Terraform Examples

Welcome to the Terraform Examples repository! This repository serves as a collection of Infrastructure as Code (IaC) templates, modules, and best practices using HashiCorp Terraform. It is designed to help developers and DevOps engineers quickly deploy and manage cloud infrastructure.

🚀 About The Project

This repository contains a variety of Terraform configurations ranging from basic setups to more advanced architectures. Whether you are looking to provision a simple virtual machine, set up a managed Kubernetes cluster, or design a highly available multi-tier network, you'll find reference code here.

Goals:

• Provide ready-to-use infrastructure templates.
• Demonstrate Terraform best practices (state management, modules, variables).
• Serve as a learning resource for infrastructure automation.

🏁 Getting Started

1. Clone the repository:

   git clone [https://github.com/sinfallas/terraform-examples.git](https://github.com/sinfallas/terraform-examples.git)
   cd terraform-examples

2. Navigate to your desired example:

   cd aws/ec2-instance

3. Configure Variables: Most examples include a variables.tf file. Create a terraform.tfvars file to pass your specific values (e.g., region, instance types):

   aws_region = "us-east-1"
   instance_type = "t3.micro"

💻 Usage

Standard Terraform workflow applies to all examples:

1. Initialize the working directory (downloads providers and modules):

   terraform init

2. Review the execution plan (shows what will be created/modified):

   terraform plan

3. Apply the configuration (provisions the infrastructure):

   terraform apply

   (Type yes when prompted to confirm)
4. Destroy the infrastructure (cleans up resources to avoid unexpected charges):

   terraform destroy

🌟 Best Practices

When using or adapting these examples for production, please consider the following:

• Remote State: Always configure a remote backend (like AWS S3 + DynamoDB, Azure Storage, or Terraform Cloud) to store your .tfstate files securely.
• Least Privilege: Ensure the credentials used to run Terraform only have the permissions necessary to create the required resources.
• Version Pinning: Pin your Terraform provider versions to avoid breaking changes in future updates.
