This function is useful when you want to aggregate configurations from multiple sources. It is mostly used to create flexible and modular configurations. variable "base_config" {.From your data structure above, it seems like you need to take nested values from the object rather than just “turn the object into a string”. In that for expression you wrote, v is the current object from the list, and so e.g. v.name would refer to …Related Functions. join performs the opposite operation: producing a string joining together a list of strings with a given separator. The split function produces a list by dividing a given string at all occurrences of a given separator.I want to concatenate the values of a list of maps that share the same key. I have a list of maps that looks like this: tags = [ { key = "env" value = "dev" }, { ...Your arguments to concat have a typo, you need to supply multiple lists which are to be concatenated, while you have supplied a single list (this however would probably be a valid argument to flatten).The index function finds the element index for a given value in a list.list: This parameter represents the list of strings that you want to concatenate into a single string. The list parameter should be an expression that evaluates to a list, typically a list of strings, but it can also contain other types that Terraform can implicitly convert to strings.Terraform concatenate sublists. 0.

The resource for_each and dynamic block language features both require a collection value that has one element for each repetition. Sometimes your input data structure isn't naturally in a suitable shape for use in a for_each argument, and flatten can be a useful helper function when reducing a nested ...As @eedwardsdisco points out the issue is that there is no syntax for list literals in HIL. We may change this in 0.7 to add support, but for now you need to use concat, or a resource field which results in a list as input to concat. Please feel free to reopen this if you have further questions.Related Functions. contains tests whether a given list or set contains a given element value. setintersection computes the intersection of multiple sets. setproduct computes the Cartesian product of multiple sets. The setunion function takes multiple sets and produces a single set containing the elements from all of the given sets.Understanding Lists in Terraform. Briefly, a list is an ordered collection of values where each value is of the same type. before diving into manipulating lists, ensure that you have Terraform installed and are familiar with basic concepts like variables and resources.compact Function. compact takes a list of strings and returns a new list with any null or empty string elements removed.Note: New versions of Terraform will be placed under the BUSL license, but everything created before version 1.5.x stays open-source.

This works without anyresource_id = each.key. resource_target = each.value.target. } This uses a for expression to project the list of objects into a map of objects, using the id attribute as the key for each element.
