Auto restart WireGuard daemon

WireGuard-UI only takes care of configuration generation. You can use systemd to watch for the changes and restart the service. Following is an example:

Using systemd

Create /etc/systemd/system/wgui.service

cd /etc/systemd/system/
cat << EOF > wgui.service
[Unit]
Description=Restart WireGuard
After=network.target

[Service]
Type=oneshot
ExecStart=/usr/bin/systemctl restart wg-quick@wg0.service

[Install]
RequiredBy=wgui.path
EOF

Create /etc/systemd/system/wgui.path

cd /etc/systemd/system/
cat << EOF > wgui.path
[Unit]
Description=Watch /etc/wireguard/wg0.conf for changes

[Path]
PathModified=/etc/wireguard/wg0.conf

[Install]
WantedBy=multi-user.target
EOF

Apply it

systemctl enable wgui.{path,service}
systemctl start wgui.{path,service}

Using openrc

Create /usr/local/bin/wgui file and make it executable

cd /usr/local/bin/
cat << EOF > wgui
#!/bin/sh
wg-quick down wg0
wg-quick up wg0
EOF
chmod +x wgui

Create /etc/init.d/wgui file and make it executable

cd /etc/init.d/
cat << EOF > wgui
#!/sbin/openrc-run

command=/sbin/inotifyd
command_args="/usr/local/bin/wgui /etc/wireguard/wg0.conf:w"
pidfile=/run/${RC_SVCNAME}.pid
command_background=yes
EOF
chmod +x wgui

Apply it

rc-service wgui start
rc-update add wgui default

Using Docker

Set WGUI_MANAGE_RESTART=true to manage Wireguard interface restarts. Using WGUI_MANAGE_START=true can also replace the function of wg-quick@wg0 service, to start Wireguard at boot, by running the container with restart: unless-stopped. These settings can also pick up changes to Wireguard Config File Path, after restarting the container. Please make sure you have --cap-add=NET_ADMIN in your container config to make this feature work.

Build

Build docker image

Go to the project root directory and run the following command:

docker build --build-arg=GIT_COMMIT=$(git rev-parse --short HEAD) -t wireguard-ui .

or

docker compose build --build-arg=GIT_COMMIT=$(git rev-parse --short HEAD)

ℹ️ A container image is avaialble on Docker Hub which you can pull and use

docker pull ngoduykhanh/wireguard-ui

Build binary file

Prepare the assets directory

./prepare_assets.sh

Then build your executable

go build -o wireguard-ui
