This article discusses the element function in Terraform, which is used to select an element from a collection of values such as lists or tuples. The element function takes two arguments: the collection and the index of the desired element. It can be particularly useful when working with large numbers of elements or when you want to cycle through a list or select an item based on a variable index. The article also provides examples of how to use the element function in different scenarios, such as evenly distributing subnets across availability zones in AWS. Additionally, it highlights some key features and benefits of using Spacelift for managing Terraform workflows, including support for multiple IaC tools, policy enforcement, and self-service infrastructure provisioning.
