tfvar-to-tfevar

tfvar-to-tfevar is a way to export Terraform's variable definitions to Terraform Enteprise or Terraform Cloud variables

It is heavily based on the awesome original work in tfvar

For Terraform configuration that has input variables declared, e.g.,

variable "image_id" {
  type = string
}

variable "availability_zone_names" {
  type    = list(string)
  default = ["us-west-1a"]
}

variable "docker_ports" {
  type = list(object({
    internal = number
    external = number
    protocol = string
  }))
  default = [
    {
      internal = 8300
      external = 8300
      protocol = "tcp"
    }
  ]
}

It will create valid Terraform code for the TFE Provider as individual tfe_variable resources.

$ tfvar-to-tfevar .
resource "tfe_variable" "availability_zone_names" {
  key          = "availability_zone_names"
  value        = <<EOT
availability_zone_names = ["us-west-1a"]
EOT
  category     = "terraform"
  hcl          = true
  workspace_id = data.tfe_workspace.example_workspace.id
  description  = ""
}

resource "tfe_variable" "docker_ports" {
  key          = "docker_ports"
  value        = <<EOT
docker_ports = [{
  external = 8300
  internal = 8300
  protocol = "tcp"
}]
EOT
  category     = "terraform"
  hcl          = true
  workspace_id = data.tfe_workspace.example_workspace.id
  description  = ""
}

resource "tfe_variable" "image_id" {
  key          = "image_id"
  value        = <<EOT
image_id = null
EOT
  category     = "terraform"
  hcl          = true
  workspace_id = data.tfe_workspace.example_workspace.id
  description  = ""
}

If you then add a valid tfvars file, it'll read that as well and set values for the inputs:

$ tfvar-to-tfevar . --var-file='test.tfvars'
resource "tfe_variable" "availability_zone_names" {
  key          = "availability_zone_names"
  value        = <<EOT
availability_zone_names = ["us-west-1a"]
EOT
  category     = "terraform"
  hcl          = true
  workspace_id = data.tfe_workspace.example_workspace.id
  description  = ""
}

resource "tfe_variable" "docker_ports" {
  key          = "docker_ports"
  value        = <<EOT
docker_ports = [{
  external = 8300
  internal = 8300
  protocol = "tcp"
}]
EOT
  category     = "terraform"
  hcl          = true
  workspace_id = data.tfe_workspace.example_workspace.id
  description  = ""
}

resource "tfe_variable" "image_id" {
  key          = "image_id"
  value        = "xyz"
  category     = "terraform"
  workspace_id = data.tfe_workspace.example_workspace.id
  description  = ""
