Written 4 months ago by IanDorfman

CoreOS Container Linux, an operating system optimized for scalable, high resilience server stack operation, has officially reached its end-of-life. Fedora has posted the end-of-life timeline on its official site.

Though Small CoreOS iconCoreOS is being discontinued, it is being replaced with an official successor, aptly named Fedora CoreOS. Fedora CoreOS is purpose built for scalable and secure containerized workload operation that CoreOS Container Linux was most used for.

The timeline for CoreOS's end-of-life is as follows:

• Starting now, you can no longer newly subscribe to CoreOS via the Amazon Web Services Marketplace.

• On May 26th, the last updates for CoreOS will roll out. After that date, any discovered exploits and vulnerabilities will no longer be patched.

• On ("or after") September 1st, documentation and resources related to CoreOS will be either deleted or made read-only. In addition, CoreOS downloads will be removed and its images will be removed from AWS, Small Microsoft Azure iconMicrosoft Azure, and Small Google Compute Engine iconGoogle Compute Engine.

For those of you looking to migrate your instance of CoreOS to Fedora CoreOS, Fedora has set up a migration guide. If you don't wish to migrate to Fedora CoreOS but wish to stay on an actively maintained operating system with a similar focus, Fedora has also recommended Small OpenShift iconOpenShift and Flatcar Container Linux as viable alternatives.
