# 1. Overview 

## 1.1. Usage

The Program will listen for RoutingTable Changes and can translate the changes to a Wireguard-Interface.

It will detect the Peer to add the Route to using the Gateway from the Route-Entry.<br>
In case routes clash or cant be added to Wireguard, Warnings will be logged.

<br>

### 1.1.1. Examples

- Dynamic Routing with Routing-Protocols (e.g. OSPF)
- Interacting with Wireguard using the familiar Tools like `iproute2`

<br>

## 1.2. Install



<br>

### 1.2.1. Docker

Depending on the needs, the Container can be run in `network_mode: host` to be able to accessrouting-tables and interfaces of the host. 

<details><summary><code>docker-compose.yml</code></summary>

```yaml
version: '3'

services:
  routingTableWGTranslator:
    image: ruakij/RoutingTableWGTranslator
    restart: unless-stopped
    network_mode: "host"
    environment:
      - INTERFACE="<wgInterfaceName or empty for wg0>"
```
</details>

<br>

### 1.2.2. Without Docker

Clone the Repository `git clone <URI>` and build the Program with `go build cmd/app`

Then you can run it with `./app`
