How to setup Flarum in Docker

To begin

Pull from hub.docker.com
docker pull mondedie/flarum:latest

or build it manually
docker build -t mondedie/flarum:latest https://github.com/mondediefr/docker-flarum.git

Next setup the docker-compose.yml

version: "3"
services:

environment:
- MYSQL_ROOT_PASSWORD=xxxxxxxxxx
- MYSQL_DATABASE=flarum

Customise the MYSQL settings to your setup!

Create a environment file (see docker-compose: /mnt/docker/flarum/flarum.env)

nano /mnt/docker/flarum/flarum.env
