What is YAML?
YAML (YAML Ain't Markup Language) is a human-readable data serialization standard. It's commonly used for configuration files, data exchange, and storing structured data. YAML emphasizes readability and simplicity, using indentation to represent structure.
YAML is widely used in DevOps, CI/CD pipelines, container orchestration (Docker Compose, Kubernetes), and modern application configuration. It's more readable than JSON and more flexible than XML.
Common Use Cases
🐳 Docker Compose
Format Docker Compose files for multi-container Docker applications and services.
☸️ Kubernetes
Format Kubernetes manifests and configuration files for container orchestration.
⚙️ CI/CD Pipelines
Format GitHub Actions, GitLab CI, and other CI/CD pipeline configuration files.
📝 Configuration
Format application configuration files for web frameworks and development tools.
Best Practices
- ✓Indentation: Use spaces (not tabs) for indentation. Standard is 2 spaces per level.
- ✓Validation: Always validate YAML syntax before deploying to catch errors early.
- ✓Consistency: Maintain consistent formatting across all YAML files in your project.
- ✓Comments: Use comments to document complex configurations and explain non-obvious settings.
