atomic-openshift-node service fails to initialize
Issue
The atomic-openshift-node service fails to initialise correctly due to:
SDN node startup failed: Failed to start plugin: /usr/sbin/ip failed: '/usr/sbin/ip route add 172.17.0.0/16 dev tun0': exit status 2
For some reason docker0 exists in the route table, but not in the tun0 interface:
