What is YAML?

YAML (YAML Ain't Markup Language) is a human-friendly data serialization format. It uses indentation and minimal punctuation, making it easy to read and write. It is widely used for configuration files (Docker Compose, GitHub Actions, Kubernetes, Ansible).

YAML vs JSON — key differences

YAML is a superset of JSON — all valid JSON is also valid YAML. YAML additionally supports comments (#), multi-line strings, and anchors (& and *) for reusing values. JSON is more portable for machine-to-machine communication; YAML is preferred for human-edited configuration.
