To share your module with other Puppet users, get contributions to your modules, and maintain your module releases, publish your module on the Puppet Forge. The Forge is a community repository of modules, written and contributed by open source Puppet and Puppet Enterprise users.
To publish your module:
- Create a Puppet Forge account, if you don’t already have one.
- Prepare your module for packaging.
- Add module metadata in the
metadata.jsonfile. - Build an uploadable tarball of your module.
- Upload your module using the Puppet Forge’s web interface.

Naming your module
Your module has two names: a short name, like “mysql” and a long name that includes your Forge username, like “puppetlabs-mysql”.
The Puppet Forge requires the module long name. This name is composed of your Forge username and the short name of your module. For example, the user named “puppetlabs” maintains a “mysql” module, which is known to the Forge as “puppetlabs-mysql”. Be sure to use this long name in your module’s metadata.json file. This helps disambiguate modules that might have common short names, such as “mysql” or “apache.”
However, your module directory on disk must use the short name, without the username prefix. (Module directory names cannot contain dashes or periods; only letters, numbers, and underscores). As long as you have the correct long name in your metadata.json file, the puppet module build command will use the correct names in the correct places.
Note: Although the Puppet Forge expects to receive modules named
username-module, its web interface presents them asusername/module. Always use theusername-modulestyle in your metadata files and when issuing commands.

Create a Puppet Forge account
To publish your modules to the Puppet Forge, you need to create a Puppet Forge account.
-
In your web browser, navigate to the Forge website and click Sign Up.
-
Fill in your details. The username you pick will be the first part of your module long name (such as “bobcat/apache”).
-
After you sign up, you will receive a verification email. After you verify your email, you can publish modules to the Forge.
Preparing your module
Before you build your module package for publishing, you’ll need to make sure it’s properly prepared.
To do this, you’ll exclude unnecessary files from your package or repository, remove or ignore any symlinks your module contains, and make sure your metadata.json contains the correct metadata.
Note: In order to successfully publish your module to the Puppet Forge and ensure that everything is rendered correctly, your README, license file, changelog, and metadata.json must be UTF-8 encoded. If you used
puppet module generateto create your module, these files are UTF-8 encoded already.
Excluding files from the package
To exclude certain files from your module build, include them in either a .gitignore or a .pmtignore file. This is useful for excluding files that are not needed to run the module, such as files generated by spec tests. The ignore file must be in the root directory.
.pmtignore example
import/
/spec/fixtures/
.tmp
*.lock
*.local
.rbenv-gemsets
.ruby-version
build/
docs/
tests/
log/
junit/
tmp/
The .pmtignore file excludes files during puppet module build only. For example, you might want spec tests in your source control but not in your module package, so you would list them in .pmtignore. To prevent files, such as those in temporary directories, from ever being checked into Git, use .gitignore.
If you have both a .pmtignore and a .gitignore file, the puppet module command uses the .pmtignore file.
Removing symlinks from your module
Symlinks in modules are unsupported. If your module contains symlinks, either remove them or ignore them before you build your module.
If you try to build a module that contains symlinks, you will receive the following error:
Warning: Symlinks in modules are unsupported. Please investigate symlink manifests/foo.pp->manifests/init.pp.
Error: Found symlinks. Symlinks in modules are not allowed, please remove them.
Error: Try 'puppet help module build' for usage
Adding module metadata in metadata.json
To publish your module on the Forge, it must contain required metadata in a metadata.json file.
If you generated your module using the puppet module generate command, you’ll already have a metadata.json file. Check it and make any necessary edits.
If you assembled your module manually, you must make sure that you have a metadata.json file in your module’s main directory. For details on writing or editing the metadata.json file, see the related topic about module metadata.
Modulefiles
If you maintain older modules, you might find the metadata stored in a Modulefile. Move any metadata contained in the Modulefile to the metadata.json. Modulefiles were deprecated in Puppet 3 and removed in Puppet 4. They are now treated like any other text file in the root directory of the module.

Build your module
To upload your module to the Puppet Forge, you first must build the module package.
-
From the command line, run
puppet module build <MODULE DIRECTORY>. This command generates a.tar.gzpackage and saves it in the module’spkg/subdirectory.For example:
# puppet module build /etc/puppetlabs/puppet/modules/mymodule Building /etc/puppetlabs/puppet/modules/mymodule for release /etc/puppetlabs/puppet/modules/mymodule/pkg/examplecorp-mymodule-0.0.1.tar.gz
Upload a module to the Forge
To publish a new module release to the Puppet Forge, upload the module tarball to the Forge using the web interface.
Your module package should be a compiled tar.gz package of 10MB or less.
-
In your web browser, navigate to the Puppet Forge and log in.
-
Click Publish in the upper right hand corner of the screen.
-
On the upload page, click Choose File and use the file browser to locate and select the release tarball. Then click Upload Release.
After a successful upload, your browser should load the new release page of your module, with any errors popping up on the same screen. Your module’s README, Changelog,and License files are displayed on your module’s Forge page.
Delete a module release from the Forge
If you want to delete a release of your module, you can do so from the Puppet Forge’s web interface.
A deleted release is still downloadable via the Forge page or puppet module command if a user requests the module by specific version. You cannot delete a released version and upload a new version of the same release.
-
In your web browser, navigate to the Puppet Forge and log in.
-
Click Your Modules.
-
Go to the module page of the module release you want to delete.
-
Locate Select another release, choose the release you want from the drop-down list, and click Delete.
-
A confirmation page will load, and you must supply a reason for the deletion. Note: Your reason will be visible to Forge users.
-
Click Yes, delete it.
-
On your module page, you will see a banner confirmation of the deletion.

Finding and downloading deleted modules
You can still search for and download a specific release of a module on the Puppet Forge, even if the release has been deleted.
Normally, deleted modules do not appear in Forge search results. To include deleted modules in your search, check Include deleted modules in the Forge search filter panel.
To download a deleted release of a specific module, select the release from the Select another release drop-down list on the module page. The release is marked as deleted but is still an option in the menu.
If you select the deleted release, a warning banner appears on the page with the reason for deletion. To download the deleted release anyway, click Download or install it with the puppet module install command.
