uCore is an OCI image of Fedora CoreOS with "batteries included". More specifically, it's an opinionated, custom CoreOS image, built daily with some common tools added in. The idea is to make a lightweight server image including commonly used services or the building blocks to host them.
Please take a look at the included modifications, and help us improve uCore if the project interests you.
Fedora CoreOS is an automatically updating, minimal, monolithic, container-focused operating system, designed for clusters but also operable standalone, optimized for Kubernetes but also great without it. Its goal is to provide the best container host to run containerized workloads securely and at scale.
Fedora CoreOS is an open source project associated with the Fedora Project.
Ignition is a utility created to manipulate disks during the initramfs. This includes partitioning disks, formatting partitions, writing files (regular files, systemd units, etc.), and configuring users. On first boot, Ignition reads its configuration from a source of truth (remote URL, network metadata service, hypervisor bridge, etc.) and applies the configuration.
Butane (formerly the Fedora CoreOS Config Transpiler, FCCT) translates human readable Butane Configs into machine readable Ignition Configs. See the getting started guide for how to use Butane and the configuration specifications for everything Butane configs support.
An innovative platform for hardware, clouds, and containers, built with love by you.
