Terraform create map with for loop

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.

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.

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:.

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. This for expression iterates over each element of var. It then builds a new tuple value with all of the results of executing that expression in the same order. A for expression's input given after the in keyword can be a list, a set, a tuple, a map, or an object.

I am still wondering how the association-list code you pasted above does not constitute a nested for loop though. Running terraform plan shows that this will cause Terraform to amend the machine type of the beta instance to e2-medium. In each example, it is assumed that authentication to the relevant cloud provider has already been implemented. The text was updated successfully, but these errors were encountered:. Reference There is however one last thing I am not clear about, based on We invite you to learn more about CloudBolt's new vision and join us on our mission to ensure that ROI drives every cloud strategy. To clarify, here is the new question. Skip to content. I will have some nested folders with more than two levels like below: Bucket-1 provider-1 batch-process people cart online-process log order Since this can be a string, we can assign the name of each resource to be the value in the variable by using each.

Now, use a for loop to transform this list into a map of objects. A basic example often cited is to transform a list of variables into uppercase when combined with the upper function. However, the output of terraform plan shows the following:. Any updates on this? Extra characters after the end of the 'for' expression. Terraform is a declarative language, which means that the desired state is described in manifest files and modules. Hi mildwonkey , thanks for taking a stab at this, much appreciated!

Let me spend a little longer thinking about this - I'm still fairly positive that we can't do precisely what you are requesting at this time, but I might be able to come up with a workaround, or at least a better-thought-out feature request : Sorry again, cheers and thanks for the update.
