Ultimate YAML Course : YAML JSON JSONPath Zero - Master

yaml is a lightweight, human-readable data serialization language with a minimalist indentation-based syntax. It offers comparable features to xml and json and is widely used for configuration in cloud.

Trace the evolution from XML to JSON to YAML and compare their roles in data serialization and DevOps configurations.

Discover why YAML offers cross-platform portability and human-readable configuration for DevOps and cloud workflows, with practical examples from Docker, Kubernetes, Prometheus, and CI tools.

Explore YAML tools for formatting, viewing, validating, and converting YAML to JSON, and learn how to edit YAML with Visual Studio Code.

Learn how to add comments in YAML using the hash symbol, including single-line and multi-line commands, and why starting files with three hyphens matters.

Define data in YAML exclusively as key-value pairs, handle spaces in keys, use quotes for keys or values, and ensure unique, case-sensitive keys to avoid duplicates.

Explore writing YAML syntax, focusing on indentation, maps, and case sensitivity, and compare YAML to JSON while building and validating complex YAML files in VS Code.

Explore YAML data types, including strings, numbers, nulls, booleans, maps, and lists, and learn how keys are strings while values may be strings, numbers, nulls, booleans, maps, or lists.

Explore scalar types in YAML—strings, numbers, null, and booleans—how implicit typing and explicit quotes affect JSON conversion across parsers and viewers.

Master YAML objects and arrays by understanding maps, dictionaries, and nested structures; learn how indentation and hyphens define keys, values, and array elements, with JSON equivalents.

Explore how YAML handles strings, when to enclose strings in quotes, and special characters affect parsing. Learn how folded (>) and literal (|) styles preserve or remove newlines.

Explore sequences in YAML, including block and flow styles, and how indentation and hyphen space lists define structure. Learn to nest sequences and compare block versus flow representations.

Discover how dictionaries in yaml organize data as key-value pairs, with strings as keys and scalars or collections as values, illustrated by an application example with loans, technology, and team.

Explore anchors and aliases in YAML, showing how to define and reuse repeating blocks with ampersand and asterisk to reduce duplication, save space, and improve maintainability.

Master yaml anchors and aliases by inheriting properties and using merge keys to override or extend blocks, demonstrated with a maven pipeline example.

Define complex keys in yaml by using a leading question mark for multi-line keys, maintain proper indentation and colon separation, and understand their json equivalents.

Explore how YAML powers AWS CloudFormation templates, comparing JSON and YAML formats, and map resources, properties, and block device mappings to provision infrastructure.

Explore how YAML defines Kubernetes deployments and services with apiVersion, kind, metadata, and spec. See practical YAML patterns, multiple containers, ports, and Kubernetes configuration in DevOps.

Explore a practical YAML example for Azure Pipeline, illustrating parameters, nested arrays and maps, jobs, and runtime variable replacement in a YAML configuration.

Discover how JSON, JavaScript object notation, serves as a lightweight, language independent data exchange format for web development and REST APIs, and how it compares to YAML and XML.

Explore json syntax by defining json objects with string keys and values of types such as string, number, null, boolean, object, and array, including the root object and example.json.

Master JSON arrays by defining them, understanding index-based access, multi-line and single-line representations, and retrieving elements and nested objects with JSONPath queries.

Explore the data types in json: strings, numbers, booleans, null, objects, and arrays. Learn how keys and values work, how strings use quotes, and how nested json and arrays differ.

Learn how JSONPath serves as a query language to extract data from JSON and explore how dollar defines the root while dot and bracket notation navigate keys.

Explore JSON path basics by navigating a sample json object, using dot notation to traverse nested maps like metadata and labels, and locating values such as kind and container port.

Learn how to traverse JSON arrays with JSONPath, using root $, array indexing, and dot notation to access volumes and containers, including nested elements and ports.

Master JSONPath array range techniques to retrieve elements by index and by start:end ranges, apply steps for skipping elements, explore reverse indexing with minus values, and handle out-of-range cases.

Master JSONPath conditional operations to filter data without indexing, using the current element and dot notation. Apply the conditional operator to extract ports and names from nested arrays and containers.
