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).

docker-compose up -d

Fill out the installation form :

• Your admin password must contain at least 8 characters.
• You can't use MariaDB 10.2 or 10.3 for the moment. More information on this issue here.
• 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.

Click on Install Flarum and after few seconds the forum homepage should appear.
