Public bug reported:
Originally reported after bug 1577982 was fixed, there is an issue
providing network configuration to the NoCloud datasource via the meta-
data key 'network-interfaces'.
For example:
$ cd /var/lib/cloud/seed/nocloud-net
$ cat meta-data
instance-id: 1470899540
local-hostname: soscared
network-interfaces: |
auto eth0
iface eth0 inet static
hwaddr 00:16:3e:70:e1:04
address 103.225.10.12
netmask 255.255.255.0
gateway 103.225.10.1
dns-servers 8.8.8.8
It should be noted that without providing 'hwaddr' above, you'll be relying on
kernel network or systemd network device naming to have the device named
'eth0'. If it is not named 'eth0', then configuration wont work.
So the two options to do that right are:
a.) provide 'hwaddr' as shown above
b.) provide 'net.ifnames=0' on kernel command line
(https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/).
(Note, when run in lxc, you will get eth0 names consistently and you do
not need the hwaddr or kernel command line).
