Leroy's Designable Deployment Automation Workflows


Leroy is a new application deployment engine designed to allow developers, sysadmins, and devops engineers to design their own application deployment automation workflows to be used standalone, or part of any build automation system like Jenkins or Team City.

Free to use for commercial and non-commercial use under the creative commons license, Leroy is a "lean threaded" tool written for multiple platforms in C++.

Leroy allows the creation and templatization of application configuration. This is done in such a way where Leroy's internal properties are shared with the application's properties.

As Jason Korth, cocreator of Leroy at Epic Force explains, this application deployment engine consists of two major components: the agent and the controller.

"The agents are run on any system one wishes to perform tasks on. They do not listen on a port. Instead, they reach out to the controller and wait for it to come online. The controller contains all the configuration and artifacts needed to perform a deployment to all environments and is launched on demand,” he said.

Korth positions Leroy for Agile and for continuous integration and continuous deployment.

"Leroy provides a simplified programming language to describe the deployment of an application to all environments, end-to-end, in a common format. Leroy can also be used as an application development automation framework, as an extension in an existing build tool to provide automation deployment capabilities, and/or as a configuration management tool," he added.

Additional uses coming soon include Leroy being used as a library for an existing application that you want to have auto-update capability.
