Same approach we are using, but with Ansible as our
"bootstrapper/configurer".

I've been successfully able to do the following:

1. generate instance-specific config in the form of a cloud-init file
2. create container
3. take down network on the container by running lxc exec ... ifdown -a
4. generate the container's nw config file on the LXD host via ansible
and push it to the container via "lxc push" (and remove the default
configs if necessary)
5. bring up network on the container by running lxc exec ... ifup -a

The cloud-init config is used to inject the ssh key, setup the ssh
daemon+config and create an ansible-remote user. That user is necessary
for ansible to do later more complex configs by directly accessing the
container over ssh, as you would do for a normal ansible host.

Something cleaner would be cool, possibly integrated in cloud-init itself.

I guess this is somehow possible by creating your custom images and
customizing the templates section of the metadata.yaml file, as outlined
in the last part of this article
