Roadrunner Temporal

The repository contains a number of plugins which enable workflow and activity processing for PHP processes. The communication protocol, supervisor, load-balancer is based on RoadRunner PHP Application Server.

Installation

Temporal is official plugin of RoadRunner and available out of the box in RoadRunner 2.0.

Read more about application server installation here.

To install PHP-SDK:

Read how to configure your worker and init workflows here.

Testing

To test integration make sure to install Golang and PHP 7.4+ at the same host. Composer is required to manage the extension.

$ make install-dependencies
$ make start-docker-compose
$ make test
