Volumes

• /data: Contains assets, extensions and storage

⚠️ Note that the volume should be owned by the user/group with the specified PUID and PGID. If you don't give the volume correct permissions, the container may not start.

Ports

• 8000: HTTP port

Usage

Docker Compose

Docker compose is the recommended way to run this image. You can use the following docker compose template, then run the container:

docker-compose up -d
docker-compose logs -f

Command line

You can also use the following minimal command:

docker run -d -p 8000:8000 --name flarum \
  -v $(pwd)/data:/data \
  -e "DB_HOST=db" \
  -e "FLARUM_BASE_URL=http://127.0.0.1:8000" \
  crazymax/flarum:latest

-e "DB_HOST=db"
⚠️ db must be a running MySQL instance

Upgrade

You can upgrade Flarum automatically through the UI, it works well. But I recommend to recreate the container whenever I push an update:

docker-compose pull
docker-compose up -d

Notes

First launch

On first launch, an initial administrator user will be created:

Manage extensions

You can install Flarum extensions from the command line using a specially crafted script with this image:

docker-compose exec flarum extension require <package>

To remove an extension:

docker-compose exec flarum extension remove <package>

To list all extensions:

docker-compose exec flarum extension list

Example with fof/upload extension:

$ docker-compose exec flarum extension require fof/upload
