How to add static routes via cloud-init to atomic host

Issue

  • How to install static routes via cloud-init to a newly installed atomic host ?

  • We currently have this in the meta-data:

instance-id: atomic_01
local-hostname: hostname
network-interfaces: |
  auto eth0
  iface eth0 inet static
  address 10.10.10.10
  netmask 255.255.255.192
  gateway 10.10.10.1
  auto eth1
  iface eth1 inet static
  address 10.10.10.11
  network 10.10.10.0
  netmask 255.255.255.0
  broadcast 10.10.10.255
  dns-nameservers 10.10.10.2 10.10.10.3
  dns-search localdomain
bootcmd:
  - ifdown eth0
  - ifup eth0
  - ifdown eth1
  - ifup eth1

which configures the interfaces correctly but we can't manage to setup static routes correctly using cloud-init.
