Installing modules

Install, upgrade, and uninstall Forge modules from the command line with the puppet module command.

The puppet module command provides an interface for managing modules from the Puppet Forge. Its interface is similar to other common package managers, such as gem, apt-get, or yum. You can install, upgrade, uninstall, list, and search for modules with this command.

Important: If you are using a code-management tool such as r10k, do not use the puppet module command. With code management, you install modules with a Puppetfile; code management purges any modules that were installed with the puppet module command.

Solaris Note: To use puppet module commands on Solaris systems, you must first install gtar.

Using puppet module behind a proxy

To use the puppet module command behind a proxy, set the following, replacing <PROXY IP> and <PROXY PORT> with the proxy’s IP address and port.

export http_proxy=http://<PROXY IP>:<PROXY PORT>
export https_proxy=http://<PROXY IP>:<PROXY PORT>

For instance, with an HTTP proxy at 192.168.0.10 on port 8080, set:

export http_proxy=http://192.168.0.10:8080
export https_proxy=http://192.168.0.10:8080

Alternatively, you can set these two proxy settings inside the [user] config section in the puppet.conf file: http_proxy_host and http_proxy_port. For more information, see the configuration reference.

Important: Make sure to set these two proxy settings in the user section only. Otherwise, there can be adverse effects.

Finding Forge modules

The Puppet Forge houses thousands of modules, which you can find by browsing the Forge on the web or by using the puppet module search command.

Some Forge modules are Puppet supported or approved modules.

Puppet approved modules pass our specific quality and usability requirements. We recommend these modules, but they are not supported as part of a Puppet Enterprise license agreement. Puppet supported modules have been tested with Puppet Enterprise and are fully supported.

If there are no supported or approved modules that meet your needs, evaluate available modules by module score, compatibility, documentation, last release date, and number of downloads.

To whitelist the Forge to interact with it, the IP is 52.10.130.237. This IP is subject to change without notice.

Searching modules from the command line

The puppet module search command accepts a single search term and returns a list of modules whose names, descriptions, or keywords match the search term.

$ puppet module search apache

When you’ve identified the module you want, you can then install it.

Installing modules from the command line

The puppet module install command installs a module and all of its dependencies. You can install modules from the Forge, a module repository, or a release tarball.

By default, this command installs modules into the first directory in the Puppet modulepath, $codedir/environments/production/modules by default.

For example, to install the puppetlabs-apache module, run:

puppet module install puppetlabs-apache

This command accepts the following options:

Note: Invalid Version Warnings

If any installed module has an invalid version number (anything other than major.minor.patch), Puppet issues the following warning whenever you install a module:

Warning: module (/Users/youtheuser/.puppet/modules/module) has an invalid version number (0.1). The version has been set to 0.0.0. If you are the maintainer for this module, please update the metadata.json with a valid Semantic Version (http://semver.org).

Despite the warning, Puppet still downloads your module and does not permanently change the offending module’s metadata. The version is changed only in memory during the run of the program, in order to calculate dependencies for the modules you’re installing.

Installing modules from the Puppet Forge

To install a module from the Puppet Forge, use the puppet module install command with the full name of the module you want.

The full name of a Forge module is formatted as username-modulename. For example, to instal puppetlabs-apache:

puppet module install puppetlabs-apache

Installing from another module repository

The puppet module command can install modules from other repositories that mimic the Forge’s interface. You can change the module repository for one installation, or you can change your default repository.

The normal default module repository is the Forge, so the default module_repository value is https://forgeapi.puppetlabs.com.

• To change the default module repository, edit the module_repository setting in puppet.conf to the base URL of the repository you want to use.

• To change the repository for a single module installation only, specify the base URL of the repository when you install the module. Use the --module_repository option to set this. For example:

puppet module install --module_repository http://dev-forge.example.com puppetlabs-apache

Installing from a release tarball

To install a module from a release tarball, specify the path to the tarball instead of the module name.

If you cannot connect to the Puppet Forge, or you are installing modules that have not yet been published to the Forge, use the --ignore-dependencies flag. In this case, you must manually install any dependencies.

sudo puppet module install ~/puppetlabs-apache-0.10.0.tar.gz --ignore-dependencies

Note: You can manually install modules without the puppet module command. If you do, you must name your module’s directory appropriately. Module directory names can only contain letters, numbers, and underscores. Dashes and periods are not valid and cause errors when attempting to use the module.

Uninstalling modules

Use the puppet module uninstall command to remove an installed module.

You must identify the target module by its full name, in the username-modulename format.

By default, the command won’t uninstall a module that other modules depend on or whose files have been edited since it was installed.

• To force an uninstall even if the module is a dependency or has been manually edited, use the --force option.
• To uninstall the module while ignoring and overwriting any local changes, use the --ignore-changes option.

Upgrading modules

Use the puppet module upgradecommand to upgrade an installed module to the latest version.

You must identify the target module by its full name, in the username-modulename format. The puppet module upgrade command has several options available:

• Use the --version option to specify a version.
• Use the --ignore-changes option to upgrade the module while ignoring and overwriting any local changes that might have been made.
• Use the --ignore-dependencies option to skip upgrading any modules required by this module.
