Overview
When working with configuration files, we might need to do some computations. Expressions are used to make configuration flexible and they contain four major building blocks, which are:
- Values
- Variables
- Operators
- Functions
There are a lot of use cases for Terraform expressions, such as:
-
When we need to join or concatenate values together, we can use the
concat()function. -
When we need to determine the length of a value, we can use ...
