Is there a formal plan to remove the template attribute of the template resource? It's currently marked as deprecated, so I presume there is such a plan, though the deprecation occurred 3 years ago and there's no mention of its EOL above.

I ask since I would very much like to make use of this, though I'm hesitant to implement a solution that makes use of it given the Deprecated marker. I have a collection of user submitted templates, that will likely grow organically over time; ideally I could avoid writing a tool that translates these templates to the format understood by the terraform module.

It's a documentation error, template was already removed a long time ago: https://github.com/OpenNebula/terraform-provider-opennebula/pull/170/files#diff-9f084ea0f99816f2b1d2804d73954a89b60f71f29105da84ea55251df14e0237L35

It was removed via PR #170: i.e. when I refactored template resources to share a lot of code parts etc.
The deprecation come from the PR #24

For now template resource share a lot of attributes with VM, virtual machine router and templates.
Defining a whole template in a single attribute text adds some questions around diffs, and then may require more work on the provider side:

• If the user add an extra space to key = value then becoming key = value: should this change trigger a diff in terraform ?
  If not, we need to parse the string, then regenerate a string with a unique formatting in order to help terraform...
• Is there some case where we need fined grained diffs on attributes inside the template ?

Adding a template attribute in the current template resource would imply to add a lot of ConflictWith with attributes that may overlap, or we could just introduce a new resource RawTemplate...

I don't say I made the better choice at this time (when deprecating template) and I'm open to discuss your use case and proposals if you have some ideas 🙂

@treywelsh Aha! That would make sense.

I'd be interested in seeing whether other providers have attributes that expect a template or heredoc, and how they handle whitespace changes.

While I like simplicity of the idea of a RawTemplate resource, there may well be cases where I'd want to either override or supplement a given templatefile with some additional attributes. I'll ruminate on this and will open an issue once I have a fully formed idea.
