Technical details

This topic discusses technical implementation details about pipeline deployment in Commerce 2.2 and later. Improvements can be divided into the following areas:

This topic also discusses the recommended workflow for pipeline deployment and provides some examples to help you understand how it works.

Before you get started, review the Prerequisites for your development, build, and production systems.

Configuration management

To enable you to synchronize and maintain the configuration of your development and production systems, use the following override scheme.

As the diagram shows, the configuration values are used in the following order:

Manage the shared configuration

The shared configuration is stored in app/etc/config.php, which should be in source control.

Set the shared configuration in the Admin in your development (or ÃÛ¶¹ÊÓƵ Commerce on cloud infrastructure integration) system and write the configuration to config.php using the magento app:config:dump command.

Manage the system-specific configuration

The system-specific configuration is stored in app/etc/env.php, which should not be in source control.

Set the system-specific configuration in the Admin in your development (or ÃÛ¶¹ÊÓƵ Commerce on cloud infrastructure integration) system and write the configuration to env.php using the magento app:config:dump command.

This command also writes sensitive settings to env.php.

Manage the sensitive configuration

The sensitive configuration is also stored in app/etc/env.php.

You can manage the sensitive configuration in any of the following ways:

Configuration settings locked in the Admin

Any configuration settings in config.php or env.php are locked in the Admin; that is, those settings cannot be changed in the Admin.
Use the magento config:set or magento config:set --lock command to change the settings in the config.php or env.php files.

The Commerce Admin

The Admin exhibits the following behavior while in production mode:

Install and remove cron

In version 2.2 for the first time, we help you set up your cron job by providing the magento cron:install command. This command sets up a crontab as the user who runs the command.

Also, you can remove the crontab using the magento cron:remove command.

Recommended pipeline deployment workflow

The following diagram shows how we recommend you use pipeline deployment to manage the configuration.

Development system

On your development system, you make configuration changes in the Admin and generate the shared configuration, app/etc/config.php and the system-specific configuration, app/etc/env.php. Check Commerce code and the shared configuration into source control and push it to the build server.

You should also install extensions and customize Commerce code on the development system.

On your development system:

After running the commands to clear the assets, Commerce generates working files.

Build system

The build system compiles code and generates static view files for themes registered in Commerce. It does not need a connection to the Commerce database; it needs only the Commerce codebase.

On your build system:

Production system

On your production system (that is, your live store) you pull generated assets and code updates from source control and set system-specific and sensitive configuration settings using the command line or environment variables.

On your production system:

Configuration management commands

We provide the following commands to help you manage the configuration:

Configuration management examples

This section shows examples of managing the configuration so you can see how changes are made to config.php and env.php.

Change the default locale

This section shows the change made to config.php when you change the default weight unit using the Admin (Stores > Settings > Configuration > General > General > Locale Options).

After you make the change in the Admin, run bin/magento app:config:dump to write the value to config.php. The value is written to the general array under locale as the following snippet from config.php shows:

'general' =>
    array (
        'locale' =>
        array (
            'code' => 'en_US',
            'timezone' => 'America/Chicago',
            'weight_unit' => 'kgs'
        )
    )

Change several configuration settings

This section discusses making the following configuration changes:

After you make the change in the Admin, run bin/magento app:config:dump on your development system. This time, not all of your changes are written to config.php; in fact, only the website, store, and store view are written to that file as the following snippets show.

config.php

config.php contains:

websites array:

      'new' =>
      array (
        'website_id' => '2',
        'code' => 'new',
        'name' => 'New website',
        'sort_order' => '0',
        'default_group_id' => '2',
        'is_default' => '0',
      ),

groups array:

      2 =>
      array (
        'group_id' => '2',
        'website_id' => '2',
        'code' => 'newstore',
        'name' => 'New store',
        'root_category_id' => '2',
        'default_store_id' => '2',
      ),

stores array:

     'newview' =>
      array (
        'store_id' => '2',
        'code' => 'newview',
        'website_id' => '2',
        'group_id' => '2',
        'name' => 'New store view',
        'sort_order' => '0',
        'is_active' => '1',
      ),

payment array:

      'payment' =>
      array (
        'paypal_express' =>
        array (
          'active' => '0',
          'in_context' => '0',
          'title' => 'PayPal Express Checkout',
          'sort_order' => NULL,
          'payment_action' => 'Authorization',
          'visible_on_product' => '1',
          'visible_on_cart' => '1',
          'allowspecific' => '0',
          'verify_peer' => '1',
          'line_items_enabled' => '1',
          'transfer_shipping_options' => '0',
          'solution_type' => 'Mark',
          'require_billing_address' => '0',
          'allow_ba_signup' => 'never',
          'skip_order_review_step' => '1',
        ),

env.php

The default email domain system-specific configuration setting is written to app/etc/env.php.

The PayPal settings are written to neither file because the bin/magento app:config:dump command does not write sensitive settings. You must set the PayPal settings on the production system using the following commands:

bin/magento config:sensitive:set paypal/wpp/api_username <username>

bin/magento config:sensitive:set paypal/wpp/api_password <password>
