Public bug reported:

We're using CentOS 7.4.1708.
My config (using NoCloud ISO):

#### meta-data
#cloud-config
instance-id: iid-<hostname>
local-hostname: <fqdn>

#### user-data
#cloud-config
write_files:
  - content: |
      # This file is automatically generated by cloud-init!
      172.29.6.61 <fqdn> <hostname>
      127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
      ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    path: /etc/hosts

#### network-config:
version: 1
config:
  - type: physical
    name: eth0
    subnets:
      - type: static
        address: <ip>/16
        dns_nameservers:
          - <DNS1>
          - <DNS2>
        dns_search:
          - <DNS_DOMAIN>
  - type: route
    destination: 0.0.0.0/0
    gateway: <GATEWAY>

I've disabled NetworkManager, and enabled the 'old' network daemon with
chkconfig.

Things that do not work:
gateway is not set (either in the network-scripts/ifcfg-eth0 file or in the routes table). I've also tried to set the default gateway inside the subnet block, doesn't work either.

resolv.conf is empty, except for a comment that cloud-init visited the
file.... :(

I've tried using Config Version 2, but that fails horribly (not even the
IP is set). Even when enabling NetworkManager things go hay-wire real
soon (things like dhclient interfering, having a DHCP address as well as
a static address...)

I only want 3 things:
- simple network configuration with IP, GW, DNS and DNS Lookup Domain
- hostname
- hosts file

I don't care if i have to use the Legacy ENI, Config Version 1 or Config
Version 2, i just want it to work...

Can anyone provide a working example?
