to retrieve the next page of results.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-NextToken $null' for the first call and '-NextToken $AWSHistory.LastServiceResponse.NextToken' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'CapacityReservations'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.DescribeCapacityReservationsResponse). Specifying the name of a property of type Amazon.EC2.Model.DescribeCapacityReservationsResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

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?True (ByPropertyName)
AliasesAK
-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?True (ByValue, ByPropertyName)
-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?True (ByPropertyName)
-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?True (ByValue, ByPropertyName)
-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.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?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information.
