YAML (YAML Ain’t Markup Language)

YAML is a human-readable data serialization language commonly used for configuration files and data exchange between programming languages. The acronym stands for “YAML Ain’t Markup Language,” highlighting its focus on data rather than documents. YAML uses a minimal syntax featuring indentation to represent hierarchical relationships, making it easy to read and write. It supports complex data structures like mappings (hashes/dictionaries), sequences (arrays/lists), and scalars (strings, numbers). YAML is widely utilized in DevOps and automation tools such as Ansible, Docker Compose, Kubernetes, and CircleCI for defining configurations in a straightforward and efficient manner.
