Answer 1

In Symfony 4 I could not get $this->getContainer()->get('templating')->render($view, $parameters); to work.

I set the namespace use for Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand and extended ContainerAwareCommand class EmailCommand extends ContainerAwareCommand

I get an exception thrown

[Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException]
      You have requested a non-existent service "templating".

For Symfony 4, this is the solution I came up with.

First I installed Twig.

composer require twig

Then created my own twig service.

getProjectDir());

        parent::__construct($loader);
    }
}

Now my email command looks like this.

mailer = $mailer;
        $this->twig = $twig;

        parent::__construct();
    }

    protected function configure() {
        $this->setDescription('Email bot.');
    }

    protected function execute(InputInterface $input, OutputInterface $output) {

        $template = $this->twig->load('templates/email.html.twig');

        $message = (new \Swift_Message('Hello Email'))
            ->setFrom('emailbot@domain.com')
            ->setTo('someone@somewhere.com')
            ->setBody(
                $template->render(['name' => 'Fabien']),
                'text/html'
            );

        $this->mailer->send($message);
    }
}
