Coreos official websiteAnnounce, container 13linux will end its life cycle on May 26, 2020 and will no longer receive updates. It is strongly recommended that users start migrating workloads to another operating system as soon as possible. Container Linux, the original core OS Linux distribution, was renamed container Linux in 2016.

Early in 2018, Red Hat acquired CoreOS and announced the launch of Fedora CoreOS in June that year as a new upstream release for CoreOS. Fedora CoreOS, a new version of Fedora built specifically to secure and run containerized workloads on a large scale, is a follow-up to Fedora AtomicHost and CoreOS Container Linux. Last month, Fedora CoreOS was finally officially GA.

Container Linux ends its life cycle. Red hat and coreos naturally recommend users to participate in Fedora coreos. They have already providedMigration Guide 。 However, Fedora coreos currently cannot replace container Linux in all use cases:

  • It has not included local support for platforms supported by Azure, Digital Ocean, GCE, Vagrant, and the Container Linux community.

  • The RKT container runtime is not included.

  • Fedora Core OS is as stable as possible, but sometimes it can make regression or disruptive changes to some use cases or workloads.

For the timeline of the end of the life cycle of container Linux, the following instructions are given officially:

  • Effective immediately, the CoreOS Container Linux list on AWS Marketplace will no longer be available to new subscribers.

  • On May 26, a final update to CoreOS Container Linux was launched. Any errors or security breaches found after this date will not be fixed.

  • On or after September 1, published resources related to coreos container Linux will be removed or made read-only. The operating system download will be removed, the coreupdate server will be shut down, and the operating system image will be removed from AWS, azure and Google compute engine.

If Fedora coreos fails to meet the requirements, it is also suggested that flatcar container Linux, a branch of coreos container Linux, can also be considered.
