What is Puppet?

Puppet

Puppet is defined as Configuration Management tool utilized for deploying, designing and controlling servers. It plays the below given roles:

ü Characterizing separate setups for every single host, and persistently checking and affirming whether the necessary configuration is set up and is not changed over the host.
ü Scaling-up as well as scaling-down of machines.
ü Giving control over your arranged machines, so an incorporated change is transmitted to all.



Features of Puppet
Here are some of the significant features of Puppet:

ü Puppet helps DevOps by giving computerization and empowering quicker discharges/releases without losing safety or steadiness.
ü It takes into consideration security strategies to be fixed and observed for administrative consistence.
ü By dealing with the setup as code, Puppet guarantees the arrangements are quicker and nonstop transporting of code brings about lower danger of disappointment.
ü It simplifies heterogeneous innovations and binds together them under a particular configuration managing interface.
ü Puppet helps containers and supports the investigation.
ü Tools are given to observe any disparity in functionality so as to increase further knowledge of the arrangements of an item.

Puppet Architecture

Puppet Architecture


Puppet is organized in a master which is agent architecture. The master helps the registers, and the agents survey the master at explicit intervals-of-time to develop their setup.

Agents relate to the master utilizing SSL, so the initial time an agent attempts to interface with the master, the agent authentication should be agreed, and that is normally an origin of issues.



Components of Puppet

Components of Puppet are discussed below:

1)     Manifests
Each Slave has acquired its configuration specifics in Puppet Master that is printed in the local Puppet language. These specifics are transcribed in the language which Puppet can easily comprehend and are named as Manifests. They are made out of Puppet code and their file-names utilize the .pp extension. These are fundamentally Puppet agendas. For instance: You can compose a Manifest in Puppet Master that makes a record and introduces Apache server to all Puppet Slaves associated with the Puppet Master.

2)     Module
A Puppet Module is defined as the collection of Manifests and information, (for example, realities, records, and layouts), and they have a particular index structure, which are helpful for sorting out your Puppet code, since they enable you to divide your code into different Manifests. Modules are independent packs of code and information.

3)     Resource
Resources are the basic unit for displaying framework setups. Every Resource depicts some part of a framework, similar to a particular assistance or bundle.



4)     Facter
Facter accumulates essential data about Puppet Slave, for example, equipment specifics, system settings, OS form & version, IP-addresses, MAC-addresses, SSH-keys, etc. These realities are then made accessible in Puppet Master's Manifests as factors.

5)     Mcollective
It is a structure that enables a few tasks to be implemented in parallel on different Slaves. It accomplishes different tasks like:

ü Interface with bunches of Slaves, regardless of whether in little gatherings or huge distributions.
ü Utilize a communicate model to convey demands. All Slaves get all demands simultaneously, demands have channels joined, and only Slaves coordinating the channel will perform on demands.
ü Utilize straightforward direction-line devices/tools to call distant Slaves.
ü Compose custom stories about your framework.

6)     Catalogs

A Catalog depicts the ideal condition of each supervised resource on a Slave. It is an accumulation of the considerable number of resources that the Puppet Master implements on a particular Slave. Catalogs are organized by a Puppet Master from Manifests and Slave-given information (for example, certainties, testaments, and a domain if given), as well as outside information such as information from an outer Slave classifier, sent-out resources, and capacities. The Master at that point helps the ordered Catalog to the Slave when demanded.
