Terraform Locals

Hello Everyone

Welcome to CloudAffaire and this is Debjeet.

In the last blog post, we have discussed terraform backends.

In this blog post, we will discuss terraform locals.

What is terraform local?

The local block defines one or more local variables within a module. Comparing modules to functions in a traditional programming language, if input variables are analogous to function arguments and outputs values are analogous to function return values, then local values are comparable to a function’s local temporary symbols.

Each locals block can have as many locals as needed, and there can be any number of locals blocks within a module. The names given for the items in the local block must be unique throughout a module. The given value can be any expression that is valid within the current module. The expression of a local value can refer to other locals, but as usual reference cycles are not allowed. That is, a local cannot refer to itself or to a variable that refers (directly or indirectly) back to it.

Next, we are going to explain terraform locals with a demo.
