TODO APP With User Details

Overview

This project uses Docker Compose to set up a MongoDB, backend, and frontend service. The services communicate with each other to provide a fully functional application environment.

Services

1. MongoDB

• Image: mongodb/mongodb-community-server:latest
• Container Name: mongodb-database-1
• Restart Policy: Always
• Ports: 27017:27017
• Volume: mongo_data:/data/db
• Environment Variables:
  • MONGO_INITDB_DATABASE=mydb

2. Backend Service

• Build Context: ./backend-service
• Container Name: backend-service
• Restart Policy: Always
• Depends On: mongodb
• Ports: 3002:3002
• Environment Variables:
  • MONGO_URI=mongodb://mongodb:27017/todoapp
  • PORT=3002

3. Frontend Service

• Build Context: ./frontend-service
• Container Name: frontend-service
• Restart Policy: Always
• Depends On: backend
• Ports: 8080:8081
• Environment Variables:
  • REACT_APP_BACKEND_URL=http://backend:3002

Running the Application

1. Clone the Repository

git clone <your-repo-url>
cd <your-repo-name>

2. Start Services

To build and run all services in detached mode:

docker-compose up --build -d

3. Verify Running Containers

Check if all containers are running:

docker ps

4. Stopping Services

To stop and remove containers:

docker-compose down

Persistent Data

• The MongoDB service uses a Docker volume (mongo_data) to persist database data.
• To remove persistent data, delete the volume using:

  docker volume rm mongo_data

Notes

• Ensure Docker and Docker Compose are installed before running the setup.
• The backend should be fully initialized before frontend requests data.
• If using init.db.js, ensure MongoDB is fully ready before executing it manually:

  docker exec backend-service node init.db.js
