AWS CLI Command Reference

[ aws . ec2 ]

create-capacity-reservation

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.

You can create a Capacity Reservation at any time, and you can choose when it starts. You can create a Capacity Reservation for immediate use or you can request a Capacity Reservation for a future date.

For more information, see Reserve compute capacity with On-Demand Capacity Reservations in the Amazon EC2 User Guide .

Your request to create a Capacity Reservation could fail if:

  • Amazon EC2 does not have sufficient capacity. In this case, try again at a later time, try in a different Availability Zone, or request a smaller Capacity Reservation. If your workload is flexible across instance types and sizes, try with different instance attributes.
  • The requested quantity exceeds your On-Demand Instance quota. In this case, increase your On-Demand Instance quota for the requested instance type and try again. For more information, see Amazon EC2 Service Quotas in the Amazon EC2 User Guide .

Options

--client-token (string)

Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see Ensure Idempotency .

--instance-type (string) [required]

The instance type for which to reserve capacity.

Note

You can request future-dated Capacity Reservations for instance types in the C, M, R, I, T, and G instance families only.

For more information, see Instance types in the Amazon EC2 User Guide .

--instance-platform (string) [required]

The type of operating system for which to reserve capacity.

Possible values:

  • Linux/UNIX
  • Red Hat Enterprise Linux
  • SUSE Linux
  • Windows
  • Windows with SQL Server
  • Windows with SQL Server Enterprise
  • Windows with SQL Server Standard
  • Windows with SQL Server Web
  • Linux with SQL Server Standard
  • Linux with SQL Server Web
  • Linux with SQL Server Enterprise
  • RHEL with SQL Server Standard
  • RHEL with SQL Server Enterprise
  • RHEL with SQL Server Web
  • RHEL with HA
  • RHEL with HA and SQL Server Standard
  • RHEL with HA and SQL Server Enterprise
  • Ubuntu Pro

--availability-zone (string)

The Availability Zone in which to create the Capacity Reservation.

--availability-zone-id (string)

The ID of the Availability Zone in which to create the Capacity Reservation.

--tenancy (string)

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.

Possible values:

  • default
  • dedicated

--instance-count (integer) [required]

The number of instances for which to reserve capacity.

Note

You can request future-dated Capacity Reservations for an instance count with a minimum of 32 vCPUs. For example, if you request a future-dated Capacity Reservation for m5.xlarge instances, you must request at least 8 instances (8 * m5.xlarge = 32 vCPUs ).

Valid range: 1 - 1000

--ebs-optimized | --no-ebs-optimized (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.

--ephemeral-storage | --no-ephemeral-storage (boolean)

Deprecated.

--end-date (timestamp)

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 (string)

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 .

Possible values:

  • unlimited
  • limited

--instance-match-criteria (string)

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.

Note

If you are requesting a future-dated Capacity Reservation, you must specify targeted .

Default: open

Possible values:

  • open
  • targeted

--tag-specifications (list)

The tags to apply to the Capacity Reservation during launch.

(structure)

The tags to apply to a resource when the resource is being created. When you specify a tag, you must specify the resource type to tag, otherwise the request will fail.

Note

The Valid Values lists all the resource types that can be tagged. However, the action you’re using might not support tagging all of these resource types. If you try to tag a resource type that is unsupported for the action you’re using, you’ll get an error.

ResourceType -> (string)

The type of resource to tag on creation.

  • capacity-reservation
  • client-vpn-endpoint
