I'm attaching a complete examaple of how to do this. However, I think
that setting the DNS information doesn't currently work. Apparently
cloud-init is expecting a network configuration containing the DNS
settings inside the network interface, something like this:
iface eth0 inet static
dns-nameservers 1.1.2.2 1.2.3.4
dns-search google.com
address 192.168.1.102
netmask 255.255.0.0
gateway 192.168.2.1
auto eth0
But we actually pass them outside of the network interface, like this:
dns-nameservers 1.1.2.2 1.2.3.4
dns-search google.com
iface eth0 inet static
address 192.168.1.102
netmask 255.255.0.0
gateway 192.168.2.1
auto eth0
I need to check it.
