Puppet Module Tool
The Puppet Module Tool,
puppet-module, creates, installs and searches for
modules on the Puppet Forge at http://forge.puppetlabs.com
puppet-module, you must have the following installed:
- Ruby 1.8.x: http://www.ruby-lang.org/en/downloads/
- RubyGems 1.3.x: http://rubygems.org/pages/download/
- Puppet 0.25.x: http://www.puppetlabs.com/
The source code for this tool is available online at http://github.com/puppetlabs/puppet-module-tool
You can checkout the source code by installing the
git distributed version
control system and running:
git clone git://github.com/puppetlabs/puppet-module-tool.git
There are a number of ways to run the
From an official gem: Install it by running:
sudo gem install puppet-module
From a locally-built gem: Checkout the source code and from the checkout directory, run:
# Build the gem rake gem # Install the file produced by the above command, e.g.: sudo gem install pkg/puppet-module-0.3.0.gem
From a source code checkout: Checkout the source code and from the checkout directory, run:
Display the program's built-in help by running:
Display information on a specific command by running a command like:
puppet-module help install
Many commands will use a specific repository if you pass it to the
option at the end, like:
puppet-module search mymodule -r http://forge.puppetlabs.com/
Search for modules
Searching displays modules on the repository that match your query.
For example, search the default repository for modules whose names
include the substring
puppet-module search mymodule
Install a module release
Installing a module release from a repository downloads a special archive file. This archive is then automatically unpacked into a new directory under your current directory. You can then add this module directory to your Puppet configuration files to use it.
For example, install the latest release of the module named
myuser from the default repository:
puppet-module install myuser-mymodule
Or install a specific version:
puppet-module install myuser-mymodule --version=0.0.1
Generate a module
Generating a new module produces a new directory prepopulated with a directory structure and files recommended for Puppet best practices.
For example, generate a new module:
puppet-module generate myuser-mymodule
The above command will create a new module directory called
myuser-mymodule under your current directory with the generated files.
Please read the files in this generated directory for further details.
Build a module release
Building a module release processes the files in your module directory and produces a special archive file that you can share or install.
For example, build a module release from within the module directory:
The above command will report where it created the module release archive file.
For example, if this was version
myuser-mymodule, then this
would have created a
pkg/myuser-mymodule-0.0.1.tar.gz release file.
The build process reads a
Modulefile in your module directory and uses
its contents to direct its work.
Modulefile is a Ruby domain-specific language (DSL).
Here's an example of a
name 'myuser-mymodule' version '0.0.1' dependency 'otheruser-othermodule', '1.2.3'
The build process reads the
Modulefile and uses it to build a
metadata.json file. This generated JSON file is included in the module
release archive so that repositories and installers can extract details
from your release. Do not edit this
metadata.json file yourself
because it's clobbered each time during the build process -- you should
make all your changes to the
All the files in the
pkg directory of your module directory are
artifacts of the build process. You can delete them when you're done.
Share a module
Sharing a module release with others helps others avoid reinventing the wheel, and encourages them to help with your work by improving it. For every module you share, we hope you'll find many modules by others that will be useful to you.
You can share your modules at http://forge.puppetlabs.com/
Building and sharing a new module version
To build and share a new module version:
- Edit the
Modulefileand increase the
- Run the
puppet-module buildas explained in the Build a module release section.
- Upload the new release file as explained in the Share a module section.
Cleaning the cache
Modules that you install are saved to a cache within your
directory. This cache can be cleaned out by running:
Deleting a module
The tool does not keep track of what modules you have installed. TO delete a module just delete the directory the module was extracted into.
This is new and exciting for us. We have many plans for this and what you see now is just the beginning. If you have ideas, please get in touch. Puppet Labs can be contacted at: firstname.lastname@example.org
