» Data Source: aws_eip

aws_eip provides details about a specific Elastic IP.

This resource can prove useful when a module accepts an allocation ID or public IP as an input variable and needs to determine the other.

» Example Usage

The following example shows how one might accept a public IP as a variable and use this data source to obtain the allocation ID.

variable "instance_id" {}
variable "public_ip" {}

data "aws_eip" "proxy_ip" {
  public_ip = "${var.public_ip}"
}

resource "aws_eip_association" "proxy_eip" {
  instance_id   = "${var.instance_id}"
  allocation_id = "${data.aws_eip.proxy_ip.id}"
}

» Argument Reference

The arguments of this data source act as filters for querying the available Elastic IPs in the current region. The given filters must match exactly one Elastic IP whose data will be exported as attributes.

  • id - (Optional) The allocation id of the specific EIP to retrieve.

  • public_ip - (Optional) The public IP of the specific EIP to retrieve.

» Attributes Reference

All of the argument attributes are also exported as result attributes. This data source will complete the data by populating any fields that are not included in the configuration with the data for the selected Elastic IP.
