#### 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`

When lists of data is expected in [data/config.php](../data/config.php), such as `INSTANCES`, you can pass in a comma separated string via environment variable. 

Example:
`FOURGET_INSTANCES="https://4get.ca,https://domain.tld"`

#### Special environment variables

| Name              | value                          | Example                              |
| -                 | -                              | -                                    |
| FOURGET_PROTO     | "http" or "https"              | "https"                              |


#### 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)

#### Usage

You can start 4get with

```
docker run -d -p 80:80 -e FOURGET_SERVER_NAME="4get.ca" -e FOURGET_PROTO="http" luuul/4get:latest
```

...Or with SSL:

```
docker run -d -p 443:443 -e FOURGET_SERVER_NAME="4get.ca" -e FOURGET_PROTO="https" -v /etc/letsencrypt/live/domain.tld:/etc/4get/certs  luuul/4get:latest
```
