Public IP Terraform Provider

This Terraform provider connects to ifconfig.co to fetch information about the public IP in use. It was mainly built to allow creating or adjusting firewall rules in cloud setups on the fly, so that other providers that connect directly to the resources can operate.

For example and at least until version 3, the azurerm provider needed to connect to the Azure Storage account directly to manage blob containers. Likewise, a postgresql provider needs to directly connect to the database to do its job.

Usage

terraform {
  required_providers {
    publicip = {
      source = "nxt-engineering/publicip"
      version = "~> 0.0.3"
    }
  }
}

provider "publicip" {}

data "publicip_address" "main" {}

output "ip" {
  value = data.publicip_address.main.ip
}

output "all" {
  value = data.publicip_address.main
}

Development

Requirements

• Terraform >= 1.0
• Go >= 1.17

Building The Provider

1. Clone the repository
2. Enter the repository directory
3. Build the provider using the Go install command:

go install

Testrun

Add this to your ~/.terraformrc:

provider_installation {
  dev_overrides {
    # Edit the path …                         … here:  |________|
    "registry.terraform.io/nxt-engineering/publicip" = "HOME/SRC/terraform-provider-publicip"
  }

  direct {}
}

Set up a dummy project like this:

terraform {
  required_providers {
    publicip = {
      source = "nxt-engineering/publicip"
    }
  }
}

provider "publicip" {}

data "publicip_address" "default" {}

data "publicip_address" "default_v4" {
  source_ip = "0.0.0.0"
}

data "publicip_address" "default_v6" {
  source_ip = "::"
}

output "out" {
  value = {
    default    = data.publicip_address.default,
    default_v4 = data.publicip_address.default_v4,
    default_v6 = data.publicip_address.default_v6,
  }
}

Build the provider:

go build -o terraform-provider-publicip

Run the provider like this:

TF_LOG_PROVIDER=DEBUG terraform apply -auto-approve
