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.

In each example, it is assumed that authentication to the relevant cloud provider has already been implemented.

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.

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. The above example showed a for expression with only a single temporary symbol s , but a for expression can optionally declare a pair of temporary symbols in order to use the key or index of each item too:. For a map or object type, like above, the k symbol refers to the key or attribute name of the current element. You can also use the two-symbol form with lists and tuples, in which case the additional symbol is the index of each element starting from zero, which conventionally has the symbol name i or idx unless it's helpful to choose a more specific name:. The index or key symbol is always optional.

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. This is due to the unique index object assigned. For example, when using count with a list variable, an attempt to change a resource that has been assigned an earlier index in the sequence could have unintended consequences on subsequent resources.

To clarify, here is the new question. To review, open the file in an editor that reveals hidden Unicode characters. Terraform is a powerful infrastructure-as-code tool that allows you to define and provision infrastructure resources. Hi jefferson-monteiro-iupp , would you please try asking your question in the community forum? Using the count meta-argument The count meta-argument is the simplest of the looping constructs within Terraform. 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. I can't imagine to use No one here is dumb, even me and I was feeling pretty dumb earlier, which is why I switched to my personal account to own up to the mistake. 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. 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.

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. Since this can be a string, we can assign the name of each resource to be the value in the variable by using each. The screenshot below shows the four Ubuntu instances created. Although the answer solved the problem at the time, I've now adjusted the data set meaning I need to traverse three tiers. To achieve your goal of converting a list of strings into a map of objects in Terraform, follow these steps:. When dealing with virtual compute instances, this lack of transparency could have disastrous implications. So any elements of var. Can be combined with Terraform operators and functions such as if, join, replace, or lower and upper. Still, a good question for the community forum! Now, use a for loop to transform this list into a map of objects. The count. Instantly share code, notes, and snippets.
