Puppet Server Provisioner

Type: puppet-server

The puppet-server Packer provisioner provisions Packer machines with Puppet by connecting to a Puppet master.

-> Note: Puppet will not be installed automatically by this provisioner. This provisioner expects that Puppet is already installed on the machine. It is common practice to use the shell provisioner before the Puppet provisioner to do this.

Basic Example

The example below is fully functional and expects a Puppet server to be accessible from your network.

{
   "type": "puppet-server",
   "extra_arguments": "--test --pluginsync",
   "facter": {
     "server_role": "webserver"
   }
}

Configuration Reference

The reference of available configuration options is listed below.

The provisioner takes various options. None are strictly required. They are listed below:

• client_cert_path (string) - Path to the directory on your disk that contains the client certificate for the node. This defaults to nothing, in which case a client cert won't be uploaded.

• client_private_key_path (string) - Path to the directory on your disk that contains the client private key for the node. This defaults to nothing, in which case a client private key won't be uploaded.

• execute_command (string) - The command-line to execute Puppet. This also has various configuration template variables available.

• extra_arguments (array of strings) - Additional options to pass to the Puppet command. This allows for customization of execute_command without having to completely replace or subsume its contents, making forward-compatible customizations much easier to maintain.

  This string is lazy-evaluated so one can incorporate logic driven by template variables as well as private elements of ExecuteTemplate (see source: provisioner/puppet-server/provisioner.go).

[
  {{if ne "{{user environment}}" ""}}--environment={{user environment}}{{end}}
]

• facter (object of key/value strings) - Additional facts to make available to the Puppet run.

• guest_os_type (string) - The remote host's OS type ('windows' or 'unix') to tailor command-line and path separators. (default: unix).

• ignore_exit_codes (boolean) - If true, Packer will ignore failures.

• prevent_sudo (boolean) - On Unix platforms Puppet is typically invoked with sudo. If true, it will be omitted. (default: false)

• puppet_bin_dir (string) - Path to the Puppet binary. Ideally the program should be on the system (unix: $PATH, windows: %PATH%), but some builders (eg. Docker) do not run profile-setup scripts and therefore PATH might be empty or minimal.

• puppet_node (string) - The name of the node. If this isn't set, the fully qualified domain name will be used.

• puppet_server (string) - Hostname of the Puppet server. By default "puppet" will be used.

• staging_dir (string) - Directory to where uploaded files will be placed (unix: "/tmp/packer-puppet-masterless", windows: "%SYSTEMROOT%/Temp/packer-puppet-masterless"). It doesn't need to pre-exist, but the parent must have permissions sufficient for the account Packer connects as to create directories and write files. Use a Shell provisioner to prepare the way if needed.

• working_directory (string) - Directory from which execute_command will be run. If using Hiera files with relative paths, this option can be helpful. (default: staging_directory)

  Execute Command

By default, Packer uses the following command (broken across multiple lines for readability) to execute Puppet:

cd {{.WorkingDir}} &&
	{{if ne .FacterVars ""}}{{.FacterVars}} {{end}}
	{{if .Sudo}}sudo -E {{end}}
	{{if ne .PuppetBinDir ""}}{{.PuppetBinDir}}/{{end}}
  puppet agent --onetime --no-daemonize --detailed-exitcodes
	{{if .Debug}}--debug {{end}}
	{{if ne .PuppetServer ""}}--server='{{.PuppetServer}}' {{end}}
	{{if ne .PuppetNode ""}}--certname='{{.PuppetNode}}' {{end}}
	{{if ne .ClientCertPath ""}}--certdir='{{.ClientCertPath}}' {{end}}
	{{if ne .ClientPrivateKeyPath ""}}--privatekeydir='{{.ClientPrivateKeyPath}}' {{end}}
	{{if ne .ExtraArguments ""}}{{.ExtraArguments}} {{end}}

The following command is used if guest OS type is windows:

cd {{.WorkingDir}} &&
	{{if ne .FacterVars ""}}{{.FacterVars}} && {{end}}
	{{if ne .PuppetBinDir ""}}{{.PuppetBinDir}}/{{end}}
  puppet agent --onetime --no-daemonize --detailed-exitcodes
	{{if .Debug}}--debug {{end}}
	{{if ne .PuppetServer ""}}--server='{{.PuppetServer}}' {{end}}
	{{if ne .PuppetNode ""}}--certname='{{.PuppetNode}}' {{end}}
	{{if ne .ClientCertPath ""}}--certdir='{{.ClientCertPath}}' {{end}}
	{{if ne .ClientPrivateKeyPath ""}}--privatekeydir='{{.ClientPrivateKeyPath}}' {{end}}
	{{if ne .ExtraArguments ""}}{{.ExtraArguments}} {{end}}

Default Facts

In addition to being able to specify custom Facter facts using the facter configuration, the provisioner automatically defines certain commonly useful facts:

• packer_build_name is set to the name of the build that Packer is running. This is most useful when Packer is making multiple builds and you want to distinguish them in your Hiera hierarchy.

• packer_builder_type is the type of the builder that was used to create the machine that Puppet is running on. This is useful if you want to run only certain parts of your Puppet code on systems built with certain builders.
