====== Terraform Map statement ======

<code>
$ more main.tf
variable "owner" {
  description = "Hat owner"
  type        = string
}


variable "var_map" {
  type = map(string)
  default = {
    tom  = "Trilby"
    bertie  = "Bowler"
    harry  = "Homberg"
  }
}


output "owner" {
  value = var.owner
}
output "hatvalue" {
  value = "${lookup(var.var_map, var.owner)}"
}
output "hatvalue1" {
  value = var.var_map[var.owner]
}

</code>



<code bash>
$ terraform apply
var.owner
  Hat owner

  Enter a value: bertie


Changes to Outputs:
  ~ hatvalue = " wears  Homberg" -> " wears  Bowler"
  ~ owner    = "harry" -> "bertie"

You can apply this plan to save these new output values to the Terraform state, without changing any real infrastructure.

====== Map object ======


<code>
variable "map_object" {
  type = map(object({
    var1 = string
    var2 = string
    var3 = bool
    }))

  default = {
    "east-1" = {
      var1 = "variable1east - string"
      var2 = "variable2east - string"
      var3 = true
    }
    "west-1" = {
      var1 = "variable1west - string"
      var2 = "variable2west - string"
      var3 = true
    }

  }
}


output "choice_obj" {
  value = var.map_object["east-1"]
}

output "Choice_var1" {
  value = var.map_object["east-1"].var2
}
</code>


<code bash>
$ terraform apply

Changes to Outputs:
  + Choice_var1 = "variable2west - string"
  + choice_obj  = {
      + var1 = "variable1west - string"
      + var2 = "variable2west - string"
      + var3 = true
