Fedimg is a Python-powered service that was built to make Fedora Cloud images available on popular cloud providers, such as Amazon Web Services (AWS), Rackspace, and Google Compute Engine (GCE). It runs on the Fedora infrastructure, where it takes advantage of Fedmsg. Fedimg saves Fedora engineers and developers from having to manually register every newly built Fedora Cloud image with cloud providers. Every base or atomic Fedora Cloud image successfully built in Koji is picked up by Fedimg -- whether it's a development build or an official release.


  • Automatic uploads, triggered by activity on the Fedmsg bus

  • Registers images as both paravirtual and HVM, when appropriate

  • Images with names containing 'atomic' are treated as Atomic images, and registered as such

  • All "heavy lifting" (like downloading and uncompressing raw images) is done ~in the cloud~

  • Emits fedmsgs, providing upload status and image info

  • Works with AWS EC2, with additional services to be added in the future

  • Packaged for EPEL 7 (yum install python-fedimg) and available on PyPI
