Terraform AWS Setup Demo

This Terraform configuration sets up a basic AWS infrastructure with an EC2 instance, an Internet Gateway, a route table, and security group rules.

Prerequisites

• Terraform installed (Download)
• AWS CLI installed and configured with an IAM user (Guide)
• AWS credentials profile set up (~/.aws/credentials)

Resources Created

1. Internet Gateway

• Attaches an Internet Gateway to the specified VPC.
• Creates a public route table to allow internet access.

2. EC2 Instance

• Deploys an EC2 instance within the specified subnet.
• Assigns a public IP to the instance.
• Associates the instance with a security group.

3. Security Groups

• Ingress Rules:
  • Allow HTTP traffic (ports 80-100) from all sources.
  • Plan to allow HTTPS traffic (port 443) from all sources.
  • Allow SSH access (port 22) from all sources.
• Egress Rules:
  • Allow all outbound traffic.

Variables

The following variables should be defined in a terraform.tfvars file or passed via CLI:

vpc_id = "your-vpc-id"
subnet = "your-subnet-id"
profile-id = "your-aws-profile"
ami = "your-ami-id"
instance_type = "t2.micro"

Usage

1. Initialize Terraform

   terraform init

2. Plan the deployment

   terraform plan

3. Apply the configuration

   terraform apply -auto-approve

4. Destroy the infrastructure (if needed)

   terraform destroy -auto-approve

Backup Strategy

This project includes a custom Python script to create PostgreSQL database backups and upload them to Amazon S3 for secure, durable storage.

🧪 Running the Backup

To run the backup manually, execute the following command in your terminal:

  PGPASSWORD='your_password' python3 backup/backup_to_s3.py

Notes

• Ensure that the provided vpc_id and subnet exist within your AWS account.
• Modify the security group settings as needed for your use case.
