Frequently Asked Questions

What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data serialization format using indentation-based structure, popular for configuration files in DevOps tools.

How is YAML different from JSON?

YAML uses indentation (spaces) instead of brackets for structure, supports comments with #, and is more human-readable for complex configurations than JSON.

What tools use YAML configs?

Docker Compose, Kubernetes, Ansible, GitHub Actions, GitLab CI/CD, CircleCI, Home Assistant, and many modern DevOps tools use YAML for configuration files.
