Bug Description

The Flannel overlay network is the default network driver in k8s cluster and is also an option for swarm cluster. It provides different backend implementation for the overlay, among them "udp" and "vxlan". These options are selected by the label flannel_use_vxlan.

The image fedora-21-atomic-5.qcow2 has Flannel version 0.5.0 and the vxlan backend is not working because of a bug in this Flannel version. The previous image fedora-21-atomic-3.qcow2 has version 0.2.0 and does not have this bug. When a k8s cluster is built with the vxlan option, there is no connectivity between the pods.

This bug is fixed in Flannel version 0.5.3:


Attempts were made to build new images with 0.5.3 or later on copr, but the builds are currently failing because of some problem with the golang packages:
