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

Detailed Info about a Single Service
