Puppet is an open-source deployment and configuration management tool. Its popularly used on Windows and Linux to facilitate the functioning of different application servers at once. However, you can still utilize Puppet on various other platforms such as Mac OS servers, IBM mainframe, and Cisco switches.
Just as is the case in various other DeOps programs, Puppet does other things apart from automating system administration. It converts human workflow and allows developers and system administrators to collaborate. Programmers can write, test, and initiate applications without having to wait for Ops staff to deliver the required resources.
The configuration management tool syntax in Puppet is separated from the basic applications and operating system’s syntax. This allows you to expound high-level approaches such as application, user, and service. Puppet translates high-level approaches in the software configuration instructions and operating system. Puppet displays everything as data.
That is the current node state, the anticipated end state, and the actions required to change from one to the other. Puppet managed server instances take in a list of relationships and resources, compared it with the expected system state, and executes the changes required to ensure the system is compliant with the perfect state.
You can utilize these programs to facilitate the management of services, software, and configuration on various systems to finalize system configurations in code and this can be challenging. Puppet enables users to control this complexity by writing reusable, easy to refactor, and easy to set up code. You can accomplish this easily through the use of Puppet profiles and roles. These categorize your code on three levels. These are:
These are normal modules that oversee one particular technology such as apache/puppetlabs
These are wrapper classes that utilize different component modules to set up a layered technology stack. For instance, you can create a profile to configure Jenkins, the constant integration application with its automated tasks and web front end.
These are Wrapper classes that utilize multiple profiles to develop a complete system configuration. With the Jenkins role, for example, the server should also have standard roles such as base web server profile and base operating system profile. The latter can decide that the server should be operating under Ubuntu 16.04.2 while the former can declare that the server should utilize Nginx.
More languages, tools, processes, and profiles may appear to be complex while in reality, it grants you space to develop realistic business-specific interfaces for system setups. This eases the use of ranked data and refactoring.
It also makes system configurations easy to read. Think about profiles and roles as a pattern for developing your Puppet controlled systems and expect them to transform over time. Remember, these shouldn’t be mistaken for straitjacket for your servers’ layout.
Are you interested in learning Puppet? Here are some Puppet courses you can enroll in

- Apply Puppet code to set up the set up
Mastering Puppet for Large Infrastructures
This course is designed for learners with intermediate-level knowledge on Puppet. If you’re a developer or system administrator working in production environments and searching for the ideal way of using Puppet in enterprise surroundings this course will be ideal for you.
- Launch a code repository for your project and oversee module dependencies
- Incorporate features to accomplish redundancy and optimize performance
- Set up Puppet server infrastructures by using varying components and methodologies
- Distribute specific reservation components for servers to guarantee fast and reliable data delivery
- Gain knowledge on trigger alerts and notifications for notable Puppet events
- Execute orchestration using Hiera and mcollective for management of data
- Use some best tips and practices on how to troubleshoot problems that may arise.
- Write dynamic Puppet code tests to guarantee appropriate code delivery to Puppet master servers
This course will teach learners how to regulate intricate environments and networks with robust and flexible automation and coding language. If you’re interested in regulating your systems and network with the convenience of a scripting language, Puppet is all you need. This course will take you through the configuration process and you’ll begin by learning about the Puppet infrastructure such as Puppetmasters and agents.
Later, learners will be taught about the Puppet run cycle before going through the Puppet language which shall include: the simple application of Puppet types and Puppet manifest, as well as the application of conditional logic in Puppet. This course is specially designed for professionals with a basic understanding of hardware and configurations. You don’t need a previous understanding of Puppet to enroll.
- Generate analyses and reports with Puppet
- Utilize Puppet code to oversee IT infrastructure
Mastering Puppet the DevOps way by School of DevOps®
This is one of the most comprehensive courses in Puppet. Learners will understand how to write infrastructure as code and oversee it at scale with Puppet. This course is specially designed for systems operations personnel who are interested in learning how to oversee infrastructure at scale. If you’re a developer and are looking forward to configuring consistent environments and software delivery with automation, this course will come in handy.
People who are interested in becoming DevOps professionals are also encouraged to enroll in this course. Infrastructure as a code is among the foundations of the DevOps Automation toolchain. Puppet was the inaugural tool among the four major configuration management tools which include Chef, Saltstack, and Ansible.
It’s also the swiftest configuration management system that offers a simple Domain Specific Language to describe the state of resources. It also executes heavy tasks of overseeing underlying platform-specific operations on its own, giving users increased levels of abstractions that scripts.
- Analysis of Puppet Enterprise
- Master infrastructure as a code and other related concepts such as convergence and idempotence
- Learn roles and profile design patterns
- Understand Puppet’s DSL and the best practices to write Modules, Manifests, and Node Classification
- Learn how to use Hiera to externalize properties
- Create robust data-driven modules with Templates and Parameters
- Overseeing different environments such as Stage, Dev, Production, and QA
- Configure Nodes and Puppet Master and apply configurations with a centralized configuration management system
- Use Continuous Integration tool for integration and distribute applications with Puppet
Getting Started with Puppet
In this course, learners will learn how to use Puppet to automate IT configuration. To enroll in this course you will need a basic understanding of Linux administration. This course is designed for everyone interested in automating IT configuration rather than setting up servers manually. If you’re a Linux system administrator, this course will expose you to various ways of using Puppet in your IT infrastructure.
- Leverage Puppet in the IT infrastructure management
- Understand Puppet and establish how it operates
