Fedora 26 now generally available brings containerized Kubernetes, DNF 2.0, expanded support for application build systems



The Fedora Project, sponsored by Red Hat Inc., announced Tuesday general availability of Fedora 26, the latest version of the fully-open source Fedora operating system. Fedora 26 provides a set of base packages that form the foundation for three distinct editions – Fedora 26 Atomic Host, Fedora 26 Server and Fedora 26 Workstation.

As with previous releases of Fedora, Fedora 26 Server provides a flexible, multi-role platform for datacenter operations, allowing users to customize this edition of the Fedora operating system to best fit their unique needs. New features for Fedora 26 Server include FreeIPA 4.5, which improves running the security information management solution in containers, and SSSD file caching to speed up the resolution of user and group queries.

Planned for availability later this month, Fedora 26 Server also sees a preview of Fedora’s Modularity technology delivered as “Boltron.” As a modular operating system, Boltron enables different versions of different applications to run on the same system, essentially allowing for runtimes to be paired with stable databases.
The latest version of Fedora’s desktop-focused edition provides new tools and features for general users as well as developers. GNOME 3.24 is offered with Fedora 26 Workstation, which includes a host of updated functionality including Night Light, an application that subtly changes screen color based on time of day to reduce effect on sleep patterns, and LibreOffice 5.3, the latest update to the popular open source office productivity suite. For developers, GNOME 3.24 provides matured versions of Builder and Flatpak to make application development for a variety of systems, including Rust and Meson, easier across the board.

Both the Fedora Linux distribution and Red Hat Enterprise Linux are open source technologies. Fedora is built by the community for the benefit of the community. Red Hat Enterprise Linux is developed by Red Hat with the explicit intent of being used as an enterprise IT platform. Developers and Linux enthusiasts flock to Fedora for the latest features and the opportunity to directly collaborate with Red Hat engineering. Banks, stock exchanges, hospitals, and businesses that run the world’s leading websites choose Red Hat Enterprise Linux for the platform’s performance, stability, and security, which lets them implement mature and well-organized IT infrastructures across the enterprise.

Red Hat Enterprise Linux and Fedora enjoy a mutually beneficial relationship that ensures rapid innovation. Fedora benefits from the sponsorship and feedback from Red Hat. In turn, Red Hat can bring innovation to the broader community for collaboration, enabling a rapid maturation of the technology.

“From Linux container advancements to paving the way for modular operating systems, the latest version of the Fedora operating system helps to advance the Fedora Project’s mission of bringing leading-edge innovation to our users,” said Matthew Miller, Fedora Project Leader. “Fedora 26 does this by pairing more stable technologies like Kubernetes with some of the latest advances in open source such, as system containers, helping our users to enjoy these new features from a more solid foundation of established packages and runtimes.”

The size and expertise of the Fedora community make Fedora an ideal incubator and proving ground for features that eventually get incorporated into Red Hat Enterprise Linux. To meet the quality and reliability requirements that make Red Hat Enterprise Linux the choice for mission-critical applications, Red Hat puts Red Hat Enterprise Linux through its own set of tests and quality assurance (QA) processes that are separate and distinct from those of Fedora.

The underlying packages powering these editions have seen numerous improvements, bug fixes and performance tweaks in Fedora 26 to provide an enhanced user experience across Fedora’s use cases. These package improvements include updated compilers and languages, including GNU Compiler Collection (GCC) 7, Go 1.8, Python 3.6 and Ruby 2.4; DNF 2.0, the latest version of Fedora’s next-generation package management system with improved backwards compatibility with Yum; a storage configuration screen for the Anaconda installation program, enabling “bottom-up” configuration from devices and partitions; and updates to Fedora Media Writer that enable users to create bootable SD cards with Fedora for ARM-based devices, like Raspberry Pi

As Linux containers and container orchestration engines expand in popularity, Fedora 26 Atomic Host offers a minimal footprint operating system tailored for running container-based workloads across environments, from bare metal to the cloud. Fedora 26 Atomic Host updates are planned to be delivered approximately every two weeks, to keep pace with upstream innovation. Fedora 26 Atomic Host is available for Amazon EC2, and images for OpenStack, Vagrant, as well as standard installer ISO images are on GetFedora.org. A minimal Fedora Atomic container image is also debuting with Fedora 26.

It also delivers capabilities and features in Fedora 26 Atomic Host include containerized Kubernetes as an alternative to built-in Kubernetes binaries, enabling users to run different versions of the container orchestration engine; and includes the latest version of rpm-ostree which includes support for direct RPM install, a reload command and a clean-up command. It also includes System Containers, a way of installing system infrastructure software, like networking or Kubernetes, on Fedora Atomic Host in a container, and updated versions of docker, atomic, and Cockpit for enhanced container building, system support and workload monitoring.
