Odoo/docker documentation on Docker Hub missing critical step for simple example - style sheets missing is common result

The base example in the odoo docker docs is missing a required step:

Start a PostgreSQL server
$ docker run -d -e POSTGRES_USER=odoo -e POSTGRES_PASSWORD=odoo -e POSTGRES_DB=postgres --name db postgres:10
Start an Odoo instance
$ docker run -p 8069:8069 --name odoo --link db:db -t odoo

Should be

Start a PostgreSQL server
$ docker run -d -e POSTGRES_USER=odoo -e POSTGRES_PASSWORD=odoo -e POSTGRES_DB=postgres --name db postgres:10
Create a volume for web data
$ docker create odoo-web-data
Start an Odoo instance
$ docker run -p 8069:8069 --name odoo -v odoo-web-data:/var/lib/odoo --link db:db -t odoo

Running the single image version of odoo without a volume for web data will lose stylesheets any other content in the filestore that is generated at initial DB creation and bootstrap if the container is removed cleaned up.

The fix is simple- add a step to create the odoo-web-data volume, and then mounting it to the docker run command.

When the volume is not present, a recycling of the odoo image will lose filestore data, and stylesheets will 404 when the frontend tries to retrieve them.

Start with the Docker Hub base example described in the issue and compare its PostgreSQL and Odoo commands with the proposed version. Done means the example creates the odoo-web-data volume and mounts it at /var/lib/odoo so filestore data and stylesheets persist when the Odoo container is recycled.
