🚀 github-actions-cicd: Streamlined Infrastructure Deployment with GitHub Actions

🧭 Overview

This repository provides a robust, reusable CI/CD pipeline built with GitHub Actions for managing Terraform-based infrastructure.
Designed for efficiency and consistency, it enables automated and manual deployments across multiple environments — ensuring high-quality, reliable, and secure infrastructure provisioning.

✨ Key Features

🧩 Automated Pull Request Deployments

• Automatically detects changes in Terraform directories within pull requests.
• Extracts Terraform workspace names from PR descriptions.
• Dynamically selects GitHub environments for secure secret management.
• Performs terraform plan and posts results directly to the pull request for review.

⚙️ Manual On-Demand Deployments

• Supports manual triggering for specific resource directories and Terraform workspaces.
• Enables controlled terraform plan and terraform apply operations for targeted updates.

🌐 Flexible Environment Management

• Categorizes environments into prod, nonprod, and mgmt classes.
• Supports distinct stages like dev, qa, stag, uat, prodgreen, and prodblue.
• Enforces isolation by recommending separate Terraform modules and state files for each environment.

✅ Code Quality and Consistency

• Integrates pre-commit hooks for:
  • terraform fmt
  • terraform validate
  • terraform tflint
• Ensures consistent, error-free, and high-quality Terraform code before every commit.

🔧 Example Workflow Snippet

name: Terraform CI/CD

on:
  pull_request:
    paths:
      - 'terraform/**'
  workflow_dispatch:

jobs:
  terraform:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: hashicorp/setup-terraform@v3
        with:
          terraform_version: 1.6.6

How to Use:

1. Fork or Clone this repository.
2. Configure GitHub Environments (dev, qa, prod) and add required secrets (e.g., cloud credentials, Terraform backend config).
3. Structure your infrastructure under /terraform:

   terraform/
   ├── dev/
   ├── qa/
   ├── prod/
   └── mgmt/
   

4. Trigger Deployment:
   • Pull Request: Runs terraform plan automatically.
   • Manual Dispatch: Allows selective plan or apply execution.
