#### 3 - Run it
You need a reverse proxy to access flarum, this is not described here. You can use the solution of your choice (Traefik, Nginx, Apache, Haproxy, Caddy, H2O...etc).
Create a environment file (see docker-compose: /mnt/docker/flarum/flarum.env [here](https://github.com/mondediefr/docker-flarum/tree/master#2---docker-composeyml))
```
# vi /mnt/docker/flarum/flarum.env
DEBUG=false
FORUM_URL=http://domain.tld
# Database configuration
DB_HOST=mariadb
DB_NAME=flarum
DB_USER=flarum
DB_PASS=xxxxxxxxxx
DB_PREF=flarum_
DB_PORT=3306
# User admin flarum (environment variable for first installation)
# /!\ admin password must contain at least 8 characters /!\
FLARUM_ADMIN_USER=admin
FLARUM_ADMIN_PASS=xxxxxxxxxx
FLARUM_ADMIN_MAIL=admin@domain.tld
FLARUM_TITLE=Test flarum
```
Run your docker-compose
```sh
docker-compose up -d mariadb
# Wait a moment for the creation of the database
docker-compose up -d flarum
```
* :warning: Your admin password must contain at least **8 characters** (FLARUM_ADMIN_PASS).
* If you get an error 500 with _Something went wrong_ message, switch the `DEBUG` environment variable to `true` to see the actual error message in your browser.

services:

- PHP_EXTENSIONS=gmp session brotli
volumes:
- /mnt/docker/flarum/assets:/flarum/app/public/assets
