Frequently Asked Questions
What is YAML?
YAML (YAML Ain't Markup Language) is a human-readable data serialization language commonly used for configuration files (Docker Compose, Kubernetes, GitHub Actions).
Is JSON valid YAML?
Yes! YAML version 1.2 is a formal superset of JSON; any valid JSON document is also valid YAML.
What are the primary syntax differences between YAML and JSON?
YAML relies on Python-style indentation (spaces only) instead of curly braces and brackets, does not require quotes around most strings, and supports comments.
Why are tabs forbidden in YAML indentation?
YAML strictly requires spaces for indentation because different editors display tab widths inconsistently, which could subtly alter hierarchical meaning.
How do comments work in YAML vs JSON?
YAML supports comments using # characters; standard JSON specification does not support comments at all.
What are YAML anchors and aliases (& and *)?
Features that allow defining a reusable block of configuration with an anchor (&name) and referencing it elsewhere with an alias (*name) to avoid duplication.
What are multi-line strings in YAML (| vs >)?
The pipe | preserves literal newlines; the right bracket > folds newlines into spaces, forming a continuous paragraph.
What is the 'Norway problem' in YAML?
In YAML 1.1, unquoted NO was parsed as a boolean false (the ISO country code for Norway); YAML 1.2 resolved this by strictly parsing only true and false.
Why do DevOps tools prefer YAML over JSON for configuration?
YAML is much easier for humans to read, write, and review in git diffs because it omits extraneous quotes, brackets, and commas.
Is the YAML/JSON conversion executed locally?
Yes. Parsing and conversion occur entirely client-side using JavaScript parser libraries without transmitting sensitive configuration data to servers.
