Rocky is an open-source enterprise operating system designed for server and cloud infrastructure. It is a community-maintained Linux server distribution that provides a platform focused on stability and security.
The project is fundamentally a Red Hat Enterprise Linux compatible operating system, maintaining bug-for-bug binary compatibility to ensure identical software behavior. This allows it to serve as an enterprise-grade platform without proprietary licensing.
The distribution covers a broad range of system administration capabilities, including package management via modular repository streams, system hardening through strict access controls, and the management of logical volumes and file systems. It also supports the deployment of containerized servers and the orchestration of infrastructure using agentless automation engines and declarative state configurations.
Administrative tasks can be performed through a variety of tools, including image-based automated installation media, unit-based service management, and the execution of shell scripts for repetitive system jobs.
