How to Debug the Service Container & List Services

Warning: You are browsing the documentation for Symfony 3.x, which is no longer maintained.

Read the updated version of this page for Symfony 7.2 (the current stable version).

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:

        1
        $ php bin/console debug:container
    

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

        1
        $ php bin/console debug:container --show-private
    

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

        1
        $ php bin/console debug:autowiring
    

3.4

The debug:autowiring command was introduced in Symfony 3.3.
