Terraform Infrastructure Deployment for DigitalOcean

This repository contains Terraform configuration files to deploy a simple infrastructure on DigitalOcean. This infrastructure includes the creation of a VPC, two Droplets (virtual machines), a domain, and a Spaces bucket.

Prerequisites

Before you can use these Terraform configurations, make sure you have the following prerequisites in place:

• Terraform installed on your local machine.
• A DigitalOcean account.
• DigitalOcean API Token for authentication.
• Your DigitalOcean Spaces secret key for accessing Spaces resources.

Getting Started

1. Clone this repository to your local machine.

2. Create a digitalocean.tfvars file in the same directory as the Terraform configuration files with the following content:

# List of SSH keys
ssh_pub_keys = []

# Your project name
projet_name = "demo"

# Your project description
projet_description = "Your project description"

# Your desired domain name
projet_domain = "example.com"

# Your DigitalOcean Personal API Token
digitalocean_token = "your_digitalocean_api_token"

# Choose your preferred region
digitalocean_region = "nyc1"

# Your DigitalOcean Spaces access id
digitalocean_spaces_access_id = "your_spaces_access_id"

# Your DigitalOcean Spaces secret key
digitalocean_spaces_secret_key = "your_spaces_secret_key"

# List of permitted origin domains for accessing your DigitalOcean Spaces bucket
digitalocean_spaces_allowed_origins = ["https://www.example.com"]  # Origins for PUT, POST, DELETE requests

3. Customize the digitalocean.tfvars file with your specific values.

4. Initialize Terraform by running the following command in the repository directory:

terraform init  -var-file=digitalocean.tfvars

5. Deploy the infrastructure by running:

terraform apply -var-file=digitalocean.tfvars

6. Remove the infrastructure by running:

terraform destroy -var-file=digitalocean.tfvars

Confirm the changes when prompted.

Terraform Configuration

• The main.tf file contains the Terraform configuration, including the DigitalOcean provider setup and the definition of various resources such as VPC, Droplets, Domain, and Spaces bucket.

• The resources are parameterized using variables, and their values can be provided via the digitalocean.tfvars file.

Cleaning Up

To destroy the infrastructure and clean up resources, run the following command:

terraform destroy -var-file=digitalocean.tfvars

Confirm the destruction when prompted.

Outputs

After deploying the infrastructure, you can retrieve the following information using the terraform output command:

• output_server_middleware_ips: IP address of the middleware Droplet.
• output_server_application_ips: IP address of the application Droplet.

Conclusion

This Terraform configuration automates the deployment of a simple infrastructure on DigitalOcean. You can customize it further by providing your specific values in the digitalocean.tfvars file.
