Hello, RedHat-hosted Koji servers offer an invaluable service by allowing all of us, package maintainers, to build all of "our" Fedora packages. I guess that that infrastructure is not cost-less for RedHat and and the quality of service is great (for instance, the wait in the queues, before Koji actually builds the packages submitted via the command-line client, is not so long).
As Fedora is pretty advanced in the cloud/virtualisation arena, we could imagine a "Koji Cloud", hosted on VMs offered by volunteers. For instance, I could contribute a few VMs in Europe (hosted on http://www.ovh.co.uk/). Our Cloud SIG (https://fedoraproject.org/wiki/Cloud_SIG) and/or Virt ML ( https://admin.fedoraproject.org/mailman/listinfo/virt and https://fedoraproject.org/wiki/Getting_started_with_virtualization)/RedHat ET (http://et.redhat.com/) colleagues could help designing and implementing the following infrastructure: * VM template/images, ready to be started on the volunteer's servers everywhere in the world, 24x7. - SSH public keys of Koji administrators would be part of the images, so that they can have an easy access to them, just in case. - Those VMs would update themselves automatically. - The containers could be standardised as well. For instance, ProxMox/OpenVZ or Fedora/CentOS with libvirt. * A directory (LDAP, or something less centralised, like the address book of Skype, for instance), keeping track of all those VMs: - with the corresponding last known status; - with the VM configurations (Fedora/CentOS release, CPU, memory, disk usage, etc); - with some rating corresponding to their quality of service (build duration, reliability of the VM, MTBF, etc). * A dispatcher system: - which would route the Koji build requests to available VMs; - collect the outcome of the builds (logs, RPM packages, statistics, QoS, etc) and store them in the current ("centralised") Koji infrastructure. As I am not a specialist of all those technologies, I may have forgotten a lot of things, but you get the idea. Doesn't it sound great? Does it sound realisable? Am I crazy to dream to such an infrastructure? Cheers Denis
