Puppet 4.1 Reference Manual

This version of Puppet is not included in Puppet Enterprise. The latest version of PE includes Puppet 4.4. A newer version is available; see the version menu above for details.

Welcome to the Puppet 4.1 Reference Manual. Use the navigation to the left to get around.

What Is This?

For an introduction to how Puppet manages systems, see the Overview of Puppet’s Architecture.

Getting Started

Puppet 4 consists of:

  • A puppet-agent “All-in-One” package that installs Puppet, Ruby, Facter, Hiera, and supporting code.
  • A puppetserver package that installs Puppet Server.

To install these, read the pre-install instructions, then see the Puppet installation guides for Linux and Windows.

Upgrading from Puppet 3.x

In order to get this release into the world as quickly as possible we had to make two significant tradeoffs for in-place upgrades:

  1. Due to the changes in filesystem paths for configuration and SSL files, you’ll need to take a few extra steps to install Puppet Agent / Puppet 4 on an existing Puppet 3.x host and have it “just work.” Check out the Agent Upgrade doc for details.

  2. Changes to Puppet’s agent-to-master network communication mean that 4.x agents can only talk to 4.x masters, so the process for upgrading within a major series (“Upgrade your masters first, then agents”) isn’t sufficient. We’re working to make 3.x agents able to talk to the next release of Puppet Server. We do have step by step instructions to help you set up 4.x masters.

Getting Around

This manual is split into several sections, which can be reached from the left sidebar. A few notable pages:

  • The Release Notes have information about what’s new and different in Puppet 4.1, and track changes from patch releases.
  • If you’re an experienced Puppet user, you’ll want to take a look at the Where Did Everything Go? page.
  • The Resource Type Reference is the page where experienced Puppet users spend most of their time.
  • Puppet uses its own configuration language, which is documented in the language section of this reference. Two good starting points are:
    • The Language Summary, which gives an overview and some context.
    • The Visual Index, which can help you find docs for syntax when you know what it looks like but don’t know what it’s called.
  • Modules explains how to organize your Puppet manifests, obtain pre-existing modules, and publish your own modules for public use.
