    10  
    11  Provides an AWS EIP Association as a top level resource, to associate and
    12  disassociate Elastic IPs from AWS Instances and Network Interfaces.
    13  
    14  ~> **NOTE:** `aws_eip_association` is useful in scenarios where EIPs are either
    15  pre-existing or distributed to customers or users and therefore cannot be changed.
    16  
    17  ## Example Usage
    18  
    19  ```
    20  resource "aws_eip_association" "eip_assoc" {
    21    instance_id = "${aws_instance.web.id}"
    22    allocation_id = "${aws_eip.example.allocation_id}"
    23  }
    24  
    25  resource "aws_instance" "web" {
    26    ami = "ami-21f78e11"
    27    availability_zone = "us-west-2a"
    28    instance_type = "t1.micro"
    29    tags {
    30      Name = "HelloWorld"
    31    }
    32  }
    33  
    34  resource "aws_eip" "example" {
    35    vpc = true
    36  }
    37  ```

    39  ## Argument Reference
    40  
    41  The following arguments are supported:
    42  
    43  * `allocation_id` - (Optional) The allocation ID. This is required for EC2-VPC.
    44  * `allow_reassociation` - (Optional, Boolean) Whether to allow an Elastic IP to
    45  be re-associated. Defaults to `true` in VPC.
    46  * `instance_id` - (Optional) The ID of the instance. This is required for
    47  EC2-Classic. For EC2-VPC, you can specify either the instance ID or the
    48  network interface ID, but not both. The operation fails if you specify an
    49  instance ID unless exactly one network interface is attached. 
    50  * `network_interface_id` - (Optional) The ID of the network interface. If the
    51  instance has more than one network interface, you must specify a network
    52  interface ID.
    53  * `private_ip_address` - (Optional) The primary or secondary private IP address
    54  to associate with the Elastic IP address. If no private IP address is
    55  specified, the Elastic IP address is associated with the primary private IP
    56  address.
    57  * `public_ip` - (Optional) The Elastic IP address. This is required for EC2-Classic.
    58  
    59  ## Attributes Reference
    60  
    61  * `association_id` - The ID that represents the association of the Elastic IP
    62  address with an instance.
    63  * `allocation_id` - As above
    64  * `instance_id` - As above
    65  * `network_interface_id` - As above
    66  * `private_ip_address` - As above
    67  * `public_ip` - As above
