How to Debug the Service Container & List Services
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 app/console debug:container
By default, only public services are shown, but you can also view private services:
$ php app/console debug:container --show-private
If a private service is only used as an argument to just one other service,
it won’t be displayed by the
debug:container command, even when using
--show-private option. See Inline Private Services
for more details.
You can get more detailed information about a particular service by specifying its id:
$ php app/console debug:container app.mailer
