--filter (list)

One or more filters.

  • instance-family - The instance family (for example, m4 ).
  • payment-option - The payment option (NoUpfront | PartialUpfront | AllUpfront ).
  • state - The state of the reservation (payment-pending | payment-failed | active | retired ).

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

    "Name": "string",
    "Values": ["string", ...]

--host-reservation-id-set (list)

One or more host reservation IDs.


"string" "string" ...

--max-results (integer)

The maximum number of results to return for the request in a single page. The remaining results can be seen by sending another request with the returned nextToken value. This value can be between 5 and 500. If maxResults is given a larger value than 500, you receive an error.

--next-token (string)

The token to use to retrieve the next page of results.

--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.

See 'aws help' for descriptions of global parameters.
