Spec score 8.1 #15 of 49 in Patch Management Software

What it is

Uyuni is an open-source configuration and infrastructure management tool for administering many machines. It deploys patches and packages through assignable software channels and repositories, and provisions hardened operating-system templates to bare metal, virtual machines, and containers. Its server acts as a Salt Master, registering and managing Salt clients. Documented clients include SUSE Linux Enterprise, openSUSE, Red Hat Enterprise Linux, CentOS, Oracle Linux, Ubuntu, Debian, Amazon Linux, AlmaLinux, and Raspberry Pi OS. These systems can be on-premises or in public, private, hybrid, and multi-cloud environments. Uyuni checks public security-patch status, matches subscriptions, and runs OpenSCAP compliance checks. Role-based access limits users to authorized actions and resources. Prometheus and Grafana integration provides server, proxy, and client monitoring. VMware vSphere hosts can be inventoried through the VMware API. Uyuni is available through web, API, Linux, and self-hosted deployments, with drift detection, policy as code, and compliance reporting.
