Frequently Asked Questions
What YAML validation modes are available?
Generic YAML, Kubernetes, Docker Compose, GitHub Actions, GitLab CI, Azure Pipelines, OpenAPI, and Ansible. Each mode adds structure checks specific to that platform.
Does this replace yamllint?
This tool catches common YAML syntax errors and structure issues. For comprehensive linting in CI/CD pipelines, also use yamllint or your platform's native validation tools.
Why is my Kubernetes YAML failing validation?
Common causes include: missing apiVersion/kind/metadata fields, incorrect indentation, tabs instead of spaces, or unsupported API versions.
