#### Install guide for Docker
When using docker container any environment variables prefixed with `FOURGET_` will be added to the generated config located at `/var/www/html/4get/data/config.php`
#### Special environment variables
| Name | value | Example |
| - | - | - |
| FOURGET_PROTO | "http" or "https" | "https" |
| FOURGET_INSTANCES | comma separated string of urls | "https://4get.ca,https://domain.tld" |
#### Important directories
| Mountpoint | Description |
| - | - |
| /etc/4get/certs | SSL certificate directory |
| /var/www/html/4get/banner | Custom Banners directory |
| /var/www/html/4get/data/captcha | Captcha dataset |
the certificate directory `/etc/4get/certs` expects files named `fullchain.pem` and `privkey.pem`
The captcha dataset should have a subdirectory for each category. In each category, images should be named from 1.png to X.png, and be 100x100 in size.
example directory structure:
```
captcha/
birds/
1.png
2.png
3.png
anime/
1.png
2.png
```
For more information on configuration view [data/config.php](../data/config.php)
