dynamic { }

Example[edit]

 dynamic "parameter" {
   for_each = var.parameters
   content {
     name         = parameter.value.name
     value        = parameter.value.value
     apply_method = lookup(parameter.value, "apply_method", null)
   }
 }


locals {
  dynamic     = "key_b"
  my_map_json = jsonencode({
    key_a           = "something"
    (local.dynamic) = "else"
  })
  # ...
}
