Symfony List of all kernel parameters available like %kernel.debug%

Question

How can I get a list of all kernel parameters that are available for use in my configuration files. E.g., in config.yml I know I can access %kernel.debug% which either returns true or false depending on AppKernel's initialization in the app.php (or app_dev.php) file.

>=3.0 (or lower if using 3.0 directory structure)

List all parameters in the container
php bin/console debug:container --parameters

For *nix use grep to limit results
php bin/console debug:container --parameters | grep kernel

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