4 years ago Fwiw, the distinction between [], {} and null in:
- tags = [] -> nulland
- labels = {} -> nullis also fairly unhelpful.
I can file an extra bug about the fact that terraform claims it doesn't know what the project will be, it seems strange for terraform to claim that it doesn't know the project:
~ project = "$PROJECT" -> (known after apply)That is definitely a known quantity.
This:
+ name_prefix = (known after apply)relates to #5284 -- I was trying to suppress that, but I can't, because attempting to do so triggers that error instead ...
The overall use case for this adventure is being able to easily recognize what is changing.
We're using terraform to make lots of changes, or few changes. But terraform massively multiplies the number of changes it reports to the point that it's hiding the needles in very large haystacks.
Ideally, if I make a single change -- as here I'm just adding a metadata.shutdown-script, I should see a single change to that block (in this case, I'd also expect the metadata_fingerprint change). If necessary, a note that the entire object is being replaced, but no other diff markers.
Having to review each and every line because the tool isn't smart enough to recognize that it isn't changing other things costs us a lot.
(I'm happy to write patches, or have someone else from our group write patches.)

I have pre-existing manually created templates that I kind of like. I'd like to migrate to using terraform w/o losing their characteristics.
(Yes, I understand SCSI is the default today, and the terraform behavior is documented, but it clearly isn't required from gcloud's perspective.)
References
This is in the family of #5283 -- things which do not quite work the way I'd like in that I can't produce the output I'd like the way I'd like / there doesn't appear to be any way to do so using terraform.
