How to Use Terraform Console Command – Examples

Terraform console command

Ever needed a quick and easy way to experiment with Terraform functions and expressions? In this short article, we will explore the terraform console command with some examples of how to use it!

Terraform Console Usage & Examples

Try lower("TEST")

variable "region" {
  type = map(any)
  default = {
    "uk1" = {
      "region" = "uksouth",
    },
    "uk2" = {
      "region" = "ukwest",
    },
    "us" = {
      "region" = "eastus",
    }
    "us2" = {
      "region" = "eastus2",
    }
  }
}

resource "random_password" "password" {
  length           = 16
  special          = true
  override_special = "!#$%&*()-_=+[]{}<>:?"
}

variable "cidr" {
  default = "172.16.0.0/20"
}

With the file in the local working directory, run terrform console. I can interact with the console and experiment with different functions.

var.region

var region terraform

var.region.us2

var.region.us2

var.cidr

cidrnetmask(var.cidr)

cidrhost(var.cidr, 3)

cidrhost

Terraform will only calculate the values of some resources after terraform apply — The console will show you this.

random_password.password

Once you have finished experimenting with different functions and expressions, to exit the console, hit Ctrl-C or Ctrl-D, or type exit.
