Help

The debug:container command displays all configured public services:

  php bin/console debug:container

To get specific information about a service, specify its name:

  php bin/console debug:container validator

To see available types that can be used for autowiring, use the --types flag:

  php bin/console debug:container --types

By default, private services are hidden. You can display all services by
using the --show-private flag:

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

Use the --tags option to display tagged public services grouped by tag:

  php bin/console debug:container --tags

Find all services with a specific tag by specifying the tag name with the --tag option:

  php bin/console debug:container --tag=form.type

Use the --parameters option to display all parameters:

  php bin/console debug:container --parameters

Display a specific parameter by specifying its name with the --parameter option:

  php bin/console debug:container --parameter=kernel.debug
