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:.

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. Extra characters after the end of the 'for' expression. Error: Missing attribute value. Key expression is required when building an object. Assuming this is doable and I am just too dumb to figure it out very likely , some documentation would be really helpful. The text was updated successfully, but these errors were encountered:. Hi sleterrier , I refuse to believe that you are dumb - you're using terraform, after all! Terraform 0. 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.

Hopescope, you have successfully converted the list of property names into a map of objects with the desired structure. Azure storage accounts contain all data objects in an Azure subscription, such as blobs, file shares, queues, tables, and disks.

Terraform for loop is a very powerful tool that helps you write flexible and scalable Terraform code. It is especially useful when it comes to map transformation. It helps when you need more flexibility in your infrastructure code to write DRY code that scales. With a for loop, you can iterate through the keys and values of a map, applying custom logic to each element. This logic can involve filtering out certain elements, generating new keys or values, and creating entirely new maps based on the original data. This can be useful for creating variations of configurations. Map transformation using for loops enhances code readability, maintainability, and flexibility in your Terraform configurations. These examples should give you a solid foundation for understanding how to perform various map transformations using for loops in Terraform.

I will have some nested folders with more than two levels like below:. Rethinking Cloud Value The new cloud imperative is ensuring value guides every decision. Terraform is a powerful infrastructure-as-code tool that allows you to define and provision infrastructure resources. Image shows the unintended deletion of resource number2. The image shows that the beta Google Cloud Compute instance will be destroyed deleted. A small variation on this would be to use a local list variable and use this to determine the number of deployed resources. This helps keep the issue conversation on the topic of the original issue. Deploying simple, identical resources that are unlikely to change.

This is because the length of the variable the number of items contained within it has been reduced to only three, so the fourth item is removed and not the second. Hi mildwonkey , thanks for taking a stab at this, much appreciated! The image shows that the machine type will be changed. No worries! What you might understandably expect, is for the second instance named my-machine1 i. This time, the name of the instance is set to the values in the variable i. What is the correct way to do this iteration without having to write the entire directory? The my-machine1 instance has not been deleted, but my-machine3 has. It is a nested loop! Image shows the unintended deletion of resource number2. But truly transforming cloud financial management will require a quantum leap forward The image shows the creation of the new fourth S3 bucket in the AWS console.
