Installation

The best way to install this extension is to start with the GSB Sitepackage Kickstarter extension.

Quick installation without GSB Sitepackage Kickstarter

In a composer-based TYPO3 installation you can install the extension EXT:gsb_clustered_caching via composer:

composer config -g gitlab-domains git.gsb-itzbund.de && \
composer config -g repositories.gsb-clustered-caching vcs https://gitlab.opencode.de/bmi/government-site-builder-11/extensions/gsb_clustered_caching
composer require itzbund/gsb-clustered-caching

In TYPO3 installations above version 11.5 the extension will be automatically installed. You do not have to activate it manually.

Configuration

You have to configure $GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['gsb_clustered_caching']['serviceBroadcaster'] to a proper value, e.g.

http://service-broadcaster:8080/broadcast/gsb11-frontend-headless/8080/gsb-clustered-caching/,http://service-broadcaster:8080/broadcast/gsb11-backend-headless/8080/gsb-clustered-caching/

This is a combination of this extension listening to the the /gsb-clustered-caching/ endpoint and the service-broadcaster configuration.

Usage

This extension works without manual action. This is described here.

Command

This extension provides a command that will trigger a cache flush if a system state change has been identified. A state change can be identified by

  • providing a version argument
  • the composer state
typo3 gsbclusteredcaching:flushCacheOnStateChange [version] [-g groups]

There is one argument (the version) and an optional option (--groups or -g) that defines which cache groups should be flushed.
