frequently asked

What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used for configuration files in DevOps, Kubernetes, Docker, and CI/CD pipelines.

Is YAML a superset of JSON?

Yes — valid JSON is also valid YAML. YAML is more human-friendly with support for comments, multi-line strings, and less punctuation.
