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)

# 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

• ⚠️ 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.

Upgrade to v0.1.0-beta.8 from v0.1.0-beta.7.2

⚠️ Backup your database, config.php, composer.lock and assets folder
⚠️ Disable all 3rd party extensions prior to upgrading in panel admin.

1 - Add installed.txt file in assets folder
Make sure to mount your assets folder with the folder /flarum/app/public/assets

touch /mnt/docker/flarum/assets/installed.txt
chown UID:GID /mnt/docker/flarum/assets/installed.txt

2 - Create your own environment file

# 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

# environment variable not required
#FLARUM_ADMIN_USER=admin
#FLARUM_ADMIN_PASS=xxxxxxxxxx
#FLARUM_ADMIN_MAIL=admin@domain.tld
#FLARUM_TITLE=Test flarum

chown UID:GID /mnt/docker/flarum/flarum.env

3 - Update your docker-compose file, see an example here

4 - Pull the last docker images

docker pull mondedie/docker-flarum:0.1.0-beta.8-stable
docker-compose stop flarum
docker-compose rm flarum
docker-compose up -d

5 - Updating your database and removing old assets: (container_flarum is the name of your container)

docker exec -ti flarum php /flarum/app/flarum migrate
docker exec -ti flarum php /flarum/app/flarum cache:clear

Since the flarum-english extension has been renamed to flarum-lang-english, you'll need to to re-enable it from the admin panel.
After that your upgrade is finish. 🎉 🎉

Upgrade to v0.1.0-beta.7.2 from v0.1.0-beta.6

⚠️ Disable 3rd party extensions prior to upgrading.

docker pull mondedie/docker-flarum:0.1.0-beta.7.2-stable
