Service of type Nette\Database\Connection not found

Hello, i am using \Nette\DI and \Nette\Database\Connection

i have container like this:

class Container extends \Nette\DI\Container
{
    public function __construct(array $params = [])
    {
        parent::__construct($params);
    }

    function createServiceDatabase(): \Nette\Database\Connection
    {
        return new \Nette\Database\Connection(
            $this->parameters['dsn'],
            $this->parameters['user'],
            $this->parameters['password']
        );
    }
}

My app is parsing url to call method doWorld in this class:

namespace Command;
class Hello extends BaseCommand
{
    public function doWorld(\Nette\Database\Connection $db)
    {
        $db->query("INSERT INTO hello_world",["example_column"=>"hello world"]);
    }
}

and i want it call like this:

$Class = new \Command\Hello();
$container->callMethod([$Class,"doWorld"]);

but it throws error

Service of type Nette\Database\Connection needed by $db in Command\Hello::doWorld() not found. Did you register it in configuration file?

I don't know how to fix it, because when i do this:

//This returns Nette\Database\Connection
Debugger::barDump($container->getService("database"));
//This throws "Service of type Nette\Database\Connection not found."
Debugger::barDump($container->getByType("\Nette\Database\Connection"));

Why?

Is the container generated by compiler or did you extend container and wrote createServiceDatabase() method by your own? Because for getByType() you need also mapping in $wiring property

Container is meant to be always generated, writing it by your own is waste of time. But generating is quite complex (see here)
So I suggest you to use nette/bootstrap and register services in neon instead.
Here and here is the example how to use it.

Okay, i created container with nette/bootstrap and it works like it should, thank you.
