Adding Static IP to CoreOS host

My lab has machines with 2 network adapters one gets the IP from DHCP and the other is a static address that i usually configured with  /etc/sysconfig/network-scripts.  
CoreOS is a little different.  You put this information in the cloud-config.yaml file

#cloud-config

coreos:

  units:

    - name: 00-eno3.network

      runtime: true

      content: |

        [Match]

        Name=eno3

        [Network]

        DNS=8.8.8.8

        Address=10.0.0.3/24

        Gateway=10.0.0.1

ssh_authorized_keys:

  - "ssh-rsa xxxxx imported-openssh-key"

Now both IPs are assigned at bootup.  CoreOS auto-magically finds the DHCP server on the second NIC and uses the static IP on the eno3 NIC
