 to run an application with the ``prod`` config (``kernel.environment``) in different
 scenarios like ``staging`` or ``production`` (``kernel.runtime_environment``).

 ``kernel.runtime_mode``
 -----------------------

 **type**: ``string`` **default**: ``%env(query_string:default:container.runtime_mode:APP_RUNTIME_MODE)%``

 This parameter stores a query string of the current runtime mode used by the
 application. For example, the query string looks like ``web=1&worker=0`` when
 the application is running in web mode and ``web=1&worker=1`` when running in
 a long-running web server. This parameter can be set by using the
 ``APP_RUNTIME_MODE`` env var.

 .. versionadded:: 6.4

    The ``kernel.runtime_mode`` parameter was introduced in Symfony 6.4.

 ``kernel.runtime_mode.web``
 ---------------------------

 **type**: ``boolean`` **default**: ``%env(bool:default::key:web:default:kernel.runtime_mode:)%``

 Whether the application is running in a web environment.

 .. versionadded:: 6.4

    The ``kernel.runtime_mode.web`` parameter was introduced in Symfony 6.4.

 ``kernel.runtime_mode.cli``
 ---------------------------

 **type**: ``boolean`` **default**: ``%env(not:default:kernel.runtime_mode.web:)%``

 Whether the application is running in a CLI environment. By default,
 this value is the opposite of the ``kernel.runtime_mode.web`` parameter.

 .. versionadded:: 6.4

    The ``kernel.runtime_mode.cli`` parameter was introduced in Symfony 6.4.

 ``kernel.runtime_mode.worker``
 ------------------------------

 **type**: ``boolean`` **default**: ``%env(bool:default::key:worker:default:kernel.runtime_mode:)%``

 Whether the application is running in a worker/long-running environment. Not all web
 servers support it, and you have to use a long-running web server like `FrankenPHP`_.

 .. versionadded:: 6.4

    The ``kernel.runtime_mode.worker`` parameter was introduced in Symfony 6.4.

 ``kernel.secret``
