map Function

-> Note: This page is about Terraform 0.12 and later. For Terraform 0.11 and earlier, see 0.11 Configuration Language: Interpolation Syntax.

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

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

tomap({
  a = "b"
  c = "d"
})

The { ... } braces construct an object value, and then the tomap function then converts it to a map. For more information on the value types in the Terraform language, see Type Constraints.
