Variables

Terraform uses variables to make configurations more flexible and reusable. Variables can be declared in .tf files and assigned values through various methods, including default values, command-line flags, environment variables, or separate .tfvars files. They support multiple data types such as string, number, bool, list, and map. Variables can be referenced throughout the configuration using the var prefix. This system enables infrastructure as code to be more dynamic and adaptable to different environments or use cases.
