Infrastructure-Related Configuration Parameters

Infrastructure-related configuration parameters are stored in the config/parameters.yml file and grouped in the following way:

• The database_ parameters are used to connect to the database.

• The mailer_ parameters define settings used to deliver emails sent by the application.

• The websocket_ parameters define settings for the web UI.

• The search_ parameters are used to connect to the search engine.

• The website_search_engine_index_prefix index prefix for website search engine.

• The web_backend_prefix URL prefix for the back-office.

• The session_handler value specifies the PHP session handler to be used.

• The secret value is used to generate CSRF tokens.

• The installed parameter identifies the project ready state:

  • null — The project is not installed or requires reinstallation.
  • 2021-07-08T17:30:36+03:00 — The project is installed.

• The assets_version parameter is used to bust the cache on assets by globally adding a query parameter to all rendered asset paths.

• The assets_version_strategy value defines the strategy used to generate the global assets version. The available values are:

  • null — The asset’s version stays unchanged.
  • time_hash — A hash of the current time.
  • incremental — The next asset’s version is the previous version incremented by one (e.g. ver1 -> ver2 or 1 -> 2).

• The enterprise_licence value defines the project enterprise licence.

• The message_ parameters are used to connect to the message queue transport.

• The enable_price_sharding value enables price list sharding.

• The deployment_type value defines the type of the environment where the project was deployed.

• The liip_imagine.jpegoptim.binary path to the LiipImagineBundle: JpegOptimPostProcessor library.

• The liip_imagine.pngquant.binary path to the LiipImagineBundle: PngquantPostProcessor library.

Default Configuration Values

Default configuration options for the Oro application are defined in the config/parameters.yml.dist file. Some options have inline values, others refer to environment variables, therefore they can be set and changed in runtime without application cache rebuild. Default values for environment variables are provided at the end of the config/parameters.yml files, with the parameter names in a format env(ENVIRONMENT_VARIABLE_NAME).

parameters:
    database_driver:        pdo_mysql
    database_host:          '%env(ORO_DB_HOST)%'

Environment Variables

An environment variable is a variable whose value is set outside the application, typically through a functionality built into the operating system. You can find the list of all the infrastructure-related environment variables available in the application in the config/parameters.yml file.

In the above parameters.yml file example, the database_driver parameter value is provided directly in the YAML file and cannot be changed in runtime without the application cache rebuild, while the database_host parameter can be set in runtime by the environment variable named ORO_DB_HOST.

The default value for the ORO_DB_HOST environment variable is provided at the end of the file and is set to 127.0.0.1. It is used when the environment variable ORO_DB_HOST is not provided.

Warning

Environment variables are always string and are not cast automatically to integer, null, or other types. You should never pass an empty environment variable, like ‘ORO_DB_HOST=’ or ‘ORO_DB_HOST=NULL’. Instead, it should never be available (never be set).
