Deprecated extension points and APIs

These APIs and extension points are deprecated, and will be removed in future releases.

Puppet Faces is a private API

The Puppet::Face and Puppet::Indirector::Face classes are private APIs, and we don’t document or support them. Don’t use them. Instead, to develop command line applications that use Puppet’s data:

• Pick a popular, well-maintained Ruby framework for CLI apps, such as Thor or Commander.
• Use Puppet’s public Ruby APIs to access its settings and data. See the developer documentation for information about the classes and methods available for this.
• Distribute your application as a Gem or native package, instead of as a Puppet module.
• To make your command available as a puppet <NAME>-style subcommand, name it puppet-<NAME> and put it in your $PATH. When you call it, you can leave out the hyphen.

Resource type and provider APIs

As of Puppet 5.0, the resource_types API endpoint has been removed. Instead, use Puppet Server’s environment_classes endpoint.

The Puppet.newtype method on the top-level Puppet module is a proxy for Puppet::Type.newtype. The Puppet.newtype method will be removed in a future release. Update any custom resource types to use Puppet::Type.newtype instead.

Miscellaneous APIs

The Puppet::Node::Facts#strip_internal method has been removed as of Puppet 5.0.

Previously, the stacktrace property in HTTP error responses was always empty for security reasons. In Puppet 5, we’ve removed the stacktrace property as it serves no purpose.
