Laravel Storage misconfiguration when using docker

[recursivetree]

Problem

When using the Storage(https://laravel.com/docs/6.x/filesystem) fascade provided by laravel, the current configuration stores the files in the docker container, meaning the files are lost after an update of the container. This issue came up with recursivetree/seat-info#2.

Expected

The files should be persistent.

Proposed fix

make the directory of the default disk a volume in the docker-compose, so the data is stored outside the docker container.
