In July we put out the first and second releases of Fedora 26 Atomic Host. In this blog post we’ll cover updating an existing Fedora 25 Atomic Host system to Fedora 26. We’ll cover preparing the system for upgrade and performing the upgrade.
The Fedora Atomic Working Group, a major part of Project Atomic, is changing where to join and participate, including mailing lists, IRC, and where to work on Kubernetes integration. Among other things, the Fedora team is becoming more tightly integrated with the rest of Atomic … and vice-versa. Read on for details.
A new Fedora Atomic Host update is available via an OSTree commit:
Commit: 0715ce81064c30d34ed52ef811a3ad5e5d6a34da980bf35b19312489b32d9b83 Version: 26.91
This is the second release for Fedora 26 Atomic Host. This contains a newer version of Kubernetes with fixes for the bug that was in the original release of the Fedora Atomic 26 tree.
Users of built-in Kubernetes on Fedora Atomic Host can now rebase onto the version 26 ref. We will be releasing a few blogs shortly about upgrading your existing hosts.
rpm-ostree is the hybrid image/package system that provides transactional upgrades on Atomic Host. Here are some highlights from version v2017.7, including PolicyKit and experimental overrides support.
