if we want to center the row in a container, then we use the d-flex class for changing the data in row format, after using this class use the justify-content-center to center the row data or columns.

Syntax

<div class='d-flex justify-content-center'>

    // content            
</div>

Example 

<!doctype html>

<html lang='en'>
<head>
    <!-- Required meta tags -->
    <meta charset='utf-8'>
    <meta name='viewport' content='width=device-width, initial-scale=1, shrink-to-fit=no'>
    <!-- Bootstrap CSS -->
    <link rel='stylesheet' href='https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css' integrity='sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm' crossorigin='anonymous'>
    <title>Grid Demo</title>
</head>
<body>
    <div class='container alert-dark p-1'>
        <div class='row d-flex justify-content-center'>
            <div >
                <button class='border border-primary bg-primary text-center px-5 text-white '>1-1</button>
            </div>
            <div>
                <button class='border border-success bg-success text-center px-5 text-white '>1-2</button>
            </div>
        </div>
        <div class='row d-flex justify-content-center '>
            <div class='col-4'>
                <button class='border border-danger bg-danger text-center px-5 text-white '>1-1</button>
            </div>
            <div class='col-4'>
                <button class='border border-secondary bg-secondary text-center px-5 text-white '>1-2</button>
            </div>
        </div>
        <div class='row d-flex justify-content-center '>
            <div class='col-4'>
                <button class='border border-primary bg-primary text-center px-5 text-white '>1-1</button>
            </div>
            <div class='col-4'>
                <button class='border border-success bg-success text-center px-5 text-white '>1-2</button>
            </div>
            <div class='col-4'>
                <button class='border border-warning bg-warning text-center px-5 text-white '>1-2</button>
            </div>
