By default, the Odoo container runs with the Community edition add-ons. If you want to run Odoo with your own add-on modules, you can do this by mounting your add-ons in the /mnt/extra-addons directory as follows:

$ docker run -v /path/to/my_addons:/mnt/extra-addons -p 8069:8069 --name odoo --link db:db -t odoo
