What type of values can variables in Terraform hold?

Variables in Terraform are versatile and can hold a wide range of value types, which is crucial for creating flexible and reusable code. Specifically, variables can hold strings, numbers, lists, maps, and booleans. This variety allows Terraform configurations to adapt to different situations and architectures.

• Strings are used for textual data, such as resource names or configuration settings.

• Numbers can represent integer and floating-point values, which are essential for specifying resource sizes or counts.

• Lists are ordered collections of values that can be of any type, enabling complex parameterizations where multiple values are handled together.

• Maps are collections of key-value pairs, allowing for structured data that is easy to manage and reference throughout the configuration.

• Booleans (true or false values) are critical for conditional logic within infrastructure code.

Having the capability to define variables in these diverse formats makes Terraform a powerful tool for infrastructure as code, ensuring configurations are not only dynamic but also maintainable. This flexibility is essential for accommodating various resource configurations and environments.
