Operation Scenario

WordPress is a blogging platform developed with PHP. You can use it as a content management system, or use it to create websites on services that support PHP and MySQL databases.

This document describes how to use the tutum/wordpress Image to create a publicly accessible WordPress website.

Prerequisites

  • The tutm/wordpress Image includes all operating environments for WordPress, allowing you to pull and create the service directly.
  • Creating WordPress with single pod is for testing purposes only, and persistent data storage cannot be ensured. It is recommended that you use a self-built MySQL or TencentDB to store your data. For more information, please see WordPress Using TencentDB .

Steps
