# Docker Setup for Digital Twin Monitoring Application

This folder contains Docker configuration files for deploying the Digital Twin Monitoring application in a production environment.

## Files

- `Dockerfile`: Defines how to build the application container
- `docker-compose.yml`: Defines the services and their configurations

## Prerequisites

- Docker and Docker Compose installed on your production server
- Access to PostgreSQL databases (configured in environment variables)

## Deployment Instructions

### Option 1: Using Docker Compose (Recommended)

1. Copy the entire project to your production server
2. Navigate to the project root directory
3. Make sure your `.env` file is properly configured with:
   - `TELEGRAM_BOT_TOKEN`
   - `TELEGRAM_CHAT_ID`
   - Database connection details (optional, defaults are provided)
4. Run the following command:

```bash
cd Docker
docker-compose up -d
```

This will:
- Build the Docker image using the Dockerfile
- Start the container in detached mode
- Map port 5003 to the host
- Configure environment variables
- Set up restart policies

### Option 2: Using Docker Directly

If you prefer to use Docker without Docker Compose:

1. Copy the entire project to your production server
2. Navigate to the project root directory
3. Build the Docker image:

```bash
docker build -t digital-twin-monitoring -f Docker/Dockerfile .
```

4. Run the container:

```bash
docker run -d \
  --name digital-twin-app \
  -p 5003:5003 \
  -e DB_HOST_1=192.168.1.85 \
  -e DB_HOST_2=192.168.1.86 \
  -e DB_PORT=5432 \
  -e DB_USER=postgres \
  -e DB_PASS=postgres \
  -e DB_NAME=digital_twin \
  -e TELEGRAM_BOT_TOKEN=your_token \
  -e TELEGRAM_CHAT_ID=your_chat_id \
  --restart unless-stopped \
  digital-twin-monitoring
```

Replace `your_token` and `your_chat_id` with your actual Telegram credentials.

## Accessing the Application

Once deployed, the application will be available at:

```
http://your-server-ip:5003
```

## Maintenance

### Viewing Logs

```bash
# Using Docker Compose
docker-compose logs -f

# Using Docker directly
docker logs -f digital-twin-app
```

### Stopping the Application

```bash
# Using Docker Compose
docker-compose down

# Using Docker directly
docker stop digital-twin-app
docker rm digital-twin-app
```

### Updating the Application

1. Pull the latest code changes
2. Rebuild and restart:

```bash
# Using Docker Compose
docker-compose down
docker-compose up -d --build

# Using Docker directly
docker stop digital-twin-app
docker rm digital-twin-app
docker build -t digital-twin-monitoring -f Docker/Dockerfile .
# Then run the container again with the same parameters as above
```
