As the comments mention you can't interpolate variables like that in Terraform or do things like default a variable to another variable you could achieve your stated aim using data sources. In the example case you could do something like the following: variable "env" {. default = "production". }Conditional + concat = new resource. It's very difficult to phrase the question properly, but hopefully the post will explain things a bit better. For some reason, Terraform always thinks it has to recreate a resource, because I'm passing in a value that is calculated at runtime.

This function is particularly useful when dealing with multiple sets of similar data, such as tags or network configurations. It ensures a more streamlined and efficient approach to managing resources in Terraform.Terraform will construct the valid JSON syntax itself as part of evaluating the jsonencode function call. Your new requirement is to omit Condition entirely in certain cases. To describe that requirement as a Terraform expression requires merging the object which describes the parts that are always present ( Effect , Action , and Resource ...To use, simply paste the following into a file named oci.tf in an empty directory and then run terraform init, followed by terraform plan in the same directory.

If more than one given map or object defines the same key or attribute, then the one that is later in the argument sequence takes precedence. If the argument types do not match, the ...So far this is reasonable: the two values have distinct element types because their structure was different. However, things get confusing when we pass these results into concat, because it has a special case where if all of its arguments are lists and the list element types all have a common base type then it will produce a list of that common base type as the result.I was trying to concatenate two list of maps using count.index. locals{final_tags = concat ([var.vmTags], [(element([var.extraTags], count.index)] ) } Do you think it could have also worked? Reply ... compare terraform code that uses very little logic, with the same code in something like CDK or pulumi, and the difference is staggering: it is ...A stack represents a collection of infrastructure that CDK for Terraform (CDKTF) synthesizes as a dedicated Terraform configuration.

The join function produces a string by concatenating the elements of a list with a given delimiter.
Because for expressions can convert from unordered types (maps, objects, sets) to ordered types (lists, tuples), Terraform must choose an implied ordering for the elements of an unordered collection. For maps and objects, Terraform sorts the elements by key or attribute name, using lexical sorting. For sets of strings, Terraform sorts the ...The slice function extracts some consecutive elements from within a list.
Terraform in practice. The best way to underst Terraform supports uppercase letters and dashes in identifiers only to make it more convenient to write names that will be sent to remote systems that may have different conventions. Your input variable would ideally be named iam_policy_users_map instead, and likewise your output value be association_map.Terraform’s concat function is versatile but expects that all lists being concatenated are of the same type or structure. Mixing different types (e.g., string and number) in a single list can lead to unexpected behavior or errors. If you encounter such a scenario, it’s advisable to homogenize your lists before concatenation. ... Prior to Terraform v0.12 it was the only avaiAWS published IAM Best Practices and this References to Named Values. Hands-on: Try the Create Dynamic Expressions tutorial.
