 When the Odoo container is created like described above, the odoo filestore is created inside the container. If the container is removed, the filestore is lost. The preferred way to prevent that is by using a Docker named [volume](https://docs.docker.com/storage/volumes/).

-$ docker run -v odoo-data:/var/lib/odoo -d -p 8069:8069 --name odoo --link db:db -t odoo

 # How to upgrade this image
 
-Odoo images are updated on a regular basis to make them use recent releases (a new release of each version of Odoo is built [every night](http://nightly.odoo.com/)). Please be aware that what follows is about upgrading from an old release to the latest one provided of the same major version, as upgrading from a major version to another is a much more complex process requiring elaborated migration scripts (see [Odoo Enterprise Upgrade page](https://upgrade.odoo.com/database/upload) or this [community project](https://doc.therp.nl/openupgrade/) which aims to write those scripts).
