How it works...

At start up, Odoo loads its configuration in three passes. First, a set of default values for all options is initialized from the source code, then the configuration is parsed, and any value defined in the file overrides the defaults. Finally, the command-line options are analyzed and their values override the configuration obtained from the previous pass.

As mentioned earlier, the names of the configuration variables can be found from the names of the command-line options by removing the leading dashes and converting the middle dashes to underscores. There are a few exceptions, notably the following:

Here's a list of options commonly set through the configuration file:

The parsing of the configuration file by Odoo is now using the Python ConfigParser module. However, the implementation in Odoo 11.0 has changed, and it is no longer possible to use variable interpolation. So, if you are used to defining values for variables from the values of other variables using the %(section.variable)s notation, you will need to change your habits and revert to explicit values.
