A Puppetfile specifies detailed information about each environment's Puppet code and data, including where to get that code and data from, where to install it, and whether to update it.
Both Code Manager and r10k use a Puppetfile to install and manage the content of your environments.
The Puppetfile specifies the modules and data that you want in each environment. The Puppetfile can specify what version of modules you want, how the modules and data are to be loaded, and where they are placed in the environment.
A Puppetfile is a formatted text file that specifies the modules and data that you want brought into your control repo. Typically, a Puppetfile controls content such as:
- Modules from the Forge
- Modules from Git repositories
- Data from Git repositories
For each environment that you want to manage content in, you need a
Puppetfile. You'll create a base

base Puppetfile. You can then edit
each environment's Puppetfile as
Managing modules with a Puppetfile
With code management, install and manage your modules only with a Puppetfile.
Almost all Puppet
manifests are kept in modules, collections of Puppet code and data with a specific directory structure. By
default, Code Manager and r10k install content in a modules directory
./modules) in the same directory the
Puppetfile is in. For example,
puppetlabs-apache module in
the Puppetfile normally installs the
./modules/apache. To learn
more about modules, see the module documentation.
Code Manager and r10k, do
not use the
command to install or manage modules. Instead, code management depends on the Puppetfile in each of your
environments to install, update, and manage your modules. If you've installed modules
to the live code directory with
install, Code Manager deletes them.
The Puppetfile does NOT include Forge module dependency resolution. You must make sure that you have every module needed for all of your specified modules to run. In addition, Forge module symlinks are unsupported; when you install modules with r10k or Code Manager, symlinks are not installed.
Including your own modules
If you develop your own
modules, maintain them in version control and include them in your Puppetfile as you would declare any module from a
repository. If you have content in your control repo's module directory that is not listed in your Puppetfile, code management purges it. (The control repo
module directory is, by default,
./modules relative to the location of the Puppetfile.)
Creating a Puppetfile
Your Puppetfile manages the content you want to maintain in that environment.
In a Puppetfile, you can declare:
- Modules from the Forge.
- Modules from a Git repository.
- Data or other non-module content (such as Hiera data) from a Git repository.
You can declare any or all of this content as needed for each environment. Each module or repository is specified with a `mod` directive, along with the name of the content and other information the Puppetfile needs so that it can correctly install and update your modules and data.
It's best to create your first Puppetfile in your production branch. Then, as you create branches based on your production branch, edit each branch's Puppetfile as needed.

You can declare modules from the Forge or you can declare Git repositories in your Puppetfile. See the related topics about declaring content in the Puppetfile for details and code examples.
After creating your Puppetfile, configure Code Manager or r10k.
Change the Puppetfile module installation directory
If needed, you can change the directory to which the Puppetfile installs all modules.
To specify a module installation path other than the default modules
./modules), use the

repositories and set the

moduledir directive. See the related topic about how to declare content as

Declare Forge modules in the Puppetfile

Specify modules by their full name. You can specify the most recent version of a module, with or without updates, or you can specify a specific version of a module.

moddirective. For each module, pass the module name as a string, and optionally, specify what version of the module you want to track.
If you specify no
options, code management installs the latest version and keeps the module at
that version. To keep the module updated, specify
:latest. To install a specific version of the
module and keep it at that version, specify the version number as a
mod 'puppetlabs/apache' mod 'puppetlabs/ntp', :latest mod 'puppetlabs/stdlib', '0.10.0'
Installs the latest version of the apache module, but does not update it.
Installs the latest version of the ntp module, and updates it when environments are deployed.
Installs version 0.10.0 of the stdlib module, and does not update it.
Declare Git repositories in the Puppetfile
List the modules, data, or other non-module content that you want to install from a Git repository.
To specify any
environment content as a Git
repository, use the

:git option. This is
useful for modules you don't get from the Forge, such as your own modules, as well as data or
other non-module content.

specific installation paths for individual modules. When you set this option for a specific
repository, it overrides the

This example installs site data content from the

To declare content protected by SSH private keys, declare the content as a repository, and then configure the private key setting in your code management tool.
Declare your repository content, specifying the Git repo by the SSH URL.
mod 'myco/privatemod', :git => '[email protected]:myco/privatemod.git'
Configure the correct private key by setting Code Manager or r10k parameters in Hiera:
- To set a key for all Git operations, use the private key setting under

private key in the
git-settingsfor each specific remote.
- To set a key for all Git operations, use the private key setting under
Keep repository content at a specific version
The Puppetfile can maintain repository content at a specific version.
To specify a particular repository version, declare the version you want to track with the following options. Setting these options maintains the repository at that version and deploys any updates made to that particular version.
ref: Specifies the Git reference to check out. This option can reference either a tag, a commit, or a branch.
tag: Specifies the repo by a certain tag value.
commit: Specifies the repo by a certain commit.
branch: Specifies a certain branch of the repo.
default_branch: Specifies a default branch to use for deployment if the specified
branchcannot be deployed. You must also specify one of the other version options. This is useful if you are tracking a relative branch of the control repo.
puppetlabs/apache and specify the '0.9.0' tag, use the
mod 'apache', :git => 'https://github.com/puppetlabs/puppetlabs-apache', :tag => '0.9.0'
puppetlabs/apache and use the
branch option to track the ‘proxy_match’ branch.
mod 'apache', :git => 'https://github.com/puppetlabs/puppetlabs-apache', :branch => 'proxy_match'
puppetlabs/apache and use the
commit option to track the '8df51aa' commit.

deployed. This means that as you create new branches, you don't have to edit the inherited
