Help

The debug:container command displays all configured public services:

  php bin/console debug:container

To see deprecations generated during container compilation and cache warmup, use the --deprecations option:

  php bin/console debug:container --deprecations

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

  php bin/console debug:container validator

To get specific information about a service including all its arguments, use the --show-arguments flag:

  php bin/console debug:container validator --show-arguments

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

  php bin/console debug:container --types

To see environment variables used by the container, use the --env-vars flag:

  php bin/console debug:container --env-vars

Display a specific environment variable by specifying its name with the --env-var option:

  php bin/console debug:container --env-var=APP_ENV

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

By default, internal services are hidden. You can display them
using the --show-hidden flag:

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