See examples, answers, and references from the Terraform community.NOTE: this method would be considered garbage in any programming language because it's time and resource wasting but this is the only way I could find in Terraform as it's still too limited language. I believe such a thing will become much easier in the near future as Terraform is stll growing and evolving.Although in principle template_file can be used with an inline template string, we don't recommend this approach because it requires awkward escaping. Instead, just use template syntax directly in the configuration.

Here’s how you can use it: my_list = ["foo", "bar", "xid", "b59"] my_str = join(", ", my_list)Syntax. The syntax of a conditional expression is as follows: If condition is true then the result is true_val. If condition is false then the result is false_val. A common use of conditional expressions is to define defaults to replace invalid values: If var.a is an empty string then the result is "default-a", but otherwise it is the actual ...I am trying to use join to run multiple user_data files where var.user_data_file would be common within the module and var.user_data would be passed where the module is called. This works without anyIn a simple scenario, you might have a variable that stores an environment name, and you wish to convert this to uppercase to use as part of a resource identifier. type = string default = "development" } This same approach applies for converting to lowercase, which might be useful for creating DNS records, for example.Passing a null value as a module input argument will override any default value. Setting nullable to false ensures that the variable value will never be null within the module. If nullable is false and the variable has a default value, then Terraform uses the default when a module input argument is null. Clearly, this is NOT happening for me ….Since the JSON format cannot fully represent all of the Terraform language types, passing the jsonencode result to jsondecode will not produce an identical value, but the automatic type conversion rules mean that this is rarely a problem in practice..

Create a Terraform file ( main.tf) and input the following: locals { . list_one = ["A", "B", "C"] . list_two = ["D", "E", "F"] . combined_list = concat(locals.list_one, locals.list_two) } . output "combined_list" { value = locals.combined_list. }Use-cases. I have a dynamically-generated map of maps (or list of maps), and I'd like to merge them all down to a single map, using standard merge(map1, map2, ...) rules. FWIW, using merge() with objects also seems to work, as it's a shallow merge, so I'd like to keep that behavior, too.. I use these for picking up hierarchical variables from my directory …By using for_each, we will cause Terraform to create resource instance addresses like aws_iam_policy.policy["cw"] rather than like aws_iam_policy.policy[1], and so adding and removing elements from the map will cause Terraform to add and remove corresponding instances from the resource, rather than try to update instances in-place to respect ...terraform Concatenate variable and string. 22. concatenate two variables in terraform. 0.

Both valueslist and keyslist must be the same length. The ordering of the values in valueslist is preserved in the result.Local variables are a critical tool to have in your Terraform toolbox and something that you should have a solid grasp on. They can be used to store static pieces of information like a constant in a programming language, or they can be used to mutate data and/or concatenate pieces of data. Both are equally useful.Terraform tfvars files are instrumental in Terraform configurations. They allow you to declare variables that customize your infrastructure setup. Typically named terraform.tfvars or *.auto.tfvars, these files use a simple key-value format for variable definition. For example: region = "us-west-1".The list function is no longer available. Prior to Terraform v0.12 it was the only available syntax for writing a literal list inside an expression, but Terraform v0.12 introduced a new first-class syntax.
