Vultr Terraform provides quick and efficient provision and management of Vultr resources. At Bobcares, as part of our Server Management Services, we handle your Terraform issues, large or small.

Vultr Terraform

Terraform can interact with a cloud service provider by managing the cloud resources accessible through a provider plugin. The Vultr provider plugin enables the creation, modification, and destruction of infrastructure components such as load balancers, bare metal servers, and cloud instances.

Building The Vultr Terraform Provider

In order to build the provider, Our Support team suggests the following steps.

1. Firstly, clone the repository to $GOPATH/src/github.com/vultr/terraform-provider-vultr.

   $ mkdir -p $GOPATH/src/github.com/vultr; cd $GOPATH/src/github.com/vultr
   $ git clone git@github.com:vultr/terraform-provider-vultr.git
2. Then create the provider by entering the provider directory.

   $ cd $GOPATH/src/github.com/vultr/terraform-provider-vultr
   $ make build

Developing the Vultr Terraform Provider

We can follow the below steps to develop the Vultr Terraform provider.

1. Firstly, to work on the provider, we need Go installed on the machine. Then correctly set up a GOPATH and add $GOPATH/bin to the $PATH.
2. Run make build to compile the provider. By doing this, the provider will be built and its binary added to the $GOPATH/bin directory.

   $ make build
   ...
   $ $GOPATH/bin/terraform-provider-vultr
   ...
3. We can just run the below code to test the provider.

   $ make test
4. Run make testacc to execute the complete set of acceptance tests.

   $ make testacc
5. Finally, use the TESTARGS environment variable to run a specific acceptance test.

   $ make testacc TESTARGS='-run=TestAccVultrUser_base'

   The above code will only run the TestAccVultrUser base acceptance test.

Vultr Provider Usage

To interact with the resources that Vultr supports, use the Vultr provider. We must use the correct credentials to configure the provider before its use. For instance, consider the following code for Vultr Terraform.

terraform {
  required_providers {
    vultr = {
      source = "vultr/vultr"
      version = "2.11.3"
    }
  }
}

# Configure the Vultr Provider
provider "vultr" {
  api_key = "VULTR_API_KEY"
  rate_limit = 700
  retry_limit = 3
}

# Create a web instance
resource "vultr_instance" "web" {
  # ...
}

The api_key is the Vultr API key. The shell environment variable VULTR_API_KEY can also specify this. The rate_limit and retry_limit are optional. Vultr limits API calls to 3 calls per second for rate_limit. The retry_limit lets us configure how many retries should be attempted on a failed call. The default value is 3 retries.
