Terraform GitLab CI/CD Pipeline for AWS Infrastructure

This repository contains a GitLab CI/CD configuration for managing AWS infrastructure using Terraform. The pipeline automates the workflow from initialization and validation to planning and deployment.

Pipeline Overview

The CI/CD pipeline consists of the following stages:

1. Prepare: Initializes the Terraform environment and sets up necessary configurations.
2. Validate: Validates the Terraform configuration for syntax and best practices.
3. Build: Generates a Terraform execution plan and produces a JSON representation.
4. Deploy: Applies Terraform changes to the AWS environment (manual trigger to prevent accidental execution).

Configuration Details

Docker Image

The pipeline uses the official Terraform Docker image provided by GitLab.
