     9  # random\_shuffle
    10  
    11  The resource `random_shuffle` generates a random permutation of a list
    12  of strings given as an argument.
    13  
    14  ## Example Usage
    15  
    16  ```
    17  resource "random_shuffle" "az" {
    18    input = ["us-west-1a", "us-west-1c", "us-west-1d", "us-west-1e"]
    19    result_count = 2
    20  }
    21  
    22  resource "aws_elb" "example" {
    23    # Place the ELB in any two of the given availability zones, selected
    24    # at random.
    25    availability_zones = ["${random_shuffle.az.result}"]
    26  
    27    # ... and other aws_elb arguments ...
    28  }
    29  ```
    30  
    31  ## Argument Reference
    32  
    33  The following arguments are supported:
    34  
    35  * `input` - (Required) The list of strings to shuffle.
    36  
    37  * `result_count` - (Optional) The number of results to return. Defaults to
    38    the number of items in the `input` list. If fewer items are requested,
    39    some elements will be excluded from the result. If more items are requested,
    40    items will be repeated in the result but not more frequently than the number
    41    of items in the input list.
    42  
    43  * `keepers` - (Optional) Arbitrary map of values that, when changed, will
    44    trigger a new id to be generated. See
    45    [the main provider documentation](../index.html) for more information.
    46  
    47  * `seed` - (Optional) Arbitrary string with which to seed the random number
    48    generator, in order to produce less-volatile permutations of the list.
    49    **Important:** Even with an identical seed, it is not guaranteed that the
    50    same permutation will be produced across different versions of Terraform.
    51    This argument causes the result to be *less volatile*, but not fixed for
    52    all time.
    53  
    54  ## Attributes Reference

    56  The following attributes are exported:
    57  
    58  * `result` - Random permutation of the list of strings given in `input`.
