WordPress Readonly

A WordPress plugin that makes WordPress readonly. It's main use case is blue/green deployments, in which the active application slot requires a (short) readonly window to sync the database to the other slot.

Features:

• WP-CLI commands to enable and disable the readonly mode
• Notify logged-in users (in the admin) of upcoming readonly phase using notification.
• Disable login for all users during both prepare and readonly phase.
• Drop all POST requests during readonly phase with a 503 Service Unavailable.
• Refreshes admin pages for logged-in users once readonly mode is disabled.

Installation

This plugin is designed for WordPress websites that use Composer, such as Bedrock.

composer require pivvenit/wordpress-readonly

Enable readonly mode

./vendor/bin/wp readonly enable
