Download Fedora 25 Atomic Host

Atomic Host is built every 2 weeks or so.

These are the latest official Fedora Atomic Host images, produced 12 days ago.

Atomic Host Images

Fedora Atomic Host is a leading edge base operating system following the Project Atomic model. It is designed around Kubernetes and Docker containers. The images published here showcase that work. Note that the images have passed several levels of automated testing, but are not always subjected to.

  • Please test before using new versions in production. If you do discover a problem, the Atomic Host tools make it easy to flip back to an earlier release — and if that happens, please also help us by filing bugs or submitting fixes.
  • Fedora Atomic Host images are updated roughly every two weeks, rather than on the main six-month Fedora cadence. Because development is moving quickly, only the latest major Fedora release is supported.
  • Note that different Fedora Atomic Host media are subject to different levels of automatic testing. You can learn more about the Atomic project at projectatomic.io. Click here to see the current test status.

Standard Format)

Standard format AMIs are more suitable if you have infrequently accessed data and want to keep storage cost low.
