values(mapping) returns a list of all values in mapping, in the same order as the keys returned by keys (sorted lexicographically by key).

Signature

values(mapping map) list

​
Example

Extract all configured service ports from a map and validate that none are in the reserved range before starting the stack: 
variable "ports" {
  description = "Port assignments per service"
  type        = map(number)
  default = {
    api       = 8080
    metrics   = 9090
    dashboard = 3000
  }
}

computed "port_list" {
  description = "All configured ports"
  expression  = values(var.ports)
}

task "check-ports" {
  description = "Print all configured ports"
  commands = [
    "echo 'Services: ${join(", ", keys(var.ports))}'",
    "echo 'Ports: ${join(", ", [for p in computed.port_list : tostring(p)])}'",
  ]
}
computed.port_list becomes [3000, 8080, 9090] (sorted by key: dashboard, api, metrics).

Notes

  • The order of values corresponds to the lexicographic order of their keys, not the order they were declared.
  • values also works on objects. When applied to an object, it returns the attribute values as a tuple ordered by lexicographic key order.
  • To get keys, use keys. To look up a specific value by key, use bracket notation or lookup.
