     9  # aws\_eip\_association
    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  ```hcl
    20  resource "aws_eip_association" "eip_assoc" {
    21    instance_id   = "${aws_instance.web.id}"
    22    allocation_id = "${aws_eip.example.id}"
    23  }
    24  
    25  resource "aws_instance" "web" {
    26    ami               = "ami-21f78e11"
    27    availability_zone = "us-west-2a"
    28    instance_type     = "t1.micro"
    29  
    30    tags {
    31      Name = "HelloWorld"
    32    }
    33  }
    34  
    35  resource "aws_eip" "example" {
    36    vpc = true
    37  }
    38  ```

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