Alternatively, as long as you have Wireguard on your host kernel with some Wireguard interfaces running, you can use Docker. For example:
```sh
docker build -t prometheusWireguardExporter https://github.com/mindflavor/prometheus_wireguard_exporter
docker run -it --rm --init --net=host --cap-add=NET_ADMIN prometheusWireguardExporter
# Check it's up
docker run -it --rm alpine:3.12 wget -qO- http://localhost:9586/metrics
```
