All WireGuard UI implementation are trying to manage the service by applying configurations and creating network rules.
This implementation only generate configuration and its up to you to create network rules and apply configuration to WireGuard.
For example by monituring generated directory with [inotifywait](https://github.com/inotify-tools/inotify-tools/wiki).

## How to trigger WireGuard on host
Before going further create a symlink from docker mounted volume to `/etc/wireguard`
```
ln -s /mnt/raid-lv-data/docker-persistent-data/wg-gen-web /etc/wireguard
```
### Example with ```systemd```
Using `systemd.path` monitor for directory changes see [systemd doc](https://www.freedesktop.org/software/systemd/man/systemd.path.html)
```
# /etc/systemd/system/wg-gen-web.path
[Unit]
Description=Watch /etc/wireguard for changes
[Path]
PathModified=/etc/wireguard
[Install]
WantedBy=multi-user.target
```
This `.path` will activate unit file with the same name
```
# /etc/systemd/system/wg-gen-web.service
[Unit]
Description=Restart WireGuard
After=network.target
[Service]
Type=oneshot
ExecStart=/usr/bin/systemctl restart wg-quick@wg0.service
[Install]
WantedBy=multi-user.target
```
Which will restart WireGuard service
### Example with ```inotifywait```
Using whatever init system create a daemon running this script
```
#!/bin/sh
while inotifywait -e modify -e create /etc/wireguard; do
wg-quick down wg0
wg-quick up wg0
done
```
