# WG-Dashboard Docker Explanation:
# WGDashboard Docker Explanation:
Author: DaanSelen<br>
This document delves into how the WG-Dashboard Docker container has been built.<br>
This document delves into how the WGDashboard Docker container has been built.<br>
Of course there are two stages, one before run-time and one at/after run-time.<br>
The `Dockerfile` describes how the container image is made, and the `entrypoint.sh` is executed after running the container. <br>
In this example, WireGuard is integrated into the container itself, so it should be a run-and-go.<br>
In this example, WireGuard is integrated into the container itself, so it should be a run-and-go/out-of-the-box.<br>
For more details on the source-code specific to this Docker image, refer to the source files, they have lots of comments.
I have tried to embed some new features such as `isolated_peers` and interface startup on container-start (through `enable_wg0`).

## Getting the container running:
To get the container running you either pull the image from the repository, at the moment: `repo.nerthus.nl/app/wireguard-dashboard:latest`.<br>
To get the container running you either pull the image from the repository, `dselen/wgdashboard:latest`.<br>
From there either use the environment variables describe below as parameters or use the Docker Compose file: `compose.yaml`.
An example of a simple command to get the container running is show below:<br>

Once the container is running, the installation process is essentially the same as running it on bare-metal.<br>
So go to the assign TCP port in this case HTTP, like the default 10086 one in the example and log into the WEB-GUI.<br>
| Environment variable | Accepted arguments | Default value | Verbose |
| -------------- | ------- | ------- | ------- |
| tz | Europe/Amsterdam or any confirming timezone notation. | Europe/Amsterdam | Sets the timezone of the Docker container. This is to timesync the container to any other processes which would need it. |
| global_dns | Any IPv4 address, such as my personal recommendation: 9.9.9.9 (QUAD9) | 1.1.1.1 | Set the default DNS given to clients once they connect to the WireGuard tunnel (VPN).
| enable_wg0 | `true` or `false` | `false` | Enables or disables the starting of the WireGuard interface on container 'boot-up'.
| isolated_peers | `true` or `false` | `true` | For security the default is true, and it disables peers to ping or reach eachother, the WireGuard interface IS able to reach the peers (Done through `iptables`).
| public_ip | Any IPv4 (public recommended) address, such as the one returned by default | Default uses the return of `curl ifconfig.me` | To reach your VPN from outside your own network, you need WG-Dashboard to know what your public IP-address is, otherwise it will generate faulty config files for clients.

| tz | Europe/Amsterdam or any confirming timezone notation. | `Europe/Amsterdam` | `America/New_York` | Sets the timezone of the Docker container. This is to timesync the container to any other processes which would need it. |
| global_dns | Any IPv4 address, such as my personal recommendation: 9.9.9.9 (QUAD9). | `1.1.1.1` | `8.8.8.8` or any IP-Address that resolves DNS-names, and of course is reachable | Set the default DNS given to clients once they connect to the WireGuard tunnel, and for new peers, set to Cloudflare DNS for reliability.
| enable | Anything, preferably an existing WireGuard interface name. | `none` | `wg0,wg2,wg13` | Enables or disables the starting of the WireGuard interface on container 'boot-up'.
| isolate | Anything, preferably an existing WireGuard interface name. | `wg0` | `wg1,wg0` | For security premade `wg0` interface comes with this feature enabled by default. Declaring `isolate=` in the Docker Compose file will remove this. The WireGuard interface itself IS able to reach the peers (Done through the `iptables` package).
| public_ip | Any IPv4 (public recommended) address, such as the one returned by default | Default uses the return of `curl ifconfig.me` | `23.50.131.156` | To reach your VPN from outside your own network, you need WG-Dashboard to know what your public IP-address is, otherwise it will generate faulty config files for clients. This happends because it is inside a Docker/Kubernetes container. In or outside of NAT is not relevant as long as the given IP-address is reachable from the internet or the target network.
## Be careful with:
When you are going to work with multiple WireGuard interfaces, you need to also open them up to the Docker host. This done by either adding the port mappings like: `51821:51821/udp` in the Docker Compose file, or to open a range like: `51820-51830:51820-51830/udp`<br>
The latter opens up UDP ports from 51820 to 51830, so all ports in between as well! Be careful, it is good security practise to open only needed ports!
## Building the image yourself:
To build the image yourself, you need to do a couple things:<br>
1. Clone the Github repository containing the source code of WGDashboard including the docker directory. For example do: `git clone https://github.com/donaldzou/WGDashboard.git`
1. Navigate into the docker directory.
1. (Make sure you have Docker correctly installed, if not: [Click here](https://docs.docker.com/engine/install/)) and run: `docker build . -t <Image name>:<Image tag>` as an example: `docker build . -t dselen/wgdashboard:latest`.<br>This will make Docker compile the image from the resources in the directory you mention, in this case the current one. Let it compile, it takes about a minute or maximally two.
1. If all went well, see your image with `docker images`. Example below:
```
dselen@dev-mach:~/development/WGDashboard/docker$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
dselen/wgdashboard dev c96fd96ee3b3 42 minutes ago 314MB
```
## Closing remarks:
Excuse the large image size, whoops! Debian's big... sometimes.<br>
For feedback please submit an issue to the repository. Or message dselen@nerthus.nl.
