# Install guide for Docker
#### 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:
```
docker run -d -p 80:80 -e FOURGET_SERVER_NAME="4get.ca" luuul/4get:latest
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 -v /etc/letsencrypt/live/domain.tld:/etc/4get/certs -e FOURGET_SERVER_NAME="4get.ca" luuul/4get:latest
```
if the certificate files are not mounted to /etc/4get/certs the service listens to port 80
the certificate directory expects files named `fullchain.pem` and `privkey.pem`
# Install using Docker Compose
copy `docker-compose.yaml`
to serve custom banners create a directory named `banners` for example with images and mount to `/var/www/html/4get/banner`
to serve captcha images create a directory named `captchas` for example containing subfolders with images and mount to `/var/www/html/4get/data/captcha`
any environment variables prefixed with `FOURGET_` will be added to the generated config
the entrypoint will automatically set the `CAPTCHA_DATASET` value for you based on directory names and number of files in each
to set `INSTANCES` pass a comma separated string of urls (FOURGET_INSTANCES = "https://4get.ca,https://domain.tld")
```
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
```
#### With Docker Compose
Replace relevant values and start with `docker compose up -d`
##### HTTP
```
# docker-compose.yaml
version: "3.7"
services:
fourget:
image: luuul/4get:latest
restart: always
restart: unless-stopped
environment:
- FOURGET_VERSION=6
- FOURGET_PROTO=http
- FOURGET_SERVER_NAME=4get.ca
ports:
- "80:80"
```
##### HTTPS
```
# docker-compose.yaml
version: "3.7"
services:
fourget:
image: luuul/4get:latest
restart: unless-stopped
environment:
- FOURGET_VERSION=6
- FOURGET_PROTO=https
- FOURGET_SERVER_NAME=4get.ca
ports:
- "80:80"
- "443:443"
volumes:
- /etc/letsencrypt/live/domain.tld:/etc/4get/certs
- ./banners:/var/www/html/4get/banner
- ./captchas:/var/www/html/4get/data/captcha
```
Replace relevant values and start with `docker compose up -d`
##### Captcha Enabled
Set `FOURGET_BOT_PROTECTION=1` and mount a directory containing captcha files to `/var/www/html/4get/data/captcha`
```
# docker-compose.yaml
version: "3.7"
services:
fourget:
image: luuul/4get:latest
restart: unless-stopped
environment:
- FOURGET_VERSION=6
- FOURGET_PROTO=http
- FOURGET_SERVER_NAME=4get.ca
- FOURGET_BOT_PROTECTION=1
ports:
- "80:80"
volumes:
- ./captcha:/var/www/html/4get/data/captcha
```
##### Custom Banners
```
# docker-compose.yaml
version: "3.7"
services:
fourget:
image: luuul/4get:latest
restart: unless-stopped
environment:
- FOURGET_VERSION=6
- FOURGET_PROTO=http
- FOURGET_SERVER_NAME=4get.ca
ports:
- "80:80"
volumes:
- ./banners:/var/www/html/4get/banner
