Section 1: Puppet Course - Beginner Level

This section is tailored for those new to Puppet, introducing you to the basics of configuration management. You’ll start with an overview of Puppet, including the installation of Puppet servers and agents. Lectures cover fundamental Puppet resources such as files, users, cron jobs, and execute commands, providing a solid foundation in managing system configurations. You’ll also learn about establishing seamless server-agent communication, a critical aspect of centralized configuration management.

• Key Topics Covered:

  • Puppet server and agent installation

  • Resource management (cron, files, users, exec)

  • Server-agent communication setup

Section 2: Puppet Training - Intermediate Level

Building on the basics, this section dives deeper into Puppet's capabilities by introducing modules, variables, and control flow constructs. You’ll learn how to utilize Puppet's built-in data types like strings, arrays, and hashes, and control the flow of your manifests with if-else and case statements. Additionally, you’ll explore facts and custom facts, allowing Puppet to collect data about your infrastructure. This section also covers the powerful Puppet Forge, including managing external modules and using R10K for environment management.

• Key Topics Covered:

  • Creating and managing Puppet modules

  • Using variables, arrays, and hashes

  • Control flow with Puppet expressions

  • Puppet Forge and R10K for module management

  • Custom facts for infrastructure insights

Section 3: Puppet Course - Advanced Level

This section takes your Puppet skills to the advanced level, focusing on Hiera for managing configurations dynamically. You’ll explore Hiera’s multi-tier data lookup capabilities, making your Puppet manifests more flexible and reusable. The section also delves into defined types, roles, profiles, and templates, helping you build scalable and modular Puppet code. These advanced techniques are essential for managing large, complex environments efficiently.

• Key Topics Covered:

  • Advanced Hiera data lookups and hierarchies

  • Roles and profiles for modular code management

  • Templates for dynamic content generation

  • Building reusable and scalable Puppet modules

Section 4: Project on Puppet - Fixing Critical IT Issues

In this hands-on project, you'll apply your Puppet knowledge to solve real-world IT challenges. The project begins with setting up infrastructure on AWS, followed by installing and configuring Puppet Master. You’ll then fine-tune agent configurations, manage certificate signing, and deploy testing manifests. The project includes setting up web servers (Apache/Nginx) and databases, allowing you to automate infrastructure setup end-to-end. This is a great way to gain practical experience in using Puppet for IT automation.

• Key Topics Covered:

  • Setting up infrastructure on AWS

  • Configuring Puppet Master and agents

  • Automating web server and database deployment

  • Writing and testing Puppet manifests

  • Troubleshooting and optimizing Puppet configurations

Section 5: Puppet Project on Setting Up a Password-less Infrastructure

This final section focuses on automating user management and setting up a secure, password-less infrastructure using Puppet. You’ll learn how to configure Puppet for managing users and groups, use Hiera for centralized configuration management, and implement security best practices. This project emphasizes building a scalable and secure IT environment with Puppet, equipping you with the skills to handle real-world enterprise scenarios.

• Key Topics Covered:

  • Automating user management with Puppet

  • Implementing Hiera for secure, scalable configurations

  • Setting up a password-less infrastructure

  • Best practices for infrastructure security

Conclusion:

By the end of this course, you’ll have mastered Puppet from beginner to advanced levels, capable of automating complex IT infrastructures with ease. You will gain hands-on experience in creating, managing, and scaling Puppet environments, positioning you as an automation expert ready to tackle real-world challenges in DevOps and system administration.
