# wireguard-ui
A web user interface to manage your WireGuard setup.
## Features
- Friendly UI
- Authentication
- Manage extra client's information (name, email, etc)
- Retrieve configs using QR code / file
## Run WireGuard-UI
Default username and password are `admin`.
### Using binary file
Download the binary file from the release and run it with command:
```
./wireguard-ui
```
### Using docker compose
You can take a look at this example of [docker-compose.yml](https://github.com/ngoduykhanh/wireguard-ui/blob/master/docker-compose.yaml). Please adjust volume mount points to work with your setup. Then run it like below:
```
docker-compose up
```
Note:
- There is a Status option 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
- 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.

### Email configuration
To use custom `wg.conf` template set the `WG_CONF_TEMPLATE` environment variable to a path to such file. Make sure `wireguard-ui` will be able to work with it - use [default template](templates/wg.conf) for reference.
In order to sent the wireguard configuration to clients via email, set the following environment variables:
- using SendGrid API
```
SENDGRID_API_KEY: Your sendgrid api key
EMAIL_FROM_ADDRESS: the email address you registered on sendgrid
EMAIL_FROM_NAME: the sender's email address
```
- using SMTP
```
SMTP_HOSTNAME: The SMTP ip address or hostname
SMTP_PORT: the SMTP port
SMTP_USERNAME: the SMTP username to authenticate
SMTP_PASSWORD: the SMTP user password
SMTP_AUTH_TYPE: the authentication type. Possible values: PLAIN, LOGIN, NONE
SMTP_ENCRYPTION: the encryption method. Possible values: SSL, SSLTLS, TLS or STARTTLS (default)
EMAIL_FROM_ADDRESS: the sender's email address
EMAIL_FROM_NAME: the sender's name
```
## 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:
### systemd
Create /etc/systemd/system/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
```
Create /etc/systemd/system/wgui.path
```
[Unit]
Description=Watch /etc/wireguard/wg0.conf for changes
[Path]
PathModified=/etc/wireguard/wg0.conf
[Install]
WantedBy=multi-user.target
```
Apply it
```
systemctl enable wgui.{path,service}
systemctl start wgui.{path,service}
```
### openrc
Create and `chmod +x` /usr/local/bin/wgui
```
#!/bin/sh
wg-quick down wg0
wg-quick up wg0
```
Create and `chmod +x` /etc/init.d/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
```
Apply it
```
rc-service wgui start
rc-update add wgui default
```
## 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
```
