I want to reindex all indexes in Magento2 from an external file, for this I created a external file as below :

...

    $indexers = $objectManager->get('MagentoFrameworkIndexerConfigInterface')->getIndexers();

    foreach($indexers as $indexer)

    {

        $actualIndexer = $objectManager->get('MagentoFrameworkIndexerIndexerInterface')->load($indexer['indexer_id']);

        $actualIndexer->reindexAll();

    }



... 

When I run it on then only config index reindexed, not all.

I know it is not a good way to reindex but It is my custom module requirement, I want to integrate reindex code in my module save controller, so that when client save form there will be no indexing issue.

How to reindex all indexes?

Try below code :

/**

 * @var MagentoIndexerModelIndexerFactory

 */

protected $_indexerFactory;

/**

 * @var MagentoIndexerModelIndexerCollectionFactory

 */

protected $_indexerCollectionFactory;



public function __construct(

    MagentoIndexerModelIndexerFactory $indexerFactory,

    MagentoIndexerModelIndexerCollectionFactory $indexerCollectionFactory

){

   $this->_indexerFactory = $indexerFactory;

   $this->_indexerCollectionFactory = $indexerCollectionFactory;

}



// you can call this function to do reindexing

public function reIndexing(){

   $indexerCollection = $this->_indexerCollectionFactory->create();

   $ids = $indexerCollection->getAllIds();

   foreach ($ids as $id) {

   $idx = $this->_indexerFactory->create()->load($id);

   $idx->reindexAll($id); 

   //$idx->reindexRow($id); 

}

Take a look at MagentoIndexerConsoleCommandIndexerReindexCommand::execute() on how the console command does it. If you analyze the code you can up with something like:

/**

 * @var MagentoIndexerModelIndexerCollectionFactory

 */

protected $indexerCollectionFactory;



/**

 * Foo constructor.

 * @param MagentoIndexerModelIndexerCollectionFactory $collectionFactory

 */

public function __construct(

    MagentoIndexerModelIndexerCollectionFactory $indexerCollectionFactory

) {

    $this->indexerCollectionFactory = $indexerCollectionFactory;

}



/**

 * Run every indexer

 */

public function runEveryIndexer()

{

    $indexerCollection = $this->indexerCollectionFactory->create();

    foreach ($indexerCollection->getItems() as $indexer) {

        $indexer->reindexAll();

    }

}

A small sidenote: I don't know your use case, but it might make more sense to only reindex the required indexers, because some indexers might take a long time to run and are not always required to.

Simply call this function wherever you need to reindex. If you make it static, you can include and call it from anywhere you want, because it is class-independent.

use MagentoIndexerConsoleCommandIndexerReindexCommand;

public function reIndexing()

{

    $obj                      = MagentoFrameworkAppObjectManager::getInstance();

    $indexerCollectionFactory = $obj->get("MagentoIndexerModelIndexerCollectionFactory");

    $indexerFactory           = $obj->get("MagentoIndexerModelIndexerFactory");

    $indexerCollection        = $indexerCollectionFactory->create();

    $allIds                   = $indexerCollection->getAllIds();



    foreach ($allIds as $id)

    {

        $indexer = $indexerFactory->create()->load($id);

        $indexer->reindexAll(); // this reindexes all

    }

}
