Can Vagrant attach CD/DVD isos to the VM at build time?

[greeneg]

Working on emulating our production build approach using cloud-init in the VM and need to see if I can attach and detach an ISO at boot for the CIDATA content for it. I don't see an example for this with the provider, so I'm wondering if it is supported

Hi,
There are two parts to your question.

Can Vagrant attach CD/DVD isos to the VM?

Yes, Vagrant can attach disks to VM. Refer Documentation Disks
But, the UTM provider currently does not support adding disks. Please open a feature request if this is needed.
Please note the Disks config will add CD/DVD to VM at all times not just initial boot. So this might not be the best way to get cloud-init working.

Does Vagrant support attaching cloud-init config ?

Yes, Vagrant supports cloud-init via inline content or file. Refer Documentation cloud-init
But, the UTM provider currently does not support cloud-init. Please open a feature request if this is needed.
Please note that you need to have a Vagrant box with cloud-init support for this to work. Vagrant just adds the file.

if you are looking to add cloud-init during the VM build time, please check out UTM Packer cloud builder.
The cloud builder supports adding a cloud-init file as the iso file to the VM at boot time.

What my use case is is that we have an existing template that has a CD/DVD drive added, but would like to attach a custom generated ISO in the DVD drive at boot for the cloud init data, and after the cloud init phase has completed, detach/eject the ISO from the drive. This would allow the CIDATA content to be fed to the system during boot up so it can apply the IP info to the system

What you described is exactly what happens in UTM Packer cloud builder.
If you want to use cloud-init in Vagrant then you should pass it has file (Not yet supported)

For your use case, I think starting with Packer to build the VM box and then use it with Vagrant tp manage that VM.
