What Is Puppet?

Puppet is a configuration management tool used to deploy, configure and manage servers. Perform the following functions:

  • Configure different settings for each host and continuously verify and confirm that the required configuration is in place and is not modified (if changed, Puppet will return to the required configuration) on the host.
  • Provide control over all machines configured so that a centralized change (based on the master server or repository) is automatically propagated to all.

Why do we use Puppet?

Puppet is one of the most popular configuration management tools in the IT world today. It is also being widely used in Fortune500 companies. Most companies that use DevOps methodologies lean towards the use of Puppet. There are several reasons to explain why it is standing out compared to other configuration management tools, such as the chef:

  • Puppet provides more support for the platform. For example, here are the platforms you can manage using Puppet:
  • Debian / Ubuntu
  • Microsoft Windows
  • Redhat, Centos, Fedora
  • MACOS X server
  • Puppet has better documentation
  • Unlike other configuration management tools,

Puppet After deploying A configuration on any system, continues to verify these settings after certain intervals. These ranges can also be modified by you. Puppet is being used by some of the leading organizations in the industry, such as Google, Red Hat, etc. Puppet helps DevOps system administrators and professionals work faster and smarter

Features of Puppet System

The following are the most important features of Puppet.

Idempotency

Puppet supports Idempotency which makes it unique. Like Chef, in Puppet, you can safely perform the same set of settings several times on the same machine. In this flow, Puppet verifies the current state of the destination machine and will only make changes when there is a specific configuration change. Idempotency helps to manage any particular machine throughout its life cycle, from the creation of the machine to changes. Machine configuration until the end of its life. The Puppet Idempotency function is very useful for keeping the machine updated for years, instead of rebuilding the same machine several times when a configuration change occurs.

Cross-platform

In Puppet, with the assistance of Resource Abstraction Layer (RAL) that utilizations Puppet assets, you can coordinate the predetermined framework design without stressing over the subtleties of the execution and how the arrangement order will function inside the framework, which is characterized. in the basic arrangement document.

What are the Puppet versions?

Puppet comes in two versions:

  • Open Source Puppet: This is a basic version of the Puppet configuration management tool, which is also known as Open Source Puppet. It is available directly on the Puppet website and is licensed under the Apache 2.0 system.
  •  Puppet Enterprise: the commercial version offers features such as compliance reports, orchestration, role-based access control, GUI, API and command-line tools for effective management of us.

Puppet architecture

  • The puppet slave represents the facts he sends to a puppet master. These facts are usually pairs of key/value data that provide some aspects of the status of the slave, such as its uptime, operating system, IP address and more:
  • Puppetmaster uses the facts sent by the slave and builds a catalog that is as a map of how to configure the slave. In other words, a catalog is simply a document that has the desired status for each resource that the Puppet Master manages in a slave.
  • The Puppet slave transmits that the configuration is complete according to the catalog that can be seen on the control panel.
  • Assume that a user or group has a file that Puppet manages, and then the resource of the file will automatically require them. The unique power of Puppet software is that it can create its own types of resources.

Advantages of puppet over other tools

  • Most configuration management tools generally implement the required configuration on a machine and leave them as they are. But the puppet continues to verify the configuration at a specific interval (which you can modify as necessary).
  •  Puppet defines the configuration of a host with the help of a language that is very easy to learn and is used only for this purpose. Puppet is used by the main players in the industry, such as Google, Red Hat, etc.
  •  Largest open-source developer base
  •  A large number of platforms are compatible with puppets
  • It works very well even when it is implemented in a large infrastructure (thousands of hosts manage)
