Programmatically (manually) creating Configurable Magento 2 Product - magento2

Question

Programmatically (manually) creating Configurable Magento 2 Product :
The Product are generated correctly, but I am facing issue with, not generating product Configuration Details.
This Configuration details will help to generate the relation between Configurable product and associate Child Products, these part not working while programmatically create the Product.
Please suggest solution for this issue.
Please find my below code:

Answer 1

must be done by product repository
working code below
ids of simples are defined here: $associatedProductIds=array(2042, 2044);
attribute is color, must be in default attribute set, can be more then 1 if you duplicate attributeValues array and add it here:
$configurableAttributesData = []
$ob = ObjectManager::getInstance();
/** #var $installer \Magento\Catalog\Setup\CategorySetup */
$installer = $ob->create('Magento\Catalog\Setup\CategorySetup');
/** #var ProductRepositoryInterface $productRepository */
$productRepository = $ob->create(ProductRepositoryInterface::class);
/** #var $installer CategorySetup */
$installer = $ob->create(CategorySetup::class);
/* Create simple products per each option value*/
/** #var AttributeOptionInterface[] $options */
$attributeSetId = $installer->getAttributeSetId('catalog_product', 'Default');
$eavConfig = $ob->get('Magento\Eav\Model\Config');
$attribute = $eavConfig->getAttribute('catalog_product', 'color');
$options = $attribute->getOptions();
array_shift($options); //remove the first option which is empty
$attributeValues = [];
foreach ($options as $option) {
$attributeValues[] = [
'label' => 'test',
'attribute_id' => $attribute->getId(),
'value_index' => $option->getValue(),
];
}
$associatedProductIds=array(2042, 2044);
/** #var Factory $optionsFactory */
$optionsFactory = $ob->create(Factory::class);
$configurableAttributesData = [
[
'attribute_id' => $attribute->getId(),
'code' => $attribute->getAttributeCode(),
'label' => $attribute->getStoreLabel(),
'position' => '0',
'values' => $attributeValues,
],
];
/** #var $product Product */
$product = $ob->create(Product::class);
$configurableOptions = $optionsFactory->create($configurableAttributesData);
$extensionConfigurableAttributes = $product->getExtensionAttributes();
$extensionConfigurableAttributes->setConfigurableProductOptions($configurableOptions);
$extensionConfigurableAttributes->setConfigurableProductLinks($associatedProductIds);
$product->setExtensionAttributes($extensionConfigurableAttributes);
$product->setTypeId(Configurable::TYPE_CODE)
->setAttributeSetId($attributeSetId)
->setWebsiteIds([1])
->setName('Connewfcolor')
->setSku('configcolor')
->setVisibility(Visibility::VISIBILITY_BOTH)
->setStatus(Status::STATUS_ENABLED)
->setStockData(['use_config_manage_stock' => 1, 'is_in_stock' => 1]);
$productRepository->save($product);
