• In documents (https://www.infracost.io/docs/usage_based_resources#resource-arrays) I've seen notes for resource arrays and modules. My question is does the wildcard method also work with

for_each

resources? (it's not clear in docs)

It should work for

count

and

for_each

. +1 we should clarify this.

@Alistair (Infracost) it seems the wildcard char in usage-file is not working with for_each. (tested with

infracost/example-terraform/sample1

aws_lambda_function.hello_world

9:33 AM

aws_lambda_function.hello_world["hello"] ├─ Requests 0 1M requests $0.00 └─ Duration 0 GB-seconds $0.00 aws_lambda_function.hello_world["hi"] ├─ Requests 0 1M requests $0.00 └─ Duration 0 GB-seconds $0.00

Oh sorry my bad it is working ok, but the issue is

--sync-usage-file

is destructive when using with wildcards (both for

for_each

and

count

)

9:36 AM

it deletes all the wildcard

aws_lambda_function.hello_world[*]

and replaces them with individual

aws_lambda_function.hello_world["hi"]

and

"hello"

with default value

hmmm that's an interesting issue. I guess in that case it should recognise the wildcards and not overwrite them.

We should also consider this behavior (having both wildcard and resource) in

--sync-usage-file

logic

10:57 AM

submitted an issue for

--sync-usage-file

flag behavior: https://github.com/infracost/infracost/issues/875 submitted a PR for clarifying wildcard usage with for_each: https://github.com/infracost/docs/pull/81
