I have only managed to get the following errors depending on the variation:. Error: Invalid 'for' expression.

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. 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. To achieve your goal of converting a list of strings into a map of objects in Terraform, follow these steps:. Start by initializing your list of properties strings in Terraform. Now, use a for loop to transform this list into a map of objects. In this code, we are iterating through local. Now, you have successfully converted the list of property names into a map of objects with the desired structure. The resulting map of objects can then be used in various ways within your Terraform configurations. For example, you can use it to set resource property configurations or combine it with other variables and Terraform code. This capability is particularly useful when you need to generate configurations dynamically or work with structured data in your Terraform code.

Terraform create map with for loop

A for expression creates a complex type value by transforming another complex type value. Each element in the input value can correspond to either one or zero values in the result, and an arbitrary expression can be used to transform each input element into an output element. For example, if var.

Hi sleterrier , I refuse to believe that you are dumb - you're using terraform, after all! But failed miserably, for obvious reasons now. Performing multiple operations on objects stored in a variable. It might also help to know more details of your use case, so we can see if there's another way to accomplish your goal. This uses the new for expression. Image shows the unintended deletion of resource number2. I promise :. Deploying multiple similar resources, whilst allowing some variations e. I thought nested for loops were already supported given that:. I am however still interested in seeing how one could produce a map of, let's say maps in nested for loops?

The screenshot below shows the four compute instances created using the prefix of my-machine and then a unique number assigned by the count. 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. 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. Dismiss alert. Finally, we can resolve the last limitation we saw using the count argument. Error: Missing attribute value. New issue. To achieve your goal of converting a list of strings into a map of objects in Terraform, follow these steps:.
