# Docker Manager Bot

Telegram bot for managing Docker containers on Unraid. Control containers from your phone with simple keyword commands.

## Prerequisites

- Unraid server with Docker enabled
- n8n container running on Unraid
- Telegram Bot Token (from [@BotFather](https://t.me/botfather))
- Your Telegram User ID (from [@userinfobot](https://t.me/userinfobot))

## Installation

### 1. Configure n8n Container

Your n8n container needs Docker socket access to manage other containers. Add these flags to your n8n container configuration:

```bash
docker run -d \
  --name n8n \
  --group-add 281 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /path/to/curl:/usr/bin/curl:ro \
  -p 5678:5678 \
  n8nio/n8n
```

**Required flags:**

- `--group-add 281` - Adds Docker group (GID 281 on Unraid) so n8n can access the Docker socket
- `-v /var/run/docker.sock:/var/run/docker.sock` - Mounts the Docker socket for container management
- `-v /path/to/curl:/usr/bin/curl:ro` - Mounts a static curl binary (hardened n8n image lacks package manager)

If using Unraid's Community Applications, add these to the "Extra Parameters" and "Path" sections of your n8n container template.

### 2. Create Telegram API Credential

In the n8n web interface:

1. Go to Settings > Credentials > Add Credential
2. Search for "Telegram API"
3. Name: `Telegram API`
4. Access Token: paste your bot token from @BotFather

### 3. Import Workflow

1. Download `n8n-workflow.json` from this repository
2. In n8n: Workflows > Import from File
3. Select `n8n-workflow.json`
4. When prompted, map the `Telegram API` credential

### 4. Configure Your User ID

The workflow only responds to your Telegram user ID. To set it:

1. Open the imported workflow
2. Find the **IF User Authenticated** node
3. Click to edit, find the condition with `rightValue`
4. Change `563878771` to your Telegram user ID
5. Repeat for **IF Callback Authenticated** node
6. Save the workflow

### 5. Activate Workflow

1. Click the "Active" toggle in the top-right corner
2. Test by sending "status" to your bot in Telegram

## Usage

Send commands via Telegram or use the persistent menu buttons:

| Command | Description |
|---------|-------------|
| `status` | View all containers with status indicators |
| `start <name>` | Start a stopped container |
| `stop <name>` | Stop a running container |
| `restart <name>` | Restart a container |
| `update <name>` | Pull latest image and recreate container |
| `logs <name> [lines]` | View container logs (default: 50 lines) |

Container names support partial matching. For example, `start plex` will match `linuxserver-plex`.

### Menu Buttons

Send `/start` or any unrecognized text to display the persistent keyboard with quick-access buttons for all commands.

## Security

The bot only responds to the Telegram user ID configured in the IF nodes. Messages from other users are silently ignored.
