@paddycarver: Should this have landed in the Google provider? It looks like an issue with the template_file to me.

[sampcoug]

@rileykarson, I apologize but I am not sure whether it's a problem with the ct provider or the template_file. I have created several variations of the file but none of them seem to run and I can't find the errors either.

[sampcoug]

Hello All, I will raise the issue with https://github.com/coreos/terraform-provider-ct/issues team. Hopefully, the provider maintainer team can help.

[paddycarver]

Hey @sampcoug, I'm not sure I'm following what the question is here. Are you still having this issue?

[melinath]

Sounds like this was not an issue with google_compute_instance.
