OpenTofu is an open-source version of Terraform that will expand on Terraform’s existing concepts and offerings. It is a viable alternative to HashiCorp’s Terraform, being forked from Terraform version 1.5.6.Terraform's concat function is a handy tool for combining lists or sets of strings, playing a crucial role in infrastructure as code. It allows for more efficient and flexible management of resources in your configurations. Understanding concat can significantly streamline your Terraform scripts, making them more readable and maintainable.Feb 13, 2021 · Running Terraform v0.11.3 and I am trying to merge two maps into a single map using the merge() ... merge list of maps and concatenate their value from duplicate keys. 0.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 …944 6 21 54. 1. Unfortunately most languages' map/hash/dict map function will merge one level deep, and not recursively. You would have to code a custom lambda for this.

This helps our maintainers find and focus on the active issues. If you have found a problem that seems similar to this, please open a new issue and complete the issue template so we can capture all the details necessary to investigate further.Hi @amanohar,. The == operator can only return true when the two operands have identical types, and the type of [] alone (without any further type conversions) is an empty tuple rather than a list of strings and so I expect that comparison is always returning false.. If your goal is to use different behavior when the list is empty, test the length of …Using the merge () function. To merge two maps in Terraform, we primarily use the merge function. The merge function takes two or more maps as inputs and produces a single map that contains a union of the keys and values from all the input maps. When keys overlap, the value from the map that is later in the argument list will take …split performs the opposite operation: producing a list by separating a single string using a given delimiter. The join function produces a string by concatenating the elements of a list with a given delimiter.Aug 14, 2023 · concat(keycloak_user.user, var.keycloak_user_ext) Has two problems: keycloak_user.user is (essentially) a map of 4 keycloak_user resources (since you defined it with the for_each); and; var.keycloak_user_ext is just a simple string (as far as Terraform knows).The additional brackets turn the list result of concat into a list of lists, which is not what you want here.

Expanding upon the example in your question: Expanding upon the example in your question: variable "foo" { type = "list" default = [ 1,2,3 ] } # assume a value of 4 of type number is the additional value to be appended resource "bar_type" "bar" { bar_field = "${concat(var.foo, [4])}" }Since Terraform’s concept of a set requires all of the elements to be of the same type, mixed-typed elements will be converted to the most general type (for example, if strings and numbers are supplied in the list together).Also note that sets cannot contain duplicate values, and any duplicate values supplied are coalesced. Sets are also unordered, so …tostring Function. tostring converts its argument to a string value. Explicit type conversions are rarely necessary in Terraform because it will convert types automatically where required. Use the explicit type conversion functions only to normalize types returned in module outputs. Only the primitive types (string, number, and bool) and null ...split performs the opposite operation: producing a list by separating a single string using a given delimiter. The join function produces a string by concatenating the elements of a list with a given delimiter.The Terraform language uses the following types for its values: string: a sequence of Unicode characters representing some text, like "hello". number: a numeric value. The number type can represent both whole numbers like 15 and fractional values like 6.283185. bool: a boolean value, either true or false. bool values can be used in conditional ...You can use the concat function for this. Expanding upon the example in your question: Expanding upon the example in your question: variable "foo" { type = "list" default = [ 1,2,3 ] } # assume a value of 4 of type number is the additional value to be appended resource "bar_type" "bar" { bar_field = "${concat(var.foo, [4])}" }Sep 20, 2021 · Terraform: how to set the value of a string on multiple lines but the result is one line 3 Is there a way to convert a text list with /n (new line) to a string list for Terraform?To perform the coalesce operation with a list of strings, use the ... symbol to expand the list as arguments: > coalesce(["", "b"]...) b Terraform attempts to select a result type that all of the arguments can convert to, so mixing argument types may produce surprising results due to Terraform's automatic type conversion rules:Indirectly-nested lists, such as those in maps, are not flattened.. Flattening nested structures for for_each. 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 …distinct Function. distinct takes a list and returns a new list with any duplicate elements removed. The first occurrence of each value is retained and the relative ordering of these elements is preserved.The slice function extracts some consecutive elements from within a list.regex Function. regex applies a regular expression to a string and returns the matching substrings. The return type of regex depends on the capture groups, if any, in the pattern: If the pattern has no capture groups at all, the result is a single string covering the substring matched by the pattern as a whole.30 Jun 2021 ... I have two maps in the following format: nodes = { node1 = { item0 = string item1 = list item2 = list item3 = list } node2 = { .A list of benchmark fractions include 1/4, 1/3, 1/2, 2/3 and 3/4. Benchmark fractions are common fractions that are used for comparison to other numbers. For example, the benchmark...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 ...One of the simplest ways to iterate over a map in Terraform is using the count parameter within a resource declaration. This method is especially useful for creating multiple instances of a resource. count = length(var.instance_details) ami = "ami-123456". instance_type = var.instance_details[keys(var.instance_details)[count.index]].size.Dec 24, 2020 · To be able to conditionally append objects (or strings) to a list in terraform we must put it in another way: How do we dynamically generate a list of objects?

In V0.11 I use this: ${var.name}-STRING-${var.name2}, in V0.12 can I use this: var.name"-STRING-"var.name2 or must I use another ways to concatenate variables and strings?The Terraform language has a built-in operator [*], known as the splat operator, and one of its functions is to translate a primitive value that might be null into a list of either zero or one elements: variable "ec2_instance_type" { description = "The type of instance to create. If set to null, no instance will be created."distinct Function. distinct takes a list and returns a new list with any duplicate elements removed. The first occurrence of each value is retained and the relative ordering of these elements is preserved.I would say rather concatenating at resource level use the locals first define a variable in locals and then you can utilize it at resource level.
