Cloud-init in Debian

[James Allsopp <jamesaallsopp@googlemail.com>]

Hi,

Does anyone have an example or tutorial for  using cloud-init with debian images. I'm currently trying to do terraform with kvm, but struggling as although terraform picks up the cloud-init, the fqdn and the ssh key isn't working. I'm trying to use this image https://cdimage.debian.org/cdimage/cloud/buster/20201214-484/debian-10-genericcloud-amd64-20201214-484.qcow2

I'm not entirely sure if this is the correct image or not?

A lot of the instructions online are for ubuntu or red hat.

Thanks

James
