Y U NO Interpolate?

variable "cassandra_cluster_name" { default = "${join('-', ['foo','cassandra', var.environment])}" }

Hi! I have a terraform_remote_state question. I'm trying to access the state output from a project, but I realize the project is generated via two runs of a single module. Therefore, I have the output listed twice in the state. each with a different result. Is there any way to reference them separately? Or am I going to need to refactor this into two separate state files?

how/why are you needing to run a single module twice to get to a completed state?

@abtreece I'm just calling the same module twice from a main.tf with different variables passed in

in order to stand up two different versions of the same thing?

in this case, to generate an IAM role in two different AWS accounts

it may just be easier to forego the module and generate the resources directly in main.tf

w/out knowing more about what you're doing I would probably separate the configs for the different accounts into their own dirs so they have their own state

Yeah I think that's the easiest path

not a big deal, just not at DRY as i'd like

I would also consider making a module of your IAM role config and then ref'ing that in the two configs

that would get you back to DRY

.oO - Why does Hashicorp hate variables so much

I can still use my IAM module that's already written. But instead of calling it twice from one project, just use two separate projects

with separate state files

yes. then you can resource those state files wherever as needed

I'll go that route. thanks for the guidance

anytime

too bad you can't reference anything deeper in the state files than a single output -- all the data is in there

I suppose you could also try to use outputs, but if you're reusing the config for different vars you may end up with strange behavior

yeah - totally not worth it in this case. just a few extra lines of code and one more consul k/v

so, I must be confused. Where am I allowed to use interpolations and where am I not? I can’t seem to figure it out myself

No in variable defaults, and apparently also not in template file variable passing

only in resource definitions?

only on Wednesdays?

AFAIK interpolation can only be used on things that are rendered. IDK about Wednesdays

Can someone familiar with Terraform take a look at my changes here: https://github.com/hashicorp/otto/pull/519 where a fix a bug that prevent's Otto's master branch from building due to a change in the Terraform API

Specifically https://github.com/hashicorp/otto/pull/519/comm...

It should only take a few minutes for anyone familiar with the terraform.State object…

abtreece: well, apparently not today ;)

I have a "remote-exec" that keeps actually running locally (though console output says "(remote-exec): Connected!") anyone seen this before?
