--filters (list)

The filters.

  • group-name - The name of the placement group.
  • state - The state of the placement group (pending | available | deleting | deleted ).
  • strategy - The strategy of the placement group (cluster | spread | partition ).

Shorthand Syntax:

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

JSON Syntax:

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

--group-names (list)

The names of the placement groups.

Default: Describes all your placement groups, or only those otherwise specified.


"string" "string" ...

--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.
