What is YAML?
YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used for configuration files. It's the standard format for Docker Compose, Kubernetes manifests, GitHub Actions workflows, Ansible playbooks, and many CI/CD tools.
Common YAML Errors
Indentation: YAML uses spaces (not tabs) for indentation. Inconsistent indentation is the #1 source of errors.
Colons: Always put a space after colons in key-value pairs: key: value not key:value.
Special characters: Strings containing colons, brackets, or special characters should be quoted.
