## Wireguard
This example provides a base setup for using [Wireguard](https://www.wireguard.com/).
More details on how to customize the installation and the compose file can be found in [linuxserver documentation](https://hub.docker.com/r/linuxserver/wireguard).
Project structure:
```
.
├── .env
├── docker-compose.yaml
└── README.md
```
[_docker-compose.yaml_](docker-compose.yaml)
``` yaml
services:
wireguard:
image: linuxserver/wireguard
```
## Configuration
### .env
Before deploying this setup, you need to configure the following values in the [.env](.env) file.
- TIMEZONE
- VPN_SERVER_URL (recommended setting up a server url with e.g. http://www.duckdns.org/ if you don't own a domain)
## Deploy with docker-compose
When deploying this setup, the log will show relevant information. You need to forward the external port 51820 to access your VPN from outside.
``` shell
$ docker-compose up
Starting wireguard ...
wireguard | **** It seems the wireguard module is already active. Skipping kernel header install and module compilation. ****
wireguard | **** Server mode is selected ****
wireguard | **** External server address is set to your-domain.dyndns.com # free examples http://www.duckdns.org/ and https://www.noip.com/ ****
wireguard | **** External server port is set to 51820. Make sure that port is properly forwarded to port 51820 inside this container ****

## Expected result
Check containers are running:
```
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

```
## Troubleshooting
### - (Raspberry Pi) Kernel Headers
On Raspberry Pi run `sudo apt update && sudo apt upgrade && sudo apt install raspberrypi-kernel-headers` and reboot before starting Wireguard.
Other Ubuntu / Debian based systems may need to install the kernel-headers too. Run `sudo apt update && sudo apt upgrade && sudo apt install linux-headers-$(uname -r)`
### - Server Mode Options
To create new clients or display existing ones, take a look at the "[Server Mode](https://hub.docker.com/r/linuxserver/wireguard)" section
