I will be providing values with terragrunt. The variable, push_subscriptions, is a list of maps and I want to modify the values of the map. For example, append a prefix to the push subscription name in place like so (within the main.tf):Another option is to use the terraform-null-label module. It supports passing a variable called tags as a standard Terraform map. The module then emits an output called tags_as_list_of_maps which contains the tags in the format you want. But an even better reason to use this module is to generate a consistent set of resource names that follow a fixed convention.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 ...At first we group by hub each item from accounts and then we loop through this map of groups and build a new list with the desired format. The output of the code above will look something like this: account_groups = [. {. "hub" = "54326543266". "ou_name" = "test1". "spokes" = [.Terraform Map is a key concept in infrastructure as code, offering a flexible way to manage configurations. It allows you to efficiently define and manipulate resources with key-value pairs. Understanding its functionality and applications can significantly enhance your infrastructure management strategies. Terraform Map.

kubernetes_config_map. The resource provides mechanisms to inject containers with configuration data while keeping containers agnostic of Kubernetes. Config Map can be used to store fine-grained information like individual properties or coarse-grained information like entire config files or JSON blobs.Terraform, a popular open-source tool created by HashiCorp, enables users to define and provision infrastructure using a high-level configuration language. Lists, or arrays, are fundamental data types in Terraform that store ordered sequences of values. Concatenating lists refers to the process of merging two or more lists into a single list.

In other non-JSON situations, when the result is a simple list of strings, the join function can be useful to just concatenate all of the strings together with a fixed delimiter. Any of Terraform's functions that produce a single string as a result is a candidate here. The ones under "String Functions" and "Encoding Functions" are the most ...

In some cases you can just set tags = ${local.common_tags}, or if you need to include some resource-specific tags in addition to the common ones you can use merge as shown. @nikobelia You can define locals at the top of the project. Then you can define only one variable in each sub directories/modules for tagging.Pass a set value to tolist to convert it to a list. Since set elements are not ordered, the resulting list will have an undefined order that will be consistent within a particular run of Terraform. So it is meant to convert a set (with no indices) to a list but it cannot convert a string to a list.I followed this link to generate code above Terraform: how to iterate over key-value pairs of map input via json file Everything is good except for the index key.
