Description

Modifies the Capacity Reservation settings for a stopped instance. Use this action to configure an instance to target a specific Capacity Reservation, run in any open Capacity Reservation with matching attributes, run in On-Demand Instance capacity, or only run in a Capacity Reservation.

Options

--instance-id (string)

The ID of the instance to be modified.

--capacity-reservation-specification (structure)

Information about the Capacity Reservation targeting option.

CapacityReservationPreference -> (string)

Indicates the instance’s Capacity Reservation preferences. Possible preferences include:

• capacity-reservations-only - The instance will only run in a Capacity Reservation or Capacity Reservation group. If capacity isn’t available, the instance will fail to launch.
• open - The instance can run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone, and tenancy). If capacity isn’t available, the instance runs as an On-Demand Instance.
• none - The instance doesn’t run in a Capacity Reservation even if one is available. The instance runs as an On-Demand Instance.

CapacityReservationTarget -> (structure)

Information about the target Capacity Reservation or Capacity Reservation group.

CapacityReservationId -> (string)

The ID of the Capacity Reservation in which to run the instance.

CapacityReservationResourceGroupArn -> (string)

The ARN of the Capacity Reservation resource group in which to run the instance.

Shorthand Syntax:

CapacityReservationPreference=string,CapacityReservationTarget={CapacityReservationId=string,CapacityReservationResourceGroupArn=string}

JSON Syntax:

{
  "CapacityReservationPreference": "capacity-reservations-only"|"open"|"none",
  "CapacityReservationTarget": {
    "CapacityReservationId": "string",
    "CapacityReservationResourceGroupArn": "string"
  }
}

--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 .

--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. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--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)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To modify an instance’s capacity reservation targeting settings

The following modify-instance-capacity-reservation-attributes example modifies a stopped instance to target a specific capacity reservation.

aws ec2 modify-instance-capacity-reservation-attributes \
    --instance-id i-EXAMPLE8765abcd4e \
    --capacity-reservation-specification 'CapacityReservationTarget={CapacityReservationId= cr-1234abcd56EXAMPLE }'

Output:

{
    "Return": true
}

Example 2: To modify an instance’s capacity reservation targeting settings

The following modify-instance-capacity-reservation-attributes example modifies a stopped instance that targets the specified capacity reservation to launch in any capacity reservation that has matching attributes (instance type, platform, Availability Zone) and that has open instance matching criteria.

aws ec2 modify-instance-capacity-reservation-attributes \
    --instance-id i-EXAMPLE8765abcd4e \
    --capacity-reservation-specification 'CapacityReservationPreference=open'

Output:

{
    "Return": true
}

For more information, see Modifying an Instance’s Capacity Reservation Settings in the Amazon Elastic Compute Cloud User Guide for Linux Instances.

Output

Return -> (boolean)

Returns true if the request succeeds; otherwise, it returns an error.
