Overview

A module for upgrading Puppet agents. Supports upgrading from Puppet 3 packages and puppet-agent packages, to puppet-agent packages (i.e. Puppet 4).

Module Description

The puppet_agent module installs the Puppet Collection 1 repo (as a default, and on systems that support repositories); migrates configuration required by Puppet to new locations used by puppet-agent; and installs the puppet-agent package, removing the previous Puppet installation. When starting from Puppet 3, it will upgrade to the latest Puppet open-source release, or to the latest puppet-agent package supported by your PE installation.

If a package_version parameter is provided, it will ensure that puppet-agent version is installed. The package_version parameter is required to perform upgrades starting from a puppet-agent (Puppet 4) package.

This module expects Puppet to be installed from packages.

Note: this is the last release that will support Puppet 3 and Ruby <2.1.

Setup

What puppet_agent affects

  • Puppet, Facter, Hiera, and MCollective.
  • Puppet's SSL directory and puppet.conf.
  • MCollective's server.cfg and client.cfg.
  • Removes deprecated settings from puppet.conf.
  • Updates puppet.conf and server.cfg for behavioral changes in puppet-agent (future parser is now the default, and MCollective has a new varlog location).

Setup Requirements

Your agents must be running Puppet 3 with stringify_facts set to 'false', or Puppet 4+. Agents should already be pointed at a master running Puppet Server 2.1 or greater, and thus successfully applying catalogs compiled with the Puppet 4 language.

Puppet 3.7 with future parser is required to compile this module, meaning it may be applied to masterless Puppet 3.7+, or earlier Puppet 3 agents connecting to a Puppet 3.7+ master.

Beginning with puppet_agent

Install the puppet_agent module with puppet module install puppetlabs-puppet_agent.

Usage

Puppet 3 Upgrades

Add the class to agents you want to upgrade:

include ::puppet_agent

This installs the latest released version of Puppet from Puppet Collection 1.

To upgrade with this module, first stand up a Puppet Server 2.1 master---which supports backward compatibility with Puppet 3 agents---and point the agent you want to upgrade at that master. Once you've confirmed the agent runs successfully against the new master, and thus the Puppet 4 language, apply the class to the agent and confirm that it checks back in after a successful upgrade. Further details on upgrading are available here.

As part of preparing the agent for Puppet 4, the module performs several significant steps:

  • Copies SSL files (based on their location settings: ssldir, certdir, privatedir, privatekeydir, publickeydir, requestdir) to new Puppet 4 defaults, and restore those settings to default in puppet.conf.
  • Resets non-deprecated settings to defaults: disable_warnings, vardir, rundir, libdir, confdir, ssldir, and classfile.
  • Resets logfile in MCollective's server.cfg and client.cfg.
  • Adds new libdir and plugin.yaml locations to MCollective's server.cfg and client.cfg.

Note: The upgrade does not change several config options. Anything else that's been explicitly configured will not be changed to reflect new default locations in Puppet 4. Some of these options are:

  • Puppet's logdir
  • MCollective's logfile

Puppet 4 Upgrades

Add the class to agents you want to upgrade, specifying the desired puppet-agent version:

class {'::puppet_agent':
  package_version => '1.4.0',
}

This will ensure the version 1.4.0 of the puppet-agent package is installed. For version 1.4.0 and later, it will also remove the deprecated pluginsync setting from puppet.conf, unless explicitly managed elsewhere.

Reference

Public classes

Private classes

  • puppet_agent::install: Installs packages.
  • puppet_agent::install::remove_packages: For platforms that can't perform in-place upgrades, removes the old packages.
  • puppet_agent::install::remove_packages_osx: Removes the old packages on Mac OS X.
  • puppet_agent::osfamily::*: Platform-specific preparation performed before upgrades.
  • puppet_agent::prepare: Prepares the agent for upgrade.
  • puppet_agent::prepare::package: Stages packages locally for install, on platforms that can't install from remote packages.
  • puppet_agent::prepare::*: Prepare various file and ssl configuration.
  • puppet_agent::service: Ensures the services are running.
  • puppet_agent::windows::install: Handles Windows package installation.

