vendor-data is not implemented by nocloud with a seedfrom parameter

[Johann Queuniet]

I'm trying to implement the NoCloud datasource for a diskless bare-metal cloud, using command-line parameters. The NoCloud documentation specifies /vendor-data is supported, but booting a server results in queries for meta-data and user-data only, no attempt is made for vendor-data.

Reading the code, it doesn't seem like it is implemented for seedfrom parameters at this time.
See the block around https://git.launchpad.net/ubuntu/+source/cloud-init/tree/cloudinit/sources/DataSourceNoCloud.py#n143

Hi Johann,

Thanks for using cloud-init and for filing this bug! You're correct, this is not currently supported, and it would be a good addition. Would you be interested in contributing such a change?

Thanks!

Dan

Hi Dan,

Sure, I'll take a look at the contributor docs, my company is probably going to need this anyway.

Thanks,

Great! https://cloudinit.readthedocs.io/en/latest/topics/hacking.html has the details of how to get started, and https://cloudinit.readthedocs.io/en/latest/topics/code_review.html has info on the code review process you'll need to go through.

I'll also draw particular attention to the Asking For Help section in that latter doc; if you want assistance figuring out how to go about this, please don't hesitate to reach out!
