Question

You are refactoring a Terraform configuration and want to verify how a complex expression using cidrsubnet() and element() will evaluate against your variable values before running a plan. You need an interactive way to test the expression without modifying any resources or state. Which approach lets you evaluate the expression against your current variables and state?

Accepted Answer

Run `terraform console` and type the expression to see its evaluated result

Answer

Add the expression to an output block and run `terraform apply` to view the result

Answer

Run `terraform validate` to check the expression syntax and print the value

Answer

Run `terraform plan -target=expression` to preview only the expression output