Parameters

Class: puppet_agent

arch

The architecture version you wish to install. Defaults to $::architecture. This parameter is ignored in Windows Server 2003.

collection

The Puppet Collection to track. Defaults to PC1.

is_pe

Install from Puppet Enterprise repos. Enabled if communicating with a PE master.

manage_repo

Boolean to determine whether to configure zypper/yum/apt/solaris repositories. Defaults to true. If set to false, it is assumed an internally hosted repository will be used for the installation, and the native package providers will be used to query pre-configured repos on the host being upgraded.

package_name

The package to upgrade to, i.e., puppet-agent. Currently, the default and only accepted value is puppet-agent.

package_version

The package version to upgrade to. When upgrading from Puppet < 4.0, defaults to the puppet master's latest supported version if compiled with A PE master or undef otherwise (meaning get the latest Open Source release). Explicitly specify a version to upgrade from puppet-agent packages (implying Puppet >= 4.0).

service_names

An array of services to start, normally puppet and mcollective. If the array is empty, no services are started.

source

Alternate source from which you wish to download the latest version of Puppet. On the Windows operating system this is the absolute path to the MSI file to install, for example:

  source => 'C:/packages/puppet-agent-1.7.0-x64.msi'
install_dir

The directory the puppet agent should be installed to. This is only applicable for Windows operating systems and when upgrading the agent to a new version; it will not cause re-installation of the same version to a new location. This must use backslashes for the path separator, and be an absolute path, for example:

  install_dir => 'D:\Program Files\Puppet Labs'
install_options

An array of additional options to pass when installing puppet-agent. Each option in the array can either be a string or a hash. Each option will automatically be quoted when passed to the install command. With Windows packages, note that file paths in an install option must use backslashes. (Since install options are passed directly to the installation command, forward slashes won't be automatically converted like they are in file resources.) Note also that backslashes in double-quoted strings must be escaped and backslashes in single-quoted strings can be escaped.

  install_options => ['PUPPET_AGENT_ACCOUNT_DOMAIN=ExampleCorp','PUPPET_AGENT_ACCOUNT_USER=bob','PUPPET_AGENT_ACCOUNT_PASSWORD=password']
msi_move_locked_files

This is only applicable for Windows operating systems. There may be instances where file locks cause unncessary service restarts. By setting to true, the module will move files prior to installation that are known to cause file locks. By default this is set to false.

  msi_move_locked_files => true

Limitations

Mac OS X Open Source packages are currently not supported.

Known issues

  • In masterless environments, modules installed manually on individual agents cannot be found after upgrading to Puppet 4.x. You should reinstall these modules on the agents with puppet module install.

In addition, there are several known issues with Windows:

  • To upgrade the agent by executing puppet agent -t interactively in a console, you must close the console and wait for the upgrade to finish before attempting to use the puppet command again.
  • MSI installation failures do not produce any error. If the install fails, puppet_agent continues to be applied to the agent. If this happens, you'll need to examine the MSI log file to determine the failure's cause. You can find the location of the log file in the debug output from either a puppet apply or an agent run; the log file name follows the pattern puppet-<timestamp>-installer.log.
  • On Windows Server 2003, only x86 is supported, and the arch parameter is ignored. If you try to force an upgrade to x64, Puppet installs the x86 version with no error message.
  • On Windows Server 2003 with Puppet Enterprise, the default download location is unreachable. You can work around this issue by specifying an alternate download URL in the source parameter.

Specifically in the 1.2.0 Release:

  • For Windows, you must trigger an agent run after upgrading so that Puppet can create the necessary directory structures.

Development

Puppet, Inc. modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad hardware, software, and deployment configurations that Puppet is intended to serve. We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things. For more information, see our module contribution guide.
