Copy CDN resources via Terraform

Terraform simplifies the duplication of CDN configurations across environments, ensuring consistency and reliability. By managing environment-specific variables and using workspaces, you can maintain identical setups across your staging and production environments.

To proceed with the following steps, you need to have API keys configured.

Step 1: Define variables

One of the key benefits of Terraform is its ability to manage configurations through variables, making it easier to handle environment-specific settings.

Create a variables.tf file to define parameters that change between environments, such as API URL, token, or CDN resource names.

// variables.tf variable "api_token" { description = "API token for access to your Gcore account" type = string sensitive = true } variable "api_endpoint" { description = "Gcore API url" type = string } variable "cdn_resource_cname" { description = "Name of the CDN resource" type = string }

Step 2: Configure environment variables

Create .tfvars file for each environment to set the variable values. For example, for preproduction:

// preprod.tfvars api_token = "your-preprod-api-token" api_endpoint = "https://api.preprod.world" cdn_resource_cname = "preprod.example.com"

And for production:

// production.tfvars api_token = "your-production-api-token" api_endpoint = "https://api.gcore.com" cdn_resource_cname = "prod.example.com"

Step 3: Write configurarion for copying resources

Add the following Terraform configuration to the main.tf:

// main.tf terraform { required_providers { gcore = { source = "G-Core/gcore" version = ">= 0.8.20" } } } provider "gcore" { permanent_api_token = var.api_token api_endpoint = var.api_endpoint } resource "gcore_cdn_resource" "example" { cname = var.cdn_resource_cname origin = "example.com" }

Step 4: Use Terraform workspaces

Terraform workspaces allow you to manage multiple environments using the same configuration.

Initialize Terraform: terraform init

Then create workspaces for preproduction and production:

terraform workspace new preprod terraform workspace new production

Step 5: Apply the configuration

Switch to the staging workspace and apply the configuration:

terraform workspace select staging terraform apply -var-file=preprod.tfvars

Then switch to the production workspace and apply the configuration there as well:

terraform workspace select production terraform apply -var-file=production.tfvars

By using Terraform workspaces and variable files, you can apply the same configuration to different environments with a few commands.
