README

A Magento 2 module that automatically keeps your Varnish configuration up to date by downloading a remote VCL template, processing it with Magento's native placeholder substitution, and applying it to the running Varnish instance.

How it works

1. A cron job runs once a day
2. The VCL template is downloaded from a configured URL
3. Magento's built-in VclGenerator replaces all standard placeholders with live values from the store configuration (backend host/port, access list, grace period, SSL offload header, design exceptions)
4. The processed VCL is saved to var/tmp/varnish_extended.vcl
5. The new configuration is loaded and activated via varnishadm:

   varnishadm vcl.load magento2 <file>
   varnishadm vcl.use magento2
   

NOTE: vcl.load and vcl.use commands are not flushing the already cached pages.

Requirements

• Magento 2 with Magento_PageCache module
• PHP 8.1+
• varnishadm available in the system PATH of the user running Magento cron

Installation

composer require taurus-media/module-varnish-config
bin/magento module:enable Taurus_VarnishConfig
bin/magento setup:upgrade

CLI command

The VCL update can also be triggered manually:

bin/magento taurus:varnish:update-vcl

This runs the same logic as the cron job and exits with code 0 on success or 1 on failure, making it suitable for use in deployment pipelines.
