See LICENSE for full details. Here you’ll specify the resource that you’re going to use, in this case: droplet. Terraform is an infrastructure as code tool created by HashiCorp that helps developers with deploying, updating, and removing different assets of their infrastructure in an efficient and more scalable way. To accomplish this, we’ll be using Terraform - an open source tool that codifies APIs into declarative configuration files. These rules replicate the state of the existing example firewall. Not only does load balancing enable your application servers to handle the usage more evenly, but they can also work as the edge of your cloud network and secure it using a firewall. After you import your Droplet and firewall into Terraform state, you need to make sure that configurations represent the current state of the imported assets. Tracking those changes and applying them by hand in the DigitalOcean control panel can be tedious. The terraform plan command is used as a dry run. You get paid; we donate to tech nonprofits. Supporting each other to make an impact. In this tutorial you’ll import existing DigitalOcean infrastructure into Terraform. tags - The names of the Tags assigned to the Firewall. This command will look for the same file terraform_0.12.12_SHA256SUMS locally and then check that the hashes match by using the -c flag. Note: You can include firewall resources in the digitalocean_droplet.tf file as well, however if you have multiple environments where multiple Droplets share the same firewall, it’s a good idea to separate it in case you only want to remove a single Droplet. Terraform is a tool developed by Hashicorp that allows you to define your server and cloud infrastructure using configuration. Contribute to Open Source. Since this file has more than one filename and its platform listed, you use the --ignore-missing flag to avoid errors in your output because you don’t have a copy of the other files. Once the Terraform configuration is up and running, just run terraform plan to see what's going to happen: $ terraform plan provider.digitalocean.token The token key for API operations. You’ll then check the import configuration with the terraform show and terraform plan commands. Terraform works with a long list of service providers (e.g. If an attacker knows the IP address of your origin server, this can easily be circumvented. This can also be achieved at the web server level using the DenyAllButCloudFlare rule from Cloudflare’s Mod_Cloudflare Apache extension or similar tools for Nginx. After you’ve updated your Terraform files, you’ll use the plan command to see if changes you made replicate state of existing assets on DigitalOcean. You can use it to manage DigitalOcean Droplets, Load Balancers, and even DNS entries, in addition to a large variety of services offered by other providers. Why would I use this? Example Usage Terraform is a great tool for automating infrastructure management. You can use the following guide on, A DigitalOcean Cloud Firewall applied to your Droplet. Now check if Terraform is installed properly by checking the version: You’ll see output similar to the following: You’ve installed Terraform to your local machine, you’ll now prepare the configuration files.
