On behalf of the Fedora Atomic WG and Fedora Release Engineering, I am pleased to announce the first ever Fedora Layered Image Release. From now on we will be doing regularly scheduled releases of Fedora Layered Image content that will match the Fedora Atomic Two Week Release schedule.
Each Container Image is released with the following streams which aim to provide lifecycle management choices to our users:
Name Name-Version Name-Version-Release
Each of the
Name-Version tags will be updated in place with their respective updates for as long as the maintainer supports them and the
Name-Version-Release will always be a frozen in time reference to that particular release of the Container Image.
At this time the following Container Images are available in the Fedora Registry:
registry.fedoraproject.org/f25/cockpit:130-1.f25docker registry.fedoraproject.org/f25/cockpit:130 registry.fedoraproject.org/f25/cockpit registry.fedoraproject.org/f25/kubernetes-node:0.1-2.f25docker registry.fedoraproject.org/f25/kubernetes-node:0.1 registry.fedoraproject.org/f25/kubernetes-node registry.fedoraproject.org/f25/toolchain:1-1.f25docker registry.fedoraproject.org/f25/toolchain:1 registry.fedoraproject.org/f25/toolchain registry.fedoraproject.org/f25/kubernetes-master:0.1-3.f25docker registry.fedoraproject.org/f25/kubernetes-master:0.1 registry.fedoraproject.org/f25/kubernetes-master
We’re targeting 20 more Layered Images before our next release, so keep an eye out for the offerings from the Fedora Project in our rapidly growing registry.
What are Fedora Layered Images?
Fedora Layered Images are OCI Container Images that are built on top of the Fedora Base Image. These images aim to provide verified content built in a way that can be developed on, contributed to, and audited openly by the community. The images are maintained by Fedora Contributors and they will follow a regular two-week release cycle which will include security updates. (Note: Out of band updates will be released for critical security issues as needed)
The original goal of Layered Images was to provide Container Image content to the Fedora user community to help foster new ideas such as Fedora Atomic Host, Fedora.Next and Fedora Modularity. In the early days we targeted creating a reproducible build system for Docker images, but since the idea’s inception, the container technology landscape has changed considerably and instead of targeting only Docker we are now providing a solution that allows our users and contributors choice in their container runtime.
Ultimately we hope to provide content in a way that can highlight the Project Atomic family of technologies as a part of the Fedora Project.
We are currently working on a way to provide browse and search functionality for Fedora Container Images, so please stay tuned for that.
For those interested, the source of this content is provided in DistGit which can easily be searched via the container-specific pkgdb namespace.
Anyone interested in contributing Container Images, please feel free to join in and submit one for Review.
