YAML Language

YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used for configuration files, data exchange, and storing structured data.

Key Features:

• Human-Friendly: Uses indentation and simple syntax for readability.
• Structured Data: Supports key-value pairs, lists, and nested structures.
• Language Agnostic: Works with multiple programming languages (Python, Ruby, JavaScript, etc.).
• Extensions: Files use .yaml or .yml extensions.

Basic Syntax:

# Key-value pair
name: John Doe  

# List
languages:  
  - Python  
  - JavaScript  
  - YAML  

# Nested structure
person:  
  name: Alice  
  age: 25  
  skills:  
    - DevOps  
    - Cloud Computing

Common Uses:

• Configuration files (e.g., Docker, Kubernetes, Ansible).
• API request/response formatting.
• Data storage and exchange.

YAML is widely preferred for its simplicity and readability over formats like JSON and XML in configuration management.

YAML Lint:

YAML Lint is a tool or service used to validate and check the syntax of YAML (YAML Ain't Markup Language) files for errors. YAML is a human-readable data serialization format commonly used for configuration files (e.g., in Docker, Kubernetes, Ansible, and CI/CD pipelines).

What Does a YAML Linter Do?

A YAML linter helps:

• Detect syntax errors (e.g., incorrect indentation, missing colons, improper key-value formatting).
• Validate structure (e.g., ensuring lists and nested objects are correctly defined).
• Improve readability by highlighting formatting issues.
• Prevent runtime errors in applications that rely on YAML files.

Why Use a YAML Linter?

• Avoid misconfigurations in critical systems (e.g., Kubernetes, Ansible).
• Ensure consistency in team projects.
• Catch errors before deployment.
