How can I make custom cloud-init script?
I followed Juno manual to create custom virtual machines that declared cloud-init script as mandatory part before I use image inside cloud, create glance image.
They mentioned requirements to virtual machines of different types that include procedure to resize original partition table to fit target vda disk and so on.
I wonder if I can use custom cloud-init script and where is good documentation how to write it?
Can I develop minimal cloud-init procedures that assign ip address only from specific dhcp server and do nothing more?
