Puppet (Masterless) Provisioner

Type: puppet-masterless

The masterless Puppet provisioner configures Puppet to run on the machines by Packer from local modules and manifest files. Modules and manifests can be uploaded from your local machine to the remote machine or can simply use remote paths (perhaps obtained using something like the shell provisioner). Puppet is run in masterless mode, meaning it never communicates to a Puppet master.

Note that 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 the configured manifest file to exist relative to your working directory:

{
  "type": "puppet-masterless",
  "manifest_file": "site.pp"
}

Configuration Reference

The reference of available configuration options is listed below.

Required parameters:

• manifest_file (string) - The manifest file for Puppet to use in order to compile and run a catalog. This file must exist on your local system and will be uploaded to the remote machine.

Optional parameters:

• execute_command (string) - The command used to execute Puppet. This has various configuration template variables available. See below for more information.

• facter (object, string keys and values) - Additonal facts to make available when Puppet is running.

• hiera_config_path (string) - The path to a local file with hiera configuration to be uploaded to the remote machine. Hiera data directories must be uploaded using the file provisioner separately.

• manifest_dir (string) - The path to a local directory with manifests to be uploaded to the remote machine. This is useful if your main manifest file uses imports. This directory doesn't necessarily contain the manifest_file. It is a separate directory that will be set as the "manifestdir" setting on Puppet.

• module_paths (array of strings) - This is an array of paths to module directories on your local filesystem. These will be uploaded to the remote machine. By default, this is empty.

• prevent_sudo (boolean) - By default, the configured commands that are executed to run Puppet are executed with sudo. If this is true, then the sudo will be omitted.

• staging_directory (string) - This is the directory where all the configuration of Puppet by Packer will be placed. By default this is "/tmp/packer-puppet-masterless". This directory doesn't need to exist but must have proper permissions so that the SSH user that Packer uses is able to create directories and write into this folder. If the permissions are not correct, use a shell provisioner prior to this to configure it properly.

Execute Command

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

{{.FacterVars}}{{if .Sudo}} sudo -E {{end}}puppet apply \
  --verbose \
  --modulepath='{{.ModulePath}}' \
  {{if ne .HieraConfigPath ""}}--hiera_config='{{.HieraConfigPath}}' {{end}} \
  {{if ne .ManifestDir ""}}--manifestdir='{{.ManifestDir}}' {{end}} \
  --detailed-exitcodes \
  {{.ManifestFile}}

This command can be customized using the execute_command configuration. As you can see from the default value above, the value of this configuration can contain various template variables, defined below:

• FacterVars - Shell-friendly string of environmental variables used to set custom facts configured for this provisioner.
• HieraConfigPath - The path to a hiera configuration file.
• ManifestFile - The path on the remote machine to the manifest file for Puppet to use.
• ModulePath - The paths to the module directories.
• Sudo - A boolean of whether to sudo the command or not, depending on the value of the prevent_sudo configuration.
