YAML, JSON, JSONPath tutorial for working with OpenAPI Specification, Swagger Tools, DevOps, Kubernetes – and beyond
Whether you’re configuring Kubernetes deployments, writing OpenAPI specs, or managing CI/CD pipelines, one thing is clear: structured configuration is everywhere. YAML has become the go-to language for defining systems in a readable, developer-friendly way. And if you’re working in modern development or DevOps environments, mastering YAML (and its cousins JSON and JSONPath) is no longer optional—it’s essential.
Ultimate YAML Course: YAML, JSON & JSONPath Zero to Master is a beginner-friendly yet comprehensive course that walks you through these powerful formats step-by-step. Ideal for developers, engineers, and tech professionals who want to work confidently with configuration files, this course gives you both the theoretical foundation and practical know-how to write clean, effective YAML and JSON, and extract data using JSONPath.
You’ll start with a deep dive into JSON—the foundation of many modern web APIs and configuration systems. You’ll learn what makes JSON different from XML, how to structure data properly, and where it’s commonly used in real-world scenarios.

Next up is YAML, where you’ll get familiar with its syntax, data types, and styling formats. The course explores both block style and flow style, as well as YAML-specific features like anchors, aliases, overriding values, and multi-document support. You’ll also cover directives, custom tags, and how to write complex nested keys—everything you need to handle production-ready YAML.
The third section introduces JSONPath, the querying language for JSON documents. It’s like SQL for JSON—an incredibly useful skill when working with logs, APIs, or structured responses. You’ll learn how to extract specific data from JSON files using path expressions and apply this knowledge in tools like Swagger Editor and Kubernetes dashboards.
The course wraps everything together by guiding you through creating real-world documents such as OpenAPI specs using Swagger, and working with tools used in DevOps, cloud computing, and microservices.
