Magento 2- How to create user role programmatically by custom module installer

Here we create admin user role programmatically by custom module installer with specific resources.

1=>First you need to create an installer file named InstallData.php in our custom module Setup folder

complete path: app/code/ModuleNameSpace/YourModuleName/Setup

<?php

namespace ModuleNameSpace\YourModuleName\Setup;

use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

/* For get RoleType and UserType for create Role   */;
use Magento\Authorization\Model\Acl\Role\Group as RoleGroup;
use Magento\Authorization\Model\UserContextInterface;

/**
 * @codeCoverageIgnore
 */
class InstallData implements InstallDataInterface
{
    /**
     * RoleFactory
     *
     * @var roleFactory
     */
    private $roleFactory;

     /**
     * RulesFactory
     *
     * @var rulesFactory
     */
    private $rulesFactory;
    /**
     * Init
     *
     * @param \Magento\Authorization\Model\RoleFactory $roleFactory
     * @param \Magento\Authorization\Model\RulesFactory $rulesFactory
     */
    public function __construct(
        \Magento\Authorization\Model\RoleFactory $roleFactory, /* Instance of Role*/
        \Magento\Authorization\Model\RulesFactory $rulesFactory /* Instance of Rule */ 
        /*this define that which resource permitted to wich role */
        )
    {
        $this->roleFactory = $roleFactory;
        $this->rulesFactory = $rulesFactory;
    }

    /**
     * {@inheritdoc}
     * @SuppressWarnings(PHPMD.ExcessiveMethodLength)
     */
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        /**
        * Create Warehouse role 
        */
        $role=$this->roleFactory->create();
        $role->setName('YourRoleName') //Set Role Name Which you want to create 
                ->setPid(0) //set parent role id of your role
                ->setRoleType(RoleGroup::ROLE_TYPE) 
                ->setUserType(UserContextInterface::USER_TYPE_ADMIN);
        $role->save();
        /* Now we set that which resources we allow to this role */
        $resource=['Magento_Backend::admin',
					'Magento_Sales::sales',
					'Magento_Sales::create',
					'Magento_Sales::actions_view', //you will use resource id which you want to allow
					'Magento_Sales::cancel'
				  ];
        /* Array of resource ids which we want to allow this role*/
        $this->rulesFactory->create()->setRoleId($role->getId())->setResources($resource)->saveRel();
    }
}

You can get resources id as explain in following snap
