Using Symfony 4.2 here.

use Symfony\Component\Console\Command\Command;
use Doctrine\DBAL\Connection;

class ArchiveCommand extends Command
{
   protected static $defaultName = 'simon:test:archive';
   private $connection;

   public function __construct(Connection $connection)
   {
      $this->connection = $connection;
      parent::__construct();
   }

   /**
   * {@inheritdoc}
   */
   protected function execute(InputInterface $input, OutputInterface $output)
   {
      $this->connection->prepare('SQL HERE');
   }

Works exactly as getting it from the container but is deprecated using it from the containerAwareInterface and should be injected now.
