About YAML¶
What is YAML?¶
YAML (YAML Ain't Markup Language) is a human-readable data serialization language designed for data exchange between languages with different data structures.
It's often used for configuration files, data exchange, and representing complex data structures in a readable format.
Key Features¶
- Human Readable - Easy to read and write for both humans and machines
- Language Independent - Works across programming languages and platforms
- Hierarchical - Supports complex nested data structures
- Extensible - Can be extended with custom data types
- Secure - Built with security considerations in mind
History¶
YAML was first proposed by Clark Evans in 2001, and was designed together with Ingy döt Net and Oren Ben-Kiki.
The name "YAML" is a recursive acronym for "YAML Ain't Markup Language", emphasizing that YAML is primarily a data serialization language rather than a markup language.
Why YAML Matters Today¶
Infrastructure as Code¶
YAML is the de facto standard for defining infrastructure configurations in tools like Kubernetes, Docker Compose, and Terraform.
DevOps and CI/CD¶
Modern CI/CD pipelines rely heavily on YAML for defining build steps, deployment configurations, and automation workflows.
Cloud-Native Applications¶
As organizations move to cloud-native architectures, YAML becomes increasingly critical for managing complex distributed systems.
Configuration Management¶
YAML provides a clean, readable way to manage application configurations across different environments and deployment stages.
