cloud init custom user-data script not picked up

[eayin2]

I agree, @eayin2 ... the hard-coding of cloud-config is a deal breaker for me ... discourages me from using this most useful effort. OTOH, one can just add the bits required in the hardcoded cloud-config and still run with it.

If I recall correctly, a non hard coded version with an optional python dependency was made in the pull request #56 (comment)

Cause

The reason it's not picked is because -s user-data.sh allows to execute a shell script and not add cloud-config settings, as seen by the Content-Type: text/x-shellscript; charset="us-ascii" boundary.

Feature request

Can you allow supplying a custom cloud-config? If no cloud-config has been supplied, then the default can be used. I think the cloud config should not be hardcoded. By default kvm-install-vm uses NOPASSWD for sudo users. I prefer to provide a hashed password to cloud-init like so:

Example without sudo's NOPASSWD

• The hash password can be stored encrypted with openssl and decrypted interactively before running kvm-install-vm.

Note

Because the hashes are within a heredoc format $-sign has to be escaped by a backslash and not single quotes.

@eayin2, thanks for the update ... and yes, I agree with the maintainer on adding python as a dependency, that can throw up a whole pile of complications (with modules, python versions, and whatnot) ...

If I was to try and address this, I would prefer that people create their ISO cloud-config files, and then supply it as a parameter ... yeah, not smooth, but easier to accommodate in the existing eco-system ... just an optional flag/param to avoid generating ISO and read it from a given path.
