In the app/code/Bss/AddProductAttribute/registration.php please add the code

                      <?php                                \Magento\Framework\Component\ComponentRegistrar::register(                                              \Magento\Framework\Component\ComponentRegistrar::MODULE,                                '                    Bss_AddProductAttribute'                      ,                                __DIR__                                );

In the app/code/Bss/AddProductAttribute/composer.json create as below:

                      {                                "name": "bss/add                                product                                attribute",                                "description": "Bss Add                                              Product                                              Attribute",                                "require": {                                                                "php": "~5.6.0|7.0.2|~7.0.6"                                },                                "type": "magento2-module",                                "version": "1.0.0",                                "license": [                                                                "OSL-3.0",                                              "AFL-3.0"                                ],                                "extra": {                                                                "map": [                                                                [                                                                "*",                                                                "Bss/Add                                Product                                Attribute"                                                                ]                                                                ]                                }                                }

And, add the following code in the app/code/Bss/AddProductAttribute/etc/module.xml

                      <?xml version="1.0"?>                                <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd"                                >                                <module name="Bss_AddProductAttribute" setup_version="1.0.0" />                                              </config>

Step 2: Create the file InstallData.php

<?php                      namespace Bss\AddProductAttribute\Setup;                                use Magento\Eav\Setup\EavSetup;                                use Magento\Eav\Setup\EavSetupFactory;                                use Magento\Framework\Setup\InstallDataInterface;                                use Magento\Framework\Setup\ModuleContextInterface;                                use Magento\Framework\Setup\ModuleDataSetupInterface;                                class InstallData implements InstallDataInterface                                {                                              private $eavSetupFactory;                                              public function __construct(EavSetupFactory $eavSetupFactory)                                              {                                              $this->eavSetupFactory = $eavSetupFactory;                                              }                                              public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)                                              {                                              $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);                                              $eavSetup->addAttribute(                                              \Magento\Catalog\Model\Product::ENTITY,                                              'custom_attribute',                                              [                                              'group' => 'General',                                              'attribute_set_id' => 'Bag',                                              'type' => 'varchar,                                              'backend' => '',                                              'frontend' => ''',                                              'label' => 'Custom Attribute',                                              'input' => 'text',                                              'class' => '',                                              'source' => ''',                                              'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,                                              'visible' => true,                                              'required' => false,                                              'user_defined' => true,                                              'default' => 0,                                              'searchable' => true,                                              'filterable' => true,                                              'comparable' => true,                                              'visible_on_front' => true,                                              'sort_order' => 101,                                              'option' => [                                              'values' => [],                                              ]                                ]                                              ]                                              );                                              }                                }

You must get to know the following setup on creating new attributes:

group : Name of groups that you want the created attribute to display in such as General, Bundle, Items, Images, Content, etc. Set Group to General to assign the attribute to all groups.
attribute_set_id : Define the attribute set to which the attribute is added, for example, Bag, Default, Gear, Bottom, etc.
type : Select the type of custom value saved in the database.
input : Specify the input type of the attributes such as select, text, boolean.
label : Set the label of the attribute displayed both in the frontend and in the backend.
source model : there provide a list of options.
frontend : Define how to display the attribute in the frontend.
backend : the admin can take some specific actions when loading or saving the attribute.
global : select scope of the attribute among global, website, or store.
require : decide whether the attribute is required or optional.
visible_on_store : decide whether the attribute is displayed in "More Information" tab of the frontend.
sort order : define the order of attribute.

Step 3: Run php bin/magento setup:upgrade

Please follow Admin panel ⇒ Stores ⇒ Product to find the custom attribute already added.

In case, you want to create product attributes with options programmatically, in step 2, please modify some codes, as below:

'source' => '' into :

'source' => Bss\AddProductAttribute\Model\Attribute\Source\CustomAttribute

Step 5: Add source model

In the app/code/Bss/AddProductAttribute/Model/Attribute/Source/CustomAttribute.php please add the code:

                      <?php                                namespace Bss\AddProductAttribute\Model\Attribute\Backend;                                class CustomAttribute extends \Magento\Eav\Model\Entity\Attribute\Source\AbstractSource                                {                                              /**                                              * Get all options                                              * @return array                                              */                                              public function getAllOptions()                                              {                                              if (!$this->_options) {                                              $this->_options = [                                              ['label' => __('One'), 'value' => 'one'],                                              ['label' => __('Two'), 'value' => 'two'],                                              ['label' => __('Three'), 'value' => 'three'],                                              ['label' => __('Four'), 'value' => 'four'],                                              ['label' => __('Five'), 'value' => 'five'],                                              ['label' => __('Six'), 'value' => 'six'],                                              ];                                              }                                              return $this->_options;                                              }                                /**                                * Get a text for option value                                *                                * @param string|integer $value                                * @return string|bool                                */                                public function getOptionText($value)                                {                                              foreach ($this->getAllOptions() as $option) {                                              if ($option['value'] == $value) {                                              return $option['label'];                                              }                                              }                                              return false;                                }                                }
