How to Debug the Service Container & List Services

You can find out what services are registered with the container using the console. To show all services and the class for each service, run:

$ php bin/console debug:container

By default, only public services are shown, but you can also view private services:

$ php bin/console debug:container --show-private

To see a list of all of the available types that can be used for autowiring, run:

$ php bin/console debug:autowiring

Detailed Info about a Single Service

You can get more detailed information about a particular service by specifying its id:

$ php bin/console debug:container 'App\Service\Mailer'

# to show the service arguments:
$ php bin/console debug:container 'App\Service\Mailer' --show-arguments
