<!-- Self Contained or System Wide Change Proposal?
Use this guide to determine to which category your proposed change belongs to.
 
Self Contained Changes are:
* changes to isolated/leaf package without the impact on other packages/rest of the distribution
* limited scope changes without the impact on other packages/rest of the distribution
* coordinated effort within SIG with limited impact outside SIG functional area, accepted by the SIG
 
System Wide Changes are:
* changes that does not fit Self Contained Changes category touching
* changes that require coordination within the distribution (for example mass rebuilds, release engineering or other teams effort etc.)
* changing system defaults
 
For Self Contained Changes, sections marked as "REQUIRED FOR SYSTEM WIDE CHANGES" are OPTIONAL but FESCo/Wrangler can request more details (especially in case the change proposal category is
improper or updated to System Wide category). For System Wide Changes all fields on this form are required for FESCo acceptance (when applies). 
 
We request that you maintain the same order of sections so that all of the change proposal pages are uniform.

Move to ImageFactory For Cloud Image Creation

Summary

Create images using Anaconda in Koji rather than appliance-creator. Allows non-scratch builds with fedmsg integration for upload service, and also could produce official Docker images.

Owners

Current status

Detailed Description

Jay Greguske recently added a feature to koji that allows it to create full system disk images using Image Factory. These images can be output both as raw and qcow2 disk images, as well as OVA/OVF bundles compatible with OVirt, VMWare and RHEV-M. They are created by running Anaconda kickstart installs in virt containers and then packaging/encapsulating the results.

Benefit to Fedora

By using Anaconda itself to generate the image we eliminate the gap between the tooling used to generate cloud images (currently appliance-creator) and the tooling used to generate bare metal and "normal" virt images (Anaconda). Using Anaconda running inside of virt containers also eliminates any dependency on kernel-level features of the build system hosts. (e.g. - If we want to build a cloud image using a newly introduce or newly updated filesystem, we can do that.) Finally, using Anaconda means that we are coupled to a tool that is already essential to any given release and can be expected to work.

Scope

  • Proposal owners: The Image Factory support in Fedora koji has already landed and images are already being built using this technique. The work for F21 should mainly involve making sure that the existing cloud kickstart files work when run directly by Anaconda and making any chances needed to ensure that they do.
  • Other developers: N/A (not a System Wide Change)
  • Release engineering: N/A (not a System Wide Change)
  • Policies and guidelines: N/A (not a System Wide Change)

Upgrade/compatibility impact

How To Test

Build images inside of koji using the newly added Image Factory support. Deploy these images on the target cloud/virt environments and test for basic functionality and parity with existing appliance-creator based images.

User Experience

N/A (not a System Wide Change)

Dependencies

None that we are aware of. If Anaconda can be used to generate a working virtual machine image, the Image Factory support in koji can be used to create one.

Contingency Plan

  • Contingency mechanism: Continue using appliance-creator
  • Contingency deadline: TBD
