Course content

4 sections • 17 lectures • 1h 20m total length

  • What is an YAML3:44

    Learn how YAML, a human-readable data description format (not a programming language), simplifies config files and is used in Kubernetes, Ansible, GitHub Actions, Docker Compose, and Helm.

  • Writing your first YAML4:24

    Learn how to write your first YAML file and structure nested data with two-space indentation. Declare strings, numbers, booleans, and lists, and validate syntax with YAML lint.

  • YAML Syntax Explained with Examples6:22

    Explore YAML syntax with hands-on examples, mastering indentation, key-value pairs, lists, and nested maps. Learn to use comments, quotes, and pipe or greater-than notation for multi-line strings.

  • Parse and Visualize YAML with Python6:18

    Parse and visualize YAML with Python by installing PyYAML, loading config files, accessing data as dictionaries, and converting YAML to JSON for automation and config management.

  • YAML vs JSON vs XML – What’s Best3:58

    Compare yaml, json, and xml to understand when to use each data serialization format in development, apis, and enterprise systems.

Requirements

  • No prior experience needed! This course starts from the very basics of YAML.
  • A computer (Windows, macOS, or Linux) with any text editor installed — like Notepad, VS Code, or Sublime Text.
  • Basic understanding of files and folders on your computer.
  • Optional: Some familiarity with tools like Docker, Ansible, or Kubernetes can help, but it’s not required.

Description

Welcome to this complete YAML course for beginners!

If you’ve ever worked with tools like Ansible, Docker Compose, or Kubernetes, you’ve probably seen YAML files everywhere — but maybe they looked confusing or full of strange symbols. Don’t worry! This course will help you go from “What is YAML?” to “I can write and understand YAML like a pro!” — all in simple, clear English, made for non-native speakers.

Let’s start with a bit of history. YAML stands for “YAML Ain’t Markup Language.” It was created in the early 2000s as a human-friendly alternative to XML and JSON. The idea was to make configuration files easy to read, write, and understand, even for people who aren’t programmers. Today, YAML is used everywhere — from Kubernetes manifests and Ansible playbooks to CI/CD pipelines and cloud infrastructure files. Knowing YAML is an essential skill for DevOps engineers, system administrators, and developers.

In this course, you’ll begin by learning what YAML is, how it works, and why it’s used so widely in automation and configuration management. You’ll write your first YAML file, understand the syntax rules, and even parse YAML with Python to see how it works behind the scenes.

Next, we’ll cover the basic YAML concepts — things like scalars, strings, multi-line text, comments, timestamps, and tags. You’ll learn to format your YAML correctly and make it more readable.

Then, we’ll move on to advanced YAML features — such as sequences, ordered mappings, anchors, aliases, and multiple documents. These topics will help you handle complex configurations and reuse YAML efficiently.

By the end of the course, you’ll not only understand YAML — you’ll be confident using it in real DevOps projects with tools like Docker, Ansible, Kubernetes, Terraform, and Jenkins.

So, whether you’re a beginner learning YAML for the first time or a DevOps professional who wants to master it deeply, this course will give you all the knowledge you need — step by step, with clear examples and hands-on practice.

Let’s get started and make YAML simple, powerful, and fun to learn!

Who this course is for:

  • This course is perfect for anyone who wants to understand YAML from the ground up — no matter your background or experience level. It’s ideal for: Beginners in DevOps, Cloud, or IT who often see YAML files in tools like Docker, Kubernetes, or Ansible and want to finally understand them. Developers and System Administrators who need to write or read YAML for configuration files, pipelines, or infrastructure setup. Students or professionals preparing for a career in DevOps, automation, or cloud computing. Anyone curious about YAML, even with no technical background — if you can open a text file, you can learn YAML! Whether you’re building your first Docker Compose file, writing an Ansible playbook, or just trying to read a YAML configuration at work, this course will make YAML simple and clear. If you want to gain a skill that’s used in nearly every modern IT project, and learn it in plain, easy-to-understand English, this course is for you
