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)

# 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

docker-compose up -d mariadb
# Wait a moment for the creation of the database
docker-compose up -d flarum

• ⚠️ 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.
