pyinfra vs Uyuni

pyinfra is a free, Python-native tool for automating infrastructure across servers. It connects over SSH to run commands concurrently and idempotently, using Python deploys and inventories. Operations can describe a desired host state or issue specific commands, and `--dry` previews per-host changes before applying them. The project says it works from one host to 10,000, with parallel execution and real-time output. Target machines need a shell and SSH, but no agent, daemon, state file, or control plane. Documented connectors include SSH, Docker, Terraform, and the local machine; operations cover package managers, files, services, databases, security, and containers. It runs wherever Python runs, with Mac, Linux, and Windows listed as control systems. Python 3.10 or later is required; pyinfra 3.5.1 and later supports Python 3.10 through 3.13. The software is MIT licensed. The installation guidance recommends keeping pyinfra and its dependencies current and installing as a regular user rather than as root or with sudo. Help is directed to Matrix and Stack Overflow, while bug reports go to GitHub issues.

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.
