functions map - Functions - Configuration Language docs-funcs-collection-map The map function constructs a map from some given elements.

map Function

~> This function is deprecated. From Terraform v0.12, the Terraform language has built-in syntax for creating maps using the { and } delimiters. Use the built-in syntax instead. The map function will be removed in a future version of Terraform.

map takes an even number of arguments and returns a map whose elements are constructed from consecutive pairs of arguments.

Examples

> map("a", "b", "c", "d")
{
  "a" = "b"
  "c" = "d"
]

Do not use the above form in Terraform v0.12 or above. Instead, use the built-in map construction syntax, which achieves the same result:

> {"a" = "b", "c" = "d"}
{
  "a" = "b"
  "c" = "d"
]
  • tomap performs a type conversion to a map type.
