The official Symfony 4 advice is to autowire only what you need. So instead of injecting ContainerInterface and requesting an EntityManager from that, inject EntityManagerInterface directly:

use Doctrine\ORM\EntityManagerInterface;

class YourCommand extends Command
{

    private $em;

    public function __construct(EntityManagerInterface $em)
    {
        parent::__construct();
        $this->em = $em;
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $this->em->persist($thing);
        $this->em->flush();
    }

}
