Installation

Requirements

Ensure you have the following installed:

• PgAdmin4
• JMeter
• Node.js and npm (for JavaScript dependencies)
• Python (for OR tools and other functionalities)
• Docker

Setup

1. Clone the repository:

git clone https://github.com/ntua/saas2024-55.git

2. Install dependencies: First, install Python dependencies specified in requirements.txt.

pip install -r requirements.txt

3. Connect Database: Connect Postgresql Database.

Docker

SimplySolved is Dockerized for easy deployment.

1. Build and run Docker containers:

docker-compose up --build

This commmand builds the Docker images and starts the containers defined in docker-compose.yml.

2. Verify container status: Run the following command in order to verify that all the necessary containers are running:

docker ps

Here are the microservices that should be running:

Solve My Problem - Microservices Architecture

This project is a microservices-based application designed to handle various aspects of a problem-solving platform. Each microservice is responsible for a specific task, such as user management, payment processing, problem submission, problem solving, and statistics generation. The system is orchestrated using Docker Compose.

Microservices

1. Payment Service

• Description: Handles payment transactions, including credit purchasing and balance management.
• Port: 3002
• Directory: ./payment-service

2. Problem Service

• Description: Allows users to submit problems, view them, and manage problem-related data.
• Port: 3003
• Directory: ./problem-service

3. Solver Service

• Description: This service manages the actual solving of the submitted problems. It has access to the Docker socket for running SDKs.
• Port: 5000
• Directory: ./solver-service
• Special Requirement: The Docker socket (/var/run/docker.sock) is mounted to allow the service to run containers dynamically.

4. Statistics Service

• Description: Provides statistics and analytics on user submissions, problem-solving performance, and platform usage.
• Port: 3004
• Directory: ./statistics-service

5. API Gateway

• Description: Acts as a reverse proxy, routing requests to the appropriate microservices. All client requests pass through this gateway.
• Port: 3000
• Directory: ./api-gateway

6. Frontend

• Description: The user interface for the platform. This service provides the web-based frontend for users to interact with the system.
• Port: 3006 (mapped to 80 internally)
• Directory: ./frontend

7. Backend

• Description: The core backend service. It interacts with the PostgreSQL database.
• Port: 3007
• Directory: ./backend
• Environment Variables:
  • POSTGRES_USER: postgres
  • POSTGRES_HOST: host.docker.internal
  • POSTGRES_DB: mydatabase
  • POSTGRES_PASSWORD: 123
  • POSTGRES_PORT: 5432

Network Configuration

All services are connected via the Docker bridge network named solveMyProblemNetwork. This allows inter-service communication and ensures isolation from external networks.
