# Public IP tracker

[![Build Status](https://drone.faercol.me/api/badges/faercol/public-ip-tracker/status.svg)](https://drone.faercol.me/faercol/public-ip-tracker)


Telegram bot that detects changes to the device's public IP. This is particularily useful when
the device is handled by an ISP that does not provide a static public IP, such as a home device.

## Features

### Automatic public IP detection and monitoring

Upon startup, the current public IP is detected, and a status message is sent to a specific Telegram
channel with the relevant information.

> Insert example message here

When running as a daemon, the program automatically monitors the current public IP adress for changes.
If the IP changes for some reason, then the new updated adress is sent to the specific Telegram
channel.

### On-demand public IP

The relevant channel is monitored during the program execution. This allows the user to send a
command to the bot in order to get the current public IP on-demand.

## Deploy

### Configuration file

For now, the program is configured through a JSON configuration file. Here is a sample :

```json
{
    "telegram": {
        "token": "<your_bot_token>",
        "channel_id": 9999999
    },
    "polling_frequency": 5,
    "log": {
        "level": "info"
    }
}
```


### Docker

You can use the provided Dockerfile to build your own image.

```bash
docker build -t public-ip-tracker .
```

You can then use the provided configuration file sample, and provide it to the program using the
`/config` volume

> I might add support for environment variables in the future.

```bash
docker run -it -v /path/to/your/dir/with/json/file:/config public-ip-tracker
```
