What is the current behavior?

When using a custom userdata template file under the worker_group resources options, I noticed that the template is no longer rendering as userdata content on the instance.

If this is a bug, how to reproduce? Please include a code sample if relevant.

worker_groups = [
    {
      name                          = "${var.cluster_name}-wg"
      ...
      userdata_template_file        = "${path.module}/templates/eks_compute_userdata.sh.tpl"
   }
]

The userdata on the instance:

$ cat /var/lib/cloud/instances/i-0xxxxxxxxxxxxx/user-data.txt
./templates/eks_compute_userdata.sh.tpl

What's the expected behavior?

The actually userdata content from the template should be rendered, not the path to the template. This was working before.

Are you able to fix this problem and submit a PR? Link here if you have already.

Not sure. This may be related to the following PR: #883.

Environment details

• Affected module version: v12.1.0
• OS: Ubuntu 18.04

Oops. I feared this would happen.

You need to pass in the contents of a template. userdata_template_file = file("path/to/file.tpl")

The original implementation of userdata_template_file took the contents of a template, not the path to a file. This was accidentally broken in 12.0.0 by #854. #882 was filed about the break and resolved by #883 .

Thanks for the info @dpiddockcmp! That worked as expected.
