Load Balanced Edit

Version v0.0.2
Published on Aug 6, 2023

A complete server/agent architecture with multiple compilers and load balancing for redundancy.

Intended Audience

This architecture is intended for large infrastructures or dynamic infrastructures that require the redundancy of multiple compilers.

Setup and Usage

{write a guide on how to deploy, configure, and use this architecture}

Git Repository

We recommend organizing your code as a Control Repository with branches for environments. See the reference repository for an example.


Foreman is a complete lifecycle management tool for physical and virtual servers. It will provide you with a graphical classifier, a Hiera data source, and report monitoring. It also includes the power to easily automate repetitive tasks, quickly deploy applications, and proactively manage servers, on-premise or in the cloud.

Puppet Webhook

Configure Puppet Webhook to receive webhook events from your code repository and automate your code deploys. This service should be installed on the main Puppet Server. You might consider using the Bolt task from the puppet-r10k module to trigger code deployments on each compiler, or you can also install Puppet Webhook on each.

Code Deployment

r10k is considered the default Puppet code deployment tool. Install it on the main Puppet Server and each compiler in your infrastructure and use it to deploy your control repository as needed.

If you’re a Golang shop, you might consider g10k as well.

Load Balancer

Puppet Agent Server connections are connections with long duration. Therfore it is highly recommended to use least_connection algorithm.

Any kind of load-balancer is sufficient. HAProxy is well supported and allows flexibility.

Puppet Stack

We recommend managing each of these components with the supported module.
