» list Function

The list function is no longer available. Prior to Terraform v0.12 it was the only available syntax for writing a literal list inside an expression, but Terraform v0.12 introduced a new first-class syntax.

To update an expression like list(a, b, c), write the following instead:

tolist([a, b, c])

The [ ... ] brackets construct a tuple value, and then the tolist function then converts it to a list. For more information on the value types in the Terraform language, see Type Constraints.

  • concat produces a new list by concatenating together the elements from other lists.
  • tolist converts a set or tuple value to a list.
