Why the Puppet is called Puppet?
Well, who knows?
But all we know is, it surely does a lot more than just a puppet.
Puppet consists of a custom declarative language to describe system configuration, which can be either applied directly on the system, or compiled into a catalog and distributed to the target system via the client-server paradigm, and the agent uses system-specific providers to enforce the resource specified in the manifests. The resource abstraction layer enables administrators to describe the configuration in high-level terms, such as users, services, and packages without the need to specify OS-specific commands.
And The result of the same is huge! It ends up helping in deploying, managing, and configuring your servers and mostly, contributing to your DevOps culture. Isn’t that amazing?
Being the favorite tool of so many organizations, it is quite obvious that Puppet will throw a hell lot of interview questions on your way. Hence, here are the top 20 Puppet interview questions that can help you out in your next interview. Have a look!
The Puppet is a configuration management tool that is broadly used for automating the administration tasks. Puppet tool contributes to DevOps culture by deploying, managing, and configuring your servers.
The Manifests are some files in Puppet where the client configuration is specified.
The manifests that are defined in modules can be included in the manifests, making it easier to manage the modules Also, the chosen manifest can be pushed on the specific agent or node.
The Facter is a system profiling library that is used in gathering the system information during a Puppet run. The Facter provides you with information regarding the IP address, version of kernel, CPU, and others.
Puppet Kick allows you to trigger the Puppet Agent from Puppet Master during the run interval when the Puppet Agent sends a request to Puppet Master.
The MCollective is a tool developed by the Puppet labs for server orchestration. MCollective runs thousands of jobs simultaneously using your own or existing plugins.
Puppet tool can be used for managing machines like laptops, desktops, and even workstations.
Beginning with Puppet 2.7.6 it is possible to run on Windows and this ensures future compatibility.
An organization with a huge number of servers can be benefitted by Puppet since it eliminates the need of manual management of the servers.
Puppet can run on unique servers. Although there might be fewer chances of servers being unique since within an organization there are a lot of similarities that exist like the operating system that they are running on.
Puppet Labs is a company interested in solving the Puppet automation problem.
You can upgrade Puppet and Facter by your operating system package management system in 2 ways:
The characters that are permitted in a class and module name are:
You can set variables like $ with the help of Facter.
If you don’t sign a CLA, code contributions to Puppet or Facter can’t be accepted. Puppet users can log in to their GitHub account for signing the agreement on the CLA page.
The codedir in Puppet is the main directory ideal that stores Puppet data and code. The codedir contains environments in which manifests and modules reside.
The puppet.conf is ideal for configuration of the location of codedir with the codedir setting. Puppet Server uses its JRuby-puppet.master-code-dir Setting along with the puppetserver.conf.
Answer: Hiera is a built-in key-value lookup ideal to separate the data from Puppet code. Hiera also stores configuration data in key-value pairs and is ideal to find out the data needed by a specific module for a given node.
Virtual Resources in Puppet are instruments that specify a particular state of a resource. Although, Virtual Resources don’t demand the implementation of the specific state for the resource.
Answer: Puppet is an ideal tool for managing almost any machine. Hence, puppet proves to be a major tool for managing various organizations that have various systems.
