Is there a way for a block service to get the page ID from which it is being called?

Question

In my Symfony 3.3 application, I have built a block service using SonataBlockBundle. Now I want to pull some other field values from the page on which the block lives. In other words, I want to do something like this:

public function configureSettings(OptionsResolver $resolver)
{
    $pageRepository = $this->doctrine->getRepository('ApplicationSonataPageBundle:Page');

    $pageId = someMagicalMethodCall();

    $page = $repository->findOneBy(['id' => $pageId]);
    $images = $page->getImageUrls;
    $resolver->setDefaults(array(
        'content' => 'Some custom content',
        'images' => $images,
        'template' => 'AppBundle:Block:block_media.html.twig',
    ));
}

Is this possible? If so, what would I put in place of someMagicalMethodCall in the block above?

Thanks to Jakub Krawczyk and a mentor, I found this page:

Getting instance of container in custom sonata block

... which led me to another way of getting the page related to a block, from within the execute() method. So I now have the following code, which serves me well:

public function execute(BlockContextInterface $blockContext, Response $response = null)
{
    $page = $blockContext->getBlock()->getPage();
    $localImages = $page->getImages();
    $imageProvider = $this->provider;
    foreach ($localImages as $key => $image) {
        $publicImages[$key]['url'] = $imageProvider->generatePublicUrl($image, 'reference');
        $publicImages[$key]['name'] = $image->getName();
    }
    $settings = $blockContext->getSettings();
    $settings['images'] = $publicImages;
    return $this->renderResponse($blockContext->getTemplate(), array(
        'block' => $blockContext->getBlock(),
        'settings' => $settings,
    ), $response);
}

Again, thanks to all involved.
