Terraform create map with for loop

Terraform is a powerful infrastructure-as-code tool that allows you to define and provision infrastructure resources. In some scenarios, you might need to transform a list of strings into a map of objects for your Terraform configurations, terraform create map with for loop. Imagine you have a list of property names in Terraform, represented as strings, and you need to transform this list into a map of objects. Your initial attempt, using a for loop, might result in a list of map objects, but your goal is to have a map of properties.

Terraform is a popular Infrastructure as Code IaC tool among DevOps teams because it is a cloud-agnostic framework for developing and deploying infrastructure. Terraform is a declarative language, which means that the desired state is described in manifest files and modules. Terraform also allows the use of meta-arguments and expressions, that simplify the deployment of multiple similar resources. Since v0. The count meta-argument is the simplest of the looping constructs within Terraform. By either directly assigning a whole number or using the length function on a list or map variable, Terraform creates this number of resources based on the resource block it is assigned to. An index object is assigned to each resource represented by the number in the sequence of creation and can be used to differentiate them e.

While I found some examples on how to produce a list of maps, I am currently failing at producing a map of maps with a nested for loop. I have only managed to get the following errors depending on the variation:. Error: Invalid 'for' expression.

In previous parts, you learned why we picked Terraform , how to use the basic syntax and features of Terraform , how to manage Terraform state , and how to create reusable infrastructure with Terraform modules. Terraform is a declarative language.

All reactions. The new cloud imperative is ensuring value guides every decision. You might find someone who can come up with a clever way to generate the structure you need in the community forum where there are more people ready to help, but I don't believe there's a direct function that will help here. I managed to create a list with all the S3 directories I would like to have, but I know this is not the most efficient way. In this code, we are iterating through local. I am however still interested in seeing how one could produce a map of, let's say maps in nested for loops? It is possible to create a nested map of maps. Already have an account?
