Terraform_101_Advanced

This repository contains a set of Terraform configurations that interact with multiple cloud providers (Vultr, AWS, and GCP) to provision and manage resources. It follows best practices for organizing Terraform files and managing state.

📂 Repository Structure

The repository consists of the following directories and files:

Root directory: Contains primary configuration files including main.tf, variables.tf, outputs.tf.
prod/ and stage/: House environment-specific configurations and state files.
modules/: Holds modules for each cloud provider - Vultr, AWS, GCP.

Each provider module (within vultr/, aws/, gcp/) has its own main.tf, variables.tf, and outputs.tf, which help configure resources for the respective provider.

📌 Prerequisites

Before you begin, ensure that you have the following installed:

Terraform: Follow the instructions here for installation.
Provider CLIs: Install CLI tools for each cloud provider:
- AWS CLI: Follow the instructions here.
- Google Cloud SDK: Follow the instructions here.
- Vultr CLI: Follow the instructions here.

You also need to have accounts and appropriate permissions on Vultr, AWS, and GCP.

🚀 Usage

Important: Before running any Terraform commands, navigate to the appropriate environment directory (prod or stage).

Initialize Terraform - This downloads the necessary provider plugins.
```
terraform init
```
Validate the configuration - This command checks the syntax of the Terraform files.
```
terraform validate
```
Plan the changes - This command shows what actions Terraform will perform.
```
terraform plan
```
Apply the changes - This command creates or updates the resources.
```
terraform apply
```
Destroy the resources - When you no longer need the resources, you can delete them.
```
terraform destroy
```

📚 Further Reading
