Welcome to the Puppet 4.0 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 4.0, Ruby, Facter, Hiera, and supporting code; and a puppetserver package that installs Puppet Server 2.0.

To install Puppet 4.0, 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. We’ll make an update to the AIO package available in the coming month to address this issue.

  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.
