Puppet (tool)

From Wikipedia, the free encyclopedia

Puppet is an open source configuration management tool. It is written in Ruby.

Puppet is a tool for managing the configuration of Unix-like systems, declaratively. The developer provides puppet templates for describing parts of the system, and, when these templates are deployed, the runtime puts the managed systems into the declared state.

Puppet consists of a custom declarative language to describe system configuration, distributed using the client-server paradigm (using XML-RPC protocol), and a library to realize the configuration. The resource abstraction layer enables administrators to describe the configuration in high-level terms, such as users, services and packages.
