cdist vs Uyuni

cdist is a free, open-source configuration management system that applies a defined state to computers through shell scripts and cdist types. It is positioned as an alternative to Ansible, Chef, and Puppet. Types provide the extension mechanism, and the project says their results are idempotent, so outcomes do not depend on call order. cdist uses push mode: source computers connect to targets over SSH and apply configuration, without requiring a central server or an agent on the target. A target needs a POSIX-compatible shell and SSH server, while the source needs a POSIX-like shell, Python 3.5 or later, and an SSH client. The project lists a small core, standard types, and parallel execution. Installation is documented through Git or pip. Supported systems include Linux distributions, BSD systems, Mac OS X, and XenServer. Manuals are available in HTML and man-page formats, with community help through Matrix and IRC.

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.
