🚀 Getting Started (Step-by-Step)

1️⃣ Install Required Tools

🔹 Download Terraform (v1.0.0 or newer) 🔹 Install AWS CLI and set up credentials using:

aws configure

🔹 Create an S3 bucket & DynamoDB table for storing Terraform state:

# Create S3 bucket
aws s3 mb s3://your-terraform-state-bucket --region us-east-1

# Create DynamoDB table (with 'LockID' as partition key)
aws dynamodb create-table \
    --table-name your-terraform-lock-table \
    --attribute-definitions AttributeName=LockID,AttributeType=S \
    --key-schema AttributeName=LockID,KeyType=HASH \
    --billing-mode PAY_PER_REQUEST \
    --region us-east-1

---

2️⃣ Clone the Project & Configure Variables

git clone https://github.com/NotHarshhaa/AWS-Terraform-Workshop.git
cd AWS-Terraform-Workshop

# Create a tfvars file with your specific values
cp terraform.tfvars.example terraform.tfvars
# Edit the terraform.tfvars file with your preferred editor

---

3️⃣ Initialize Terraform with Backend Configuration

# Basic initialization
terraform init

# Or with custom backend configuration
terraform init \
  -backend-config="bucket=your-terraform-state-bucket" \
  -backend-config="dynamodb_table=your-terraform-lock-table" \
  -backend-config="region=us-east-1"

👉 This sets up Terraform by downloading necessary plugins and configuring remote state.

---

4️⃣ Plan & Apply Changes

# Preview changes
terraform plan -out=tfplan

# Apply the saved plan
terraform apply tfplan

# Or directly apply (will prompt for confirmation)
terraform apply

⚡ This will create a complete infrastructure including:

• VPC with proper CIDR blocks
• Public subnet with internet connectivity
• Security groups with configurable ports
• EC2 instance with Apache web server

---

5️⃣ Test the Deployment & View Outputs

# View all the output values
terraform output

# Get a specific output value (e.g., web server URL)
terraform output web_url

# SSH to your instance
terraform output ssh_connection_string
# Then modify the command with the actual path to your key file

6️⃣ Destroy Infrastructure (When Finished)

# Preview what will be destroyed
terraform plan -destroy

# Destroy all resources
terraform destroy

⛔ This will delete all deployed AWS resources.

📝 Best Practices for Beginners

🔹 Always use Remote State – Store Terraform state in S3 to prevent conflicts.
🔹 Use Variables and Outputs – Parameterize your code for flexibility. 🔹 Separate User Data Scripts – Keep bootstrap scripts in separate files. 🔹 Apply Proper Tagging – Tag resources consistently for better management. 🔹 Use Dynamic Blocks – For repeatable resource configurations. 🔹 Check Plan Before Applying – Always run terraform plan first!
🔹 Security First – Restrict security group rules to minimum required access.
