How to Create A deployed site

1. Prerequisites

✅ Access an active AWS account.

✅ Create an IAM user with necessary permissions.

2. Local Testing

✅ Verify that the frontend-backend test server works locally without issues.

3. Subdomain Configuration

✅ Set up a DNS endpoint in AWS Route 53:

• Server: https://striver.stu.nighthawkcodingsociety.com/
• Domain: nighthawkcodingsociety.com
• Subdomain: striver.stu

4. Backend Port Settings

✅ main.py: Confirm the server listens on port 8503:

  if __name__ == "__main__":
      app.run(debug=True, host="0.0.0.0", port=8503)

✅ Dockerfile: Ensure it’s configured to run the server:

• Install dependencies.
• Expose port 8503.
• Set FLASK_ENV to deployed.

✅ docker-compose.yml: Define services:

• Map port 8503 correctly.
• Ensure environment variables are set.

✅ Nginx Configuration: Set up reverse proxy:

• Listen on port 80 (do NOT change to 8503).
• Proxy traffic to localhost:8503.

5. Frontend Integration

✅ Update frontend code to detect environment and route requests:

  export var pythonURI;
  if (location.hostname === "localhost" || location.hostname === "127.0.0.1") {
      pythonURI = "http://localhost:8503";
  } else {
      pythonURI = "https://striver.stu.nighthawkcodingsociety.com";
  }

6. Launching an EC2 Instance

✅ Log into AWS Console → Go to EC2 Dashboard. To login to the deployment server on AWS EC2 you will use cockpit backdoor. https://cockpit.stu.nighthawkcodingsociety.com/

✅ Launch a new EC2 instance.

7. Application Deployment

✅ Ensure port 8503 is open and accessible:

  docker ps

✅ Build the Docker container:

  docker-compose build
  docker-compose up -d

8. Server Configuration

✅ Clone the backend repository to the EC2 instance:

  git clone https://github.com/RayhaanSheeraj/StriverrBackend.git  striverr_backend
  cd striverr_backend
  curl localhost:8503

✅ Configure Route 53 DNS for the subdomain.

✅ Set up Nginx:

  cd /etc/nginx/sites-available
  sudo nano striverr.nginx_file  striverr.stu
  cd /etc/nginx/sites-enabled
  sudo ln -s /etc/nginx/sites-available/striverr.stu /etc/nginx/sites-enabled
  sudo nginx -t
  sudo systemctl restart nginx

Use the

  cat striverr.stu

to check that the contents of the nginx file are correctly copied into striverr.stu in sites-available.

✅ Secure the server with Certbot (SSL):

  sudo certbot --nginx

9. Updating the Deployment

✅ Pull the latest changes from the repository:

  cd ~/striverr_backend
  docker-compose down
  git pull
  docker-compose build
  docker-compose up -d
  sudo cp -f striverr.nginx_file /etc/nginx/sites-available/striverr.stu

✅ Troubleshoot if needed:

  curl localhost:8503
  docker ps
