Directory and File Descriptions

• modules/: Contains reusable Terraform modules.
• main.tf: Main Terraform configuration file.
• provider.tf: Configuration for Terraform providers (e.g., AWS).
• terraform.tfvars: Contains variable values for the Terraform configuration.
• variables.tf: Defines the variables used in the Terraform configuration.
• .github/workflows/terraform.yml: GitHub Actions workflow for Terraform CI/CD pipeline.

Prerequisites

• Terraform installed locally
• AWS account and IAM user with appropriate permissions
• GitHub repository with the necessary secrets configured

Setup

Configure AWS Credentials

Store your AWS credentials as secrets in your GitHub repository:

• AWS_ACCESS_KEY: Your AWS access key.
• AWS_SECRET_ACCESS_KEY: Your AWS secret access key.

Terraform Configuration

Edit the terraform.tfvars file to set your desired values for the Terraform variables.

GitHub Actions Workflow

The GitHub Actions workflow is defined in .github/workflows/terraform.yml:

name: Terraform CI CD Pipeline for Deploying AWS Resources
run-name: ${{ github.actor }} has triggered the pipeline

on:
  push:
    branches:
      - 'main'

env:
  AWS_ACCESS_KEY: ${{ secrets.AWS_ACCESS_KEY }}
  AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}

jobs:
  build-infra:
    name: terraform-ci-cd
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: Set up Terraform
        uses: hashicorp/setup-terraform@v2
      - name: Terraform Init
        id: init
        run: terraform init
        working-directory: ./Terraform-VPC
      - name: Terraform Validate
        id: validate
        run: terraform validate
        working-directory: ./Terraform-VPC
      - name: Terraform Plan
        id: plan
        run: terraform plan
        working-directory: ./Terraform-VPC
      - name: Terraform Apply
        id: apply
        run: terraform apply --auto-approve
        working-directory: ./Terraform-VPC
