What is a node in Puppet?

What is a node in Puppet?

A node definition, also known as a node statement, is a block of Puppet code that is included only in matching nodes’ catalogs. This allows you to assign specific configurations to specific nodes. Put node definitions in the main manifest, which can be a single site. pp file, or a directory containing many files.

What is site PP in Puppet?

The Puppet site manifest (site. pp) is the main file that Puppet uses to define global system configuration.

Where are Puppet manifests stored?

/etc/puppet/manifests
Puppet programs are called manifests. Manifests are composed of puppet code and their filenames use the . pp extension. The default main manifest in Puppet installed via apt is /etc/puppet/manifests/site.

What is a Puppet role?

Puppet is a cross-platform client-server based application used for configuration management. It handles the software and its configurations on multiple servers. This feature allows the software to configure those systems using files called manifests.

What is Puppet module?

Puppet modules are a collection of manifests and data, which can include facts, files, and templates. Modules help you organize and reuse Puppet code by enabling you to split the code into several manifests. With the exception of the main site.

What is a class in Puppet?

Classes are named blocks of Puppet code that are stored in modules and applied later when they are invoked by name. You can add classes to a node’s catalog by either declaring them in your manifests or assigning them from an external node classifier (ENC).

What is init PP in Puppet?

The init. pp manifest is the main class of a module and, unlike other classes or defined types, it is referred to only by the name of the module itself. For example, the class in init. pp in the puppetlabs-motd module is the mot d class.

What is hiera in Puppet?

Hiera is a built-in key-value configuration data lookup system, used for separating data from Puppet code. About Hiera. Puppet’s strength is in reusable code. Code that serves many needs must be configurable: put site-specific information in external configuration data files, rather than in the code itself.

Where does Puppet look for modules?

The modulepath can include relative paths, such as ./modules or ./site . Puppet looks for these paths inside the environment’s directory. The default modulepath value for an environment is the environment’s modules directory, plus the base modulepath. On *nix, this is ./modules:$basemodulepath .

How do you test Puppet manifest?

You can test your manifests’ syntax with puppet parser validate, verify their code style with puppet-lint, test modules logic and behaviour at catalog level with rspec-puppet, and check the actual effect of a Puppet run on dispensable virtual machines managed by a tool like Vagrant.

Which is better chef or Puppet?

To use an analogy, using Puppet is like writing configuration files whereas using Chef is like programming the control of your nodes. If you or your team have more experience with system administration, you may prefer Puppet. On the other hand, if most of you are developers, Chef might be a better fit.
