I have written a cloudconfig-lxd utility that configures LXD containers by applying
cloud-config files, in the format used by cloud-init, using the LXD API.
It does not require that the guest OS has cloud-init installed.
It can be used as a Go library or as an executable.
I use it both ways, and I’ve converted my container configuration procedures to this.
The following cloud-init modules (sections) are supported and applied in this order:
write_files (only plain text, without any encoding)
cloudconfig-lxd apply [-ostype <ostype>] -i <instance> <cloud-config-file>...

I hope the instructions are clear. Let me know if anything needs clarification.
