If i use the Ignition provider as a resource instead of as a data source, it seems to work, but with a warning:

Warnings:

  * module.kubernetes.ignition_user.core: using ignition_user as a resource is deprecated; consider using the data source instead

Is the documentation too far ahead (only data source mentioned), and the code also a little bit behind (resource deprecated without data source being implemented)?

Maybe @mcuadros has an idea what's going on? It's probably related to https://github.com/hashicorp/terraform/pull/11851

Hi @jangrewe, thanks for the issue!

Using exports from a data source need to be specified with the following form: data.TYPE.NAME.ATTR, as documented here: https://www.terraform.io/docs/configuration/data-sources.html

If you change the reference variable to be data.ignition_user.core.id, does that solve the issue for you?

Ouch, thanks @grubernaut - i think my copy & pasting is broken :stuck_out_tongue_winking_eye:
