Fedora Fedora Layered Image releases are OCI container images made using the Fedora base packages that will be updated on a two-week release cycle that aligns with the Fedora Atomic release updates. Fedora Layered Image releases will work not only with Docker but with other popular container runtimes that support the Open Containers' OCI specification.
More background information on Fedora's layered image goal can be found via this Wiki page. Among the software making use of Fedora Layered Images are Cockpit, Kubernetes, the GNU toolchain, and more than 20 layered images are said to be in their works for the next release.
