# Docker Setup for Digital Twin Monitoring

This document provides instructions for setting up and running the Digital Twin Monitoring application using Docker.

## Prerequisites

- Ubuntu server
- Internet connection
- Basic knowledge of terminal commands

## Quick Start

The easiest way to get started is to run the provided installation script:

```bash
chmod +x install.sh
./install.sh
```

This script will:
1. Check if Docker is installed and install it if needed
2. Build the Docker image
3. Stop any existing containers with the same name
4. Start a new container with the application

Alternatively, you can use Docker Compose:

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

After running either method, the application will be available at `http://[server-ip]:5003`.

## Manual Setup

If you prefer to set up manually, follow these steps:

### 1. Build the Docker image

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

### 2. Run the Docker container

```bash
docker run -d \
  --name digital-twin-monitoring \
  --restart unless-stopped \
  -p 5003:5003 \
  --env-file .env \
  digital-twin-monitoring
```

## Environment Variables

The application uses the following environment variables from the `.env` file:

- `TELEGRAM_BOT_TOKEN`: Token for Telegram bot notifications
- `TELEGRAM_CHAT_ID`: Chat ID for Telegram notifications
- `DB_HOST_1`: PostgreSQL host for tables: pf_parts, ms_equipment_master
- `DB_HOST_2`: PostgreSQL host for table: dl_pi_fetch_last
- `DB_PORT`: PostgreSQL port
- `DB_USER`: PostgreSQL username
- `DB_PASS`: PostgreSQL password
- `DB_NAME`: PostgreSQL database name

Make sure your `.env` file is properly configured before running the container.

## Maintenance

### Viewing logs

```bash
docker logs digital-twin-monitoring
```

### Stopping the container

```bash
docker stop digital-twin-monitoring
```

### Restarting the container

```bash
docker restart digital-twin-monitoring
```

### Removing the container

```bash
docker stop digital-twin-monitoring
docker rm digital-twin-monitoring
```

### Updating the application

#### Using Docker Compose (Recommended)

To update the application using Docker Compose, simply pull the latest code and restart the services:

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

This will automatically rebuild the image if needed and restart the container with the updated code.

#### Using Docker Commands

Alternatively, you can update using individual Docker commands:

```bash
git pull
docker build -t digital-twin-monitoring -f Docker/Dockerfile .
docker stop digital-twin-monitoring
docker rm digital-twin-monitoring
docker run -d \
  --name digital-twin-monitoring \
  --restart unless-stopped \
  -p 5003:5003 \
  --env-file .env \
  digital-twin-monitoring
```
