If you tag them from an external source and not on the resource, be aware that running the resource Terraform will delete the externally added tags, unless you add an ignore_changes for tags to each resource- ultimately defeating the point.I'm not fully sure I understand what your goal is, but it seems like it involves reorganizing the elements to group them by their indices. Assuming that all of your lists will always be the same length, you could achieve that with a for expression, which is comparable to a list or map comprehension in Python.The syntax of Terraform configurations is custom. It is meant to strike a balance between human readable and editable as well as being machine-friendly. For machine-friendliness, Terraform can also read JSON configurations. For general Terraform configurations, however, we recommend using the Terraform syntax.Oct 8, 2020 · 1 Answer. Sorted by: 1. The important thing here is that, as you've noticed, Terraform's map type is an unordered map which identifies elements only by their keys, not by permission. Therefore if you have a situation where you need to preserve the order of a sequence then a map is not a suitable data structure to use. Sep 26, 2020 · At the moment I have a series of map outputs for this resource group but each consists of only a single key-value pair. I would like my terraform output to include a list or map of maps or objects with all of the attributes grouped by resource instance.

Both keyslist and valueslist must be of the same length. keyslist must be a list of strings, while valueslist can be a list of any type. Each pair of elements with the same index from the two lists will be used as ... setproduct Function. The setproduct function finds all of the possible combinations of elements from all of the given sets by computing the Cartesian product. setproduct (sets...) This function is particularly useful for finding the exhaustive set of all combinations of members of multiple sets, such as per-application-per-environment resources. 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 flatten can be a useful helper function when reducing a nested ... 1 Answer. Your new output key, the one where zipmap is used, is going to produce a map with keys of alias name, and the corresponding values of keys arn. This will be something as follows: output "key" { description = "The 'Amazon Resource Name (ARN)' of 'KMS' key (s)" value = { alias_name1 = key_arn1 alias_name2 = key_arn2 …The Terraform language includes a number of built-in functions that you can call from within expressions to transform and combine values. The general syntax for function calls is a function name followed by comma-separated arguments in parentheses: max ( 5, 12, 9) For more details on syntax, see Function Calls in the Expressions section. In Terraform, the template_file data source is the preferred method of, for example, injecting variable data into a templated-file like a script or configuration file. In my case, I make heavy use of template_file as part of the spin-up routine for servers on Equinix Metal which uses cloud-init to run a script on first boot to configure the host..

By understanding these data types and how to use them together, you can write more efficient and readable Terraform configurations.
1. You can't dynamically create fully independent variables. Instead you can create a map in few ways. One way would be with the help of transpose and zipmap: output "test1" { value = transpose (zipmap (keys (local.data), values (local.data) [*].user_assigned)) } Resulting in: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. …
