Monolithic Master Edit

Version v0.0.1
Published on Jul 9, 2019

A simple master/agent architecture with all services running on one master.

Intended Audience

This architecture is intended for small to medium static infrastructures and is easier than multiple compile masters to set up and maintain. Generally speaking, redundancy and HA are most useful for dynamic environments. A stopped Puppet master doesn’t prevent the existing configuration from being enforced but it will halt any new deployments or configuration updates. If those constraints fit your needs, then this architecture is suggested.

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

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.

Code Deployment

r10k is considered the default Puppet code deployment tool. Install it on your master 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.

Puppet Stack

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