Goss

Goss is a minimalist tool that validates server state against declarative YAML tests for configuration and service verification. It is designed for fast execution in CI pipelines and for quick sanity checks on deployed servers. Goss supports many common assertions such as file contents, service status, package presence, and network ports. Because of its simplicity, it is often used as a companion to more comprehensive configuration management and compliance tools. It is useful for developers and operations teams to catch configuration drift and enforce baseline expectations.
