How to get the catalog price rule programmatically in Magento2

Simply I just want to get the catalog price rules applied to products during checkout. I know a lot of solution is out from some sources for Magento 1, an example is this blog https://jutesenthil.wordpress.com/2015/09/28/get-catalog-rule-by-product-id-in-magento/ but trying to get same result in Magento 2 does not seem to be working. my code snippet is below.

/**
 * @param $productId
 * @param $customerGroupId
 * @return mixed
 */
public function getCatalogPriceRuleFromProduct($productId, $customerGroupId)
{
    /**
     * @var MagentoCatalogModelProductFactory
     */
    $product = $this->_objectManager->create('MagentoCatalogModelProductFactory')->create()->load($productId);

    $storeId = $product->getStoreId();

    $store = $this->_store_manager->getStore($storeId);

    $websiteId = $store->getWebsiteId();

    /**
     * @var MagentoFrameworkStdlibDateTimeDateTime
     */
    $date = $this->_objectManager->create('MagentoFrameworkStdlibDateTimeDateTime');
    $dateTs = $date->gmtDate();

    /**
     * @var MagentoCatalogRuleModelRule
     */
    $resource = $this->_objectManager->create('MagentoCatalogRuleModelRule');
    // $resource = $this->_objectManager->create('MagentoCatalogRuleModelRuleFactory');

    $rules = $resource->getRulesFromProduct($dateTs, $websiteId, $customerGroupId, $productId);
    /*$rules = $resource->getCollection()
        ->addFieldToFilter('from_time', $dateTs)
        ->addFieldToFilter('to_time', $dateTs)
        ->addFieldToFilter('product_id', $productId)
        ->addFieldToFilter('store_id', $storeId)
        ->addFieldToFilter('website_id', $websiteId)
        ->addFieldToFilter('customer_group_id', $customerGroupId);*/

    return $rules;
}

But always returning null.

Any help or ideas to go about this??

    For anyone that requires this solution this is it

    /**
 * @param $productId
 * @param $customerGroupId
 * @return mixed
 */
public function getCatalogPriceRuleFromProduct($productId, $customerGroupId)
{
    /**
     * @var MagentoCatalogModelProductFactory
     */
    $product = $this->_objectManager->create('MagentoCatalogModelProductFactory')->create()->load($productId);

    $storeId = $product->getStoreId();
    $store = $this->_store_manager->getStore($storeId);
    $websiteId = $store->getWebsiteId();
    /**
     * @var MagentoFrameworkStdlibDateTimeDateTime
     */
    $date = $this->_objectManager->create('MagentoFrameworkStdlibDateTimeDateTime');
    $dateTs = $date->gmtDate();

    /**
     * @var MagentoCatalogRuleModelResourceModelRule
     */
    $resource = $this->_objectManager->create('MagentoCatalogRuleModelResourceModelRule');

    $rules = $resource->getRulesFromProduct($dateTs, $websiteId, $customerGroupId, $productId);

    return $rules;
}

    and if you need to get the actual discount amount just use this piece of code as well.

    /**
                     * @var MagentoCatalogRuleModelRuleFactory
                     */
                    $rule = $this->_objectManager->create('MagentoCatalogRuleModelRuleFactory')->create();
                    $discountAmount = $rule->calcProductPriceRule($product,$product->getPrice());

    All thanks to @Pallavi

    For getting all rules applied in your cart:

    Class <your classname>
{
protected $_item;

public function __construct(
    ...
    MagentoQuoteModelQuoteItem $item
    ...
) {
    ...
    $this->_item = $item;
    ...
}

public function GetAppliedRulesDetails() {
         $appliedIds = $this->_item->getAppliedRuleIds();
         /* here you need to load the results ids and get required details */
         }

}

    You can check vendor/magento/module-sales-rule/Observer/SalesOrderAfterPlaceObserver.php file for looping through rules.

    What I see in your code is , you are trying to call $resource->getRulesFromProduct() and your class is MagentoCatalogRuleModelRule. Try calling MagentoCatalogRuleModelResourceModelRule instead. This should work!
