Mastering Ansible builds a realistic three-tier application — NGINX, Apache2, Python, and MySQL on Ubuntu — from scratch, adding complexity one lecture at a time instead of front-loading theory.

Six Stages, One Growing Application

The course runs through initial setup, building the application environment layer by layer, refactoring for modularity, optimizing execution time, and finally troubleshooting and testing the finished configuration.

What You'll Learn

  • Running ad hoc commands and writing deployment playbooks
  • Structuring roles with tasks, handlers, files, templates, and default variables
  • Building operational playbooks for cluster status checks and restarts
  • Optimizing and troubleshooting playbook execution

It's free, aimed at beginners with basic Linux knowledge, and includes lecture notes with documentation links and codebase snapshots at each stage.

Who teaches Mastering Ansible? Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.

Frequently asked questions

What are the prerequisites for enrolling in the course?
Before enrolling in this course, it is beneficial to have a basic understanding of Linux command line operations and familiarity with YAML syntax. The course does not cover these prerequisites in detail, but they are essential for understanding how to work with Ansible effectively.
What kind of project will I build during the course?
During the course, you will build a realistic 3-tier web application stack. This involves constructing and managing an environment layer-by-layer using Ansible playbooks, covering tasks such as configuration management, orchestration, and troubleshooting.
Who is the target audience for this course?
This course is designed for system administrators, DevOps engineers, and IT professionals who are interested in learning configuration management and orchestration using Ansible. It is also suitable for those who wish to automate tasks and improve their workflow efficiency.
How does this course differ from other Ansible courses?
Unlike many courses that simply walk through Ansible documentation, this course is structured to build complexity alongside the development of an application stack. It emphasizes modularity, encapsulation, and real-world troubleshooting, providing practical, hands-on experience.
What specific tools or platforms are covered in the course?
The course focuses on Ansible version 1.9.3 and covers tools such as apt for package management, pip for application modules, and mysql_db and mysql_user for database management. It also includes configurations for services like apache2_module and integrates concepts like handlers and notify.
What topics are not covered in the course?
The course does not cover topics outside the scope of Ansible's core concepts and application stack building. It assumes prior knowledge of basic Linux commands and does not delve into alternative configuration management tools or advanced Ansible versions beyond 1.9.3.
What is the expected time commitment for this course?
The course comprises 54 lessons, each building upon the previous one. While the total runtime is not specified, students can expect to dedicate several hours per week to watch lectures, complete exercises, and apply concepts to their own playbooks, depending on their existing familiarity with Ansible.
