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. 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 EC2 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 Quotas in the Amazon EC2 User Guide .

--instance-count (integer)

The number of instances for which to reserve capacity.

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.

--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.

Default: open

Possible values:

  • open

  • targeted

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--outpost-arn (string)

The Amazon Resource Name (ARN) of the Outpost on which to create the Capacity Reservation.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json

  • text

  • table

  • yaml

  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on

  • off

  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64

  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Example 2: To create a Capacity Reservation that automatically ends at a specified date/time

The following create-capacity-reservation example creates a capacity reservation in the eu-west-1a Availability Zone, into which you can launch three m5.large instances running a Linux/Unix operating system. This capacity reservation automatically ends on 08/31/2019 at 23:59:59.

aws ec2 create-capacity-reservation \
    --availability-zone eu-west-1a \
    --instance-type m5.large \
    --instance-platform Linux/UNIX \
    --instance-count 3 \
    --end-date-type limited \
    --end-date 2019-08-31T23:59:59Z

Output:

{
    "CapacityReservation": {
        "CapacityReservationId": "cr-1234abcd56EXAMPLE ",
        "EndDateType": "limited",

        "InstanceType": "m5.large"
    }
}

Example 3: To create a Capacity Reservation that accepts only targeted instance launches

The following create-capacity-reservation example creates a capacity reservation that accepts only targeted instance launches.

aws ec2 create-capacity-reservation \
    --availability-zone eu-west-1a \
    --instance-type m5.large \
    --instance-platform Linux/UNIX \
    --instance-count 3 \
    --instance-match-criteria targeted

Output:

{
    "CapacityReservation": {
        "CapacityReservationId": "cr-1234abcd56EXAMPLE ",
        "EndDateType": "unlimited",
        "AvailabilityZone": "eu-west-1a",
