Import configuration settings

When you set up a production system using the Commerce 2.2 pipeline deployment model, you must import configuration settings from config.php and env.php into the database.
These settings include configuration paths and values, websites, stores, store views, and themes.

After importing websites, stores, store views, and themes, you can create product attributes and apply them to websites, stores, and store views, on the production system.

Import command

On your production system, run the following command to import data from the configuration files (config.php and env.php) to the database:

bin/magento app:config:import [-n, --no-interaction]

Use the optional [-n, --no-interaction] flag to import data without any interaction.

If you enter bin/magento app:config:import without the optional flag, you are required to confirm the changes.

For example, if configuration file contains one new website and one new store, the following message is displayed:

These Websites will be created: New Website
These Groups will be created: New Store
Do you want to continue [yes/no]?

To continue the import, enter yes.

If deployment configuration files contain some data to import, a message similar to the following is displayed:

Start import:
Some information about importing

If deployment configuration files do not contain any data to import, a message similar to the following is displayed:

Start import:
Nothing to import

What we import

The following sections discuss in detail what data we import.

System configuration

Commerce directly uses values in the system array in the config.php or env.php files instead of importing them into the database because they require some pre- and post-processing actions.

For example, the value of the configuration path web/secure/base_url must be validated with backend models.

Backend models

Backend models are the mechanism for processing changes in system configuration.
You define backend modules in <module_name>/adminhtml/system.xml.

All backend models must extend the Magento\Framework\App\Config\Value class.

When we import backend models, we do not save the configuration values.

Websites, stores, and store groups configuration

We import the following types of configurations.
(These configurations are under the scopes array in config.php.)

The preceding configurations can be imported in the following modes:

Theme configuration

Theme configuration includes all themes registered in your Commerce system; the data comes directly from the theme database table. (Theme configuration is in the themes array in config.php.)

Structure of theme data

The key of array is full theme path: area + theme path

For example, frontend/Magento/luma.
frontend is area and Magento/luma is theme path.

The value of array is data about theme: code, title, path, parent id

Full example:

'frontend/Magento/luma' =>
   array (
      'parent_id' => 'Magento/blank',
      'theme_path' => 'Magento/luma',
      'theme_title' => 'Magento Luma',
      'is_featured' => '0',
      'area' => 'frontend',
      'type' => '0',
      'code' => 'Magento/luma',
),
