Now that our Terraform configuration is ready, let us deploy the droplet by running the following code. For example, if you need a brand-new development environment, and you have it previously mapped out in a Terraform configuration using a simple deployment command, you can have a brand-new development environment ready to go. Within the digitalocean.tfvars, we will create a simple variable named api_token. As we want to create two web servers with the same specs we use the count statement in Terraform to create both of them without repeating the same code. If you need a quickly provisioned computing environment, DigitalOcean virtual machines typically become available in under 60 seconds. I have been trying to dynamically create the Terraform code for a managed Digital Ocean database I have. Now the only remaining resources are the three Firewalls: As with the previous example, we have to run terraform init to initialize and then terraform apply to create the resources. In this first example, we are going to use the DigitalOcean provider available in Terraform to create the following infrastructure. And then we will see in DigitalOcean that everything has been created successfully. If we want to destroy these resources we just have to run terraform destroy. To get this token, you can follow their instructions about How to Create a Personal Access Token. Try running "terraform plan" to see any changes that are required for your infrastructure. A Droplet to be used as a web server A Firewall to allow only incoming SSH and HTTP (s) traffic to the Droplet. You can do it following their instructions about How to Upload SSH Public Keys to a DigitalOcean Account. * provider.digitalocean: version = "~> 0.1" Terraform has been successfully initialized! ; A DigitalOcean API access token. A Load Balancer to evenly distribute the incoming HTTP traffic across the web servers. Using this configuration as code, you can provision entire environments quickly and easily within DigitalOcean using Terraform. To allow our configuration to use the provider and credentials, we need to tell it where to get that data. For Terraform to communicate with DigitalOcean, we need to generate API Keys for use with the DigitalOcean provider. Terraform, Packer) gives you an exit strategy for free. The next step would be to create a DigitalOcean Read Write Token for Terraform to use when connecting to the DigitalOcean api. Using an environment variable keeps the token out of config files, so secrets are not accidentally committed to the git repository and published. There you will find other interesting resources like Domains, Droplet Snapshots, Projects, DNS Records, Spaces Buckets, Volumes, and much more! Join 5,000 subscribers and get a periodic digest of news, articles, and more. Rename the terraform.tfvars.example file to terraform.tfvars. Once you have the token you need to export it as an environment variable with the following command: Every environment variable you export with the format TF_VAR_xyz will be available inside Terraform as xyz. There a many ways one could achieve this, but in this blog post I'll use Kubernetes external-dns. Example Usage # Set the variable value in *.tfvars file # or using -var="do_token=..." CLI option variable "do_token" {} # Configure the DigitalOcean Provider provider "digitalocean" {token = var.do_token } # Create a web server resource "digitalocean_droplet" "web" {# ...} Argument Reference. However, you can also retrieve these at any time using the Terraform command. In this section, we will see how Terraform can be used to provision a droplet on DigitalOcean. Example terraform config for creating a digitalocean droplet with volume. In this file we have defined the following variables, Now that we have seen the variables is time to see the file that defines the infrastructure resources: main.tf. First, create a directory to house our Terraform configuration. In this post, you will find a tutorial about getting started with Terraform and DigitalOcean.
