# Zincati

[![crates.io](https://img.shields.io/crates/v/zincati.svg)](https://crates.io/crates/zincati)

Zincati is an auto-update agent for Fedora CoreOS hosts.

It works as a client for [Cincinnati] and [rpm-ostree], taking care of automatically updating/rebooting machines.

Features:

 * Agent for [continuous auto-updates][auto-updates], with support for phased rollouts

 * [Configuration][configuration] via TOML dropins and overlaid directories

 * Multiple [update strategies][updates-strategy] for finalization/reboot

 * Local [maintenance windows][strategy-periodic] on a weekly schedule for planned upgrades

 * Internal [metrics][metrics] exposed over a local endpoint in Prometheus format

 * [Logging][logging] with configurable priority levels

 * Support for complex update-graphs via [Cincinnati protocol][cincinnati-protocol] (with rollout wariness, barriers, dead-ends and more)

 * Support for [cluster-wide reboot orchestration][strategy-fleetlock], via an external lock-manager
