--reserved-instances-offering-id (string)

The ID of the Reserved Instance offering to purchase.

--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 .

--limit-price (structure)

Specified for Reserved Instance Marketplace offerings to limit the total order and ensure that the Reserved Instances are not purchased at unexpected prices.

Amount -> (double)

Used for Reserved Instance Marketplace offerings. Specifies the limit price on the total order (instanceCount * price).

CurrencyCode -> (string)

The currency in which the limitPrice amount is specified. At this time, the only supported currency is USD .

}

--purchase-time (timestamp)

The time at which to purchase the Reserved Instance, in UTC format (for example, YYYY -MM -DD T*HH* :MM :SS Z).

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
