Curriculum
Course Overview & Setup
This introductory section provides an overview of the course structure, introduces your instructor, Gourav Shah, and outlines how to access support and resources. It includes an introduction to the Red Hat Certified Specialist exam (EX407 equivalent) and details on using the course materials effectively. Setup instructions cover setting up a codespaces environment locally with Docker and on Digital Ocean cloud, ensuring you have the environment to progress through the course.
Ansible Fundamentals
This section lays the groundwork by explaining Ansible's core principles: why it's needed, its unique approach to simplicity using YAML, agentless architecture and push model, the concept of Infrastructure as Code (IaC), Idempotence and State Management, and the 'batteries-included' philosophy. Interactive quizzes reinforce your understanding of these concepts and their practical implications. Web quests guide exploration of Ansible's modular capabilities and its relevance in the context of Docker and Kubernetes.
Practical Ansible: Ad-hoc and Playbooks
This section introduces practical Ansible skills. You'll learn to configure Ansible, define inventories, and execute ad-hoc commands to manage servers. Extensive labs cover creating and managing host inventories, using core modules for system configuration, and understanding idempotency. You'll then progress to writing and deploying your first Ansible playbooks to automate base system configurations. Further labs focus on validating, applying, troubleshooting, and debugging playbooks; essential for efficient Ansible deployments.
Mastering Roles and Reusability
This section teaches you how to structure your Ansible code effectively using Roles for enhanced reusability and organization. You'll learn to create roles from scratch, understand the structure of a role, and leverage Ansible Galaxy. Labs walk you through creating roles for Apache and PHP, showing how to manage configurations, dependencies, and nested roles. You’ll build upon your knowledge with nano-projects culminating in deploying a complete application using roles.
Variables, Templates & Advanced Techniques
This section covers advanced techniques for dynamic configuration using variables and Jinja2 templates. You'll explore various ways to manage variables, understand precedence levels, and dynamically configure applications using templates. Labs guide you through separating data from code, using conditional logic and registered variables for flexible workflows, and leverage facts to discover system information.
Leveraging Ansible Galaxy & Role Management
Explore Ansible Galaxy, the vast repository of pre-built Ansible roles. Learn to select and integrate existing roles like HAProxy and MySQL. This section covers applying roles with custom parameters, troubleshooting integration issues, and working with tags to organize your Ansible tasks, roles, plays, and playbooks. A significant nano-project focuses on using Galaxy roles to deploy a complete application.
Controlling Execution Flow & Conditional Logic
Learn to control the execution flow of your Ansible playbooks using conditionals and iterators. This section focuses on conditional logic using 'when' statements and iterating over lists and dictionaries for tasks such as creating multiple users or deploying applications across multiple servers. Through labs, you will learn to make playbooks more robust and adaptable to different operating systems and scenarios, implementing selective execution with tags.
Managing Multiple Environments & Auto Discovery
Explore techniques for managing multiple environments and implementing auto-discovery of services. You'll learn about facts caching, using magic variables for service discovery, and creating staging environments. You'll also learn how to use contra playbooks for rolling back changes.
Secure Secrets Management with Ansible Vault
This section covers the critical topic of securing sensitive data using Ansible Vault. You’ll learn to encrypt files and strings, work with multiple Vault IDs, and manage encryption keys, ensuring secure management of passwords and other sensitive information used in Ansible playbooks. Labs focus on encrypting secrets and integrating Vault into your existing workflows.
Advanced Application Deployments
This concluding section delves into strategies for deploying applications, specifically focusing on creating tasks for database schema updates, handling schema updates, and troubleshooting deployments. You'll learn to build a robust deployment strategy including rolling updates, and the use of pre and post-tasks, task delegation, and waiting for services to become available before proceeding.
