Strapi Plugin Redcron

Overview

The Strapi Redcron plugin is a drop-in replacement for the Strapi cron plugin that uses Redlock to prevent multiple instances of Strapi from running the same cron job at the same time. This helps to avoid race conditions and potential issues with the database or other integrated services when horizontally scaling Strapi.

Features

• Drop-in replacement for the Strapi cron plugin
• Uses Redlock to prevent multiple instances of Strapi from running the same cron job simultaneously
• Requires minimal configuration

Usage

To use the Strapi Redcron plugin, you can add the bypassRedcron property to your cron job configuration. This will bypass the redlock logic and allow multiple instances of Strapi to run the same cron job simultaneously.

Note: You need to use the object format of the cron config and provide a unique name for the key property, as Redis needs to lock onto a key that is the same across all instances of Strapi.

Example

Here is an example of how to use the Strapi Redcron plugin:

{
  "name": "myCronJob",
  "schedule": "*/30 * * * *",
  "bypassRedcron": true,
  ...
}

To run multiple Strapi instances, add server.js to the root of your wrapper project and run pm2 start --name="mystrapiapp" server.js -i 2.
