FileBin 🐋

A docker image for FileBin to have it up and running in seconds.

Visit project on GitHub.

Getting started

Recommended way is to use the example docker-compose.yml file and make yourself familiar with the environment variables which can be set. Defaults should do as a starting point.

Default database is PostgreSQL. Other databases are supported and can be configured via exposed environment variables. Please refer to the original documentation of the application for further details. PHP modules for MySQL are included in the image.

Configuration

After your database and the application docker container is up and running, add a first user by executing a command within the docker container:

docker exec -it filebin_app /bin/sh
php /var/www/index.php user add_user

Persisting volumes

You'll probably want the uploads/ folder to be persistent across container restarts.

Here's an example on how to persist the data/uploads/ folder of the application.

• Create folder: mkdir -p ./filebin_data
• Afterwards, adjust permissions so that the folder can be used within the docker container: chown -R 65534:102 <host-mount> (nobody:nginx)
• Reference the folder as a docker volume, e.g. with ./filebin_data:/var/www/data/uploads

Cron jobs

Application specific cron jobs are run every 15 minutes.

Advanced configuration: customize non-exposed configuration variables

If you need to make frequent changes or adapt configuration values which are not exposed as environment variables, you probably want have the config-local.php and database.php or the entire config/ folder on the hosts file system.

In order to do so, first extract the current configuration, e.g. by extracting only the required .php files or by extracting the entire config/ folder. In this example we'll just use entire folder.

docker cp filebin_app:/var/www/application/config/ ./filebin_config
chown -R 65534:102 ./filebin_config

Add the ./filebin_config folder as a host bind to the application docker container, e.g. with ./filebin_config:/var/www/application/config/

Available environment variables

Please have a look into Dockerfile for available environment variables, they're all exposed there.

All variables to FileBin itself should be self-explaining. You should also be familiar with the php.ini variables. They're only inserted on build, if you like to increase the file limit above the used php variable values of this image, you'll need to rebuild the docker image.

There are two environment variables introduced by this image:

• RECONFIGURE: If all defined environment should be re-applied to the provided .tpl files within the image. You probably want this to be 1 unless you mounted your config/ folder on the host
• MIGRATE: Calls FileBin database migration every time the container is started and updates dependencies via composer

Setting up a nginx proxy

Be sure to set the environment variable BASE_URL to the same where you expose it, e.g. BASE_URL=https://fb.domain.tld.

An example nginx configuration might look like the following.

upstream filebin {
    server 127.0.0.1:181;
}

server {
    listen 80;
    server_name  fb.domain.tld;
    return 301 https://fb.domain.tld$request_uri;
}

server {
    listen 443 ssl;
    server_name  fb.domain.tld;

    ssl_certificate /etc/letsencrypt/live/fb.domain.tld/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/fb.domain.tld/privkey.pem;

    gzip on;
    access_log off;

    location / {
        proxy_redirect off;
        proxy_pass http://filebin;

        proxy_set_header  Host                $http_host;
        proxy_set_header  X-Real-IP           $remote_addr;
        proxy_set_header  X-Forwarded-Ssl     on;
        proxy_set_header  X-Forwarded-For     $proxy_add_x_forwarded_for;
        proxy_set_header  X-Forwarded-Proto   $scheme;
        proxy_set_header  X-Frame-Options     SAMEORIGIN;

        client_max_body_size        100m;
        client_body_buffer_size     128k;

        proxy_buffer_size           4k;
        proxy_buffers               4 32k;
        proxy_busy_buffers_size     64k;
        proxy_temp_file_write_size  64k;
    }
}

Updates

Just use a newly released image version. Configuration should be compatible.

Backup

Backup the host binds for uploads/ and the database manually.

If you're using the provided docker-compose.yml file you probably can do something like the following and afterwards backup the extracted file from /tmp of your host system:

docker exec filebin_db bash -c "/usr/bin/pg_dumpall -U fb|gzip -c > /filebin_db.sql.gz";
docker cp filebin_db/:/var:/filebin_db.sql.gz /tmp/;
docker exec filebin_db bash -c "rm /filebin_db.sql.gz";
