Public bug reported:

cloud-init trunk with the following network config:

network:
    version: 1
    config:
        - type: physical
          name: interface0
          mac_address: "52:54:00:12:34:00"
          subnets:
              - type: static
                address: 10.0.2.15
                netmask: 255.255.255.0
                gateway: 10.0.2.2


renders an ifcfg-interface0 file without a GATEWAY=10.0.2.2

% cat /etc/sysconfig/network-scripts/ifcfg-interface0
# Created by cloud-init on instance boot automatically, do not edit.
#
BOOTPROTO=static
DEVICE=interface0
HWADDR=52:54:00:12:34:00
IPADDR=10.0.2.15
NETMASK=255.255.255.0
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
USERCTL=no


Subsequently, route -n shows that a default gateway is not set.

% route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.0.2.0        0.0.0.0         255.255.255.0   U     0      0        0 interface0
169.254.0.0     0.0.0.0         255.255.0.0     U     1002   0        0 interface0


If you add GATEWAY=10.0.2.2 you see a route like this:

% route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         10.0.2.2        0.0.0.0         UG    0      0        0 interface0
10.0.2.0        0.0.0.0         255.255.255.0   U     0      0        0 interface0
169.254.0.0     0.0.0.0         255.255.0.0     U     1002   0        0 interface0
