Fedora Atomic is a sub-spin of the Cloud product in Fedora that is an implementation of the Atomic Host pattern defined by http://projectatomic.io
See the original change: https://fedoraproject.org/wiki/Changes/Atomic_Cloud_Image as well as the updated https://fedoraproject.org/wiki/Changes/AtomicHost
The fedora-atomic-docker-host.json
file is the core manifest
defining what goes into the host (ostree) content.
The rpm-ostree
tool is invoked inside Fedora rel-eng; see:
https://git.fedorahosted.org/cgit/releng/tree/scripts/run-pungi#n48
This git repository holds the core manifest file
fedora-atomic-docker-host.json
that is used for that process.
That tree lands in one of the versioned repositories here: http://dl.fedoraproject.org/pub/fedora/linux/atomic/
Cloud (VM) images are generated inside Koji (using ImageFactory ->
Anaconda), using the tree content (note use of the ostreesetup
Kickstart verb).
The images are started via the above releng git repository, and a list of Koji tasks can be found here:
