Description
Hi HN,I made a tiny tool called YAML Validator that checks your YAML files with one Docker command — no installs, no setup, no excuses.It does:- Syntax checks- yamllint linting- checkov security scanning- All in one lightweight, zero-config container---------------------------------------------------------How to use:docker run -v "$(pwd):/data" pooyanazad/yaml-checker <yaml-file>Optional alias (for .bashrc / .zshrc):alias ytest='docker run -v "$(pwd):/data" pooyanazad/yaml-checker'Then simply call:ytest sample.yamlYAML powers CI/CD, configs, infra ,and breaking it is too easy. This aims to catch syntax, style, and security issues early with minimal friction.I’d love feedback, ideas, or edge cases to test.---------------------------------------------------------GitHub: https://github.com/pooyanazad/YAML-validator---------------------------------------------------------Thanks for reading!Pooyan

Yes It is a straightforward Docker container packaging existing open-source command-line tools like yamllint and checkov with a shell script wrapper.
