How Do We Create OSTree Repos and Artifacts in Fedora

a more permanent version of this content lives here Introduction NOTE: For background on OSTree check out the docs. When you want to create a new OSTree using rpm-ostree you usually define a few yum repos, and then a json file that says what rpms you want to be composed in the tree.

Once the ostree commit has been created you can then create installer images (ISOs) and cloud/VM images (qcow, etc) from that ostree. [Read More]

Matching Fedora OSTree Released Content With Each 2 Week Atomic Release

Cross posted with this_ Project Atomic Blog post TL;DR: The default Fedora cadence for updates in the RPM streams is once a day. Until now, the OSTree-based updates cadence has matched this, but we're changing the default OSTree update stream to match the Fedora Atomic Host image release cadence (once every two weeks). --- In Fedora we release a new Atomic Host approximately every two weeks.
