It’s straightforward and the most direct way to approach the problem of duplicates in lists. Steps to Implement:The combination of those using Terraform built-in concat() function, achieves a 2-layer join of the two lists (common|unique rules). So we wanted to give it a try: locals { rate_limits = concat(var.common_rate_limits, var.unique_rate_limits) } There is however a drawback: .tfvars files can only contain static values.The result of an expression is a value.All values have a type, which dictates where that value can be used and what transformations can be applied to it.. Types. The Terraform language uses the following types for its values: string: a sequence of Unicode characters representing some text, like "hello".; number: a numeric value.The number type can represent both whole numbers like 15 and ...A "character" is a grapheme cluster, as defined by Unicode Standard Annex #29.Note that remote APIs may have a different definition of "character" for the purpose of length limits on string arguments; a Terraform provider is responsible for translating Terraform's string representation into that used by its respective remote system and applying any additional validation rules to it.Neat! That seamlessly combined our two maps. Now, we just need a way to do it automatically. Unfortunately, Terraform does not like referencing variables within other variables, so we're going to utilize a locals map. Within s3-bucket/main.tf, let's create a locals block that allows us to merge our tags, then we'll just reference that ...Security Group Terraform Example — using Tags.
