Namecheap Terraform Provider

A Terraform Provider for Namecheap domain dns configuration.

Prerequisites

First you'll need to apply for API access to Namecheap. You can do that on this API admin page.

Next, find out your IP address and add that IP (or any other IPs accessing this API) to this whitelist admin page on Namecheap.

Once you've done that, make note of the API token, your IP address, and your username to fill into our provider block.

Usage

Then inside a Terraform file within your project (Ex. providers.tf):

Using the provider

Make sure your API details are correct in the provider block.

terraform {
  required_providers {
    namecheap = {
      source  = "robgmills/namecheap"
      version = "1.7.0"
    }
  }
}

provider "namecheap" {
  username = "your_username" # Also set by env variable `NAMECHEAP_USERNAME`
  api_user = "your_username" # Same as username; also set by env variable `NAMECHEAP_API_USER`
  token = "your_token" # Also set by env variable `NAMECHEAP_TOKEN`
  ip = "your.ip.address.here" # Also set by env variable `NAMECHEAP_IP`
  use_sandbox = false # Toggle for testing/sandbox mode; Also set by env variable `NAMECHEAP_USE_SANDBOX`
}

# Create a DNS A Record for a domain you own
resource "namecheap_record" "www-example-com" {
  name = "www"
  domain = "example.com"
  address = "127.0.0.1"
  mx_pref = 10
  type = "A"
}

Setup terraform and view the plan output.

$ terraform init
Terraform has been successfully initialized!

$ terraform plan
Terraform will perform the following actions:

  + namecheap_record.www-example.com
      id:       <computed>
      address:  "127.0.0.1"
      domain:   "example.com"
      hostname: <computed>
      mx_pref:  "10"
      name:     "www"
      ttl:      "60"
      type:     "A"


Plan: 1 to add, 0 to change, 0 to destroy.

$ terraform apply
...
Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

Building The Provider

$ go get github.com/adamdecaf/terraform-provider-namecheap
$ cd $GOPATH/src/github.com/adamdecaf/terraform-provider-namecheap
$ make build

Developing the Provider

If you wish to work on the provider, you'll first need Go installed on your machine (version 1.15+ is recommended). You'll also need to correctly setup a GOPATH, as well as adding $GOPATH/bin to your $PATH.

This project uses Go Modules, added in Go 1.11.

To compile the provider, run make build. This will build the provider and put the provider binary in the $GOPATH/bin directory.

$ make build
$ ls $GOPATH/bin/terraform-provider-namecheap
...

In order to test the provider, you can simply run make test.

$ make test

In order to run the full suite of Acceptance tests, run make testacc.

Note: Acceptance tests create real resources, and often cost money to run. They are also dependent on environment variables to configure the test instance of the provider.

$ make testacc

To contribute changes, please open a PR by forking the repository, adding the fork to your local copy of the git repository, create a branch, commit your changes, and open a PR:

$ git remote add fork git@github.com/youruser/terraform-provider-namechep
$ git checkout -b your-new-feature
$ git add .
$ git commit -m "Add a new feature"
$ git push -u fork your-new-feature
...

Troubleshooting the Provider

Problem: Error: Failed to create namecheap Record: Could not find the record with hash Solution: Double check your IP did not change and make sure it is whitelisted with Namecheaps API. Also ensure the domain names you have in your terraform config are still associated with your account (in cases like where you let one expire). In these rare edge-cases, you may have to delete the bad domain records by running terraform state rm namecheap_record.the_tf_name_of_your_record.
