wireguard-ui

A web user interface to manage your WireGuard setup.

Features

• Friendly UI
• Authentication
• Manage extra client information (name, email, etc)
• Retrieve client config using QR code / file / email

Run WireGuard-UI

⚠️The default username and password are admin. Please change it to secure your setup.

Using binary file

Download the binary file from the release page and run it directly on the host machine

./wireguard-ui

Using docker compose

You can take a look at this example of docker-compose.yml. Please adjust volume mount points to work with your setup. Then run it like below:

docker-compose up

Note:

• There is a Status page that needs docker to be able to access the network of the host in order to read the wireguard interface stats. See the cap_add and network_mode options on the docker-compose.yaml
• Similarly, the WGUI_MANAGE_START and WGUI_MANAGE_RESTART settings need the same access, in order to restart the wireguard interface.
• Because the network_mode is set to host, we don't need to specify the exposed ports. The app will listen on port 5000 by default.

WGUI_MANAGE_RESTART	Auto restart WireGuard when we Apply Config changes in the UI	false

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 [email protected]

[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 -t wireguard-ui .

Build binary file

Prepare the assets directory

./prepare_assets.sh

Then you can embed resources by generating Go source code

rice embed-go
go build -o wireguard-ui

Or, append resources to executable as zip file

go build -o wireguard-ui
rice append --exec wireguard-ui
