Puppet Class: role::eventbus

Defined in:
puppet/modules/role/manifests/eventbus.pp

Overview

Class role::eventbus

Sets up mediawiki EventBus extension and an EventGate instance. EventGate listens for POSTs of events on port 8192.

By default, eventgate will output events to the /vagrant/logs/eventgate-events.json log file, or to whatever the eventgate::output parameter is set (in hiera). If eventgate::output == 'kafka', Kafka will be installed and events will be produced to Kafka.
