Write Ansible inventory with TF template plugin

Write Ansible inventory with TF inventory plugin

It would be nice if this worked but it is barely usable. If you want to ry then install the terraform-inventory plugin. It is binary that should be somewhere in your path.

terraform {
  backend "local" {
    path = "terraform.tfstate"
  }
}

resource "null_resource" "ansible_inventory" {
  provisioner "local-exec" {
    command = "terraform-inventory --list ./ > inventory.json"
  }
}

Remove something from state

terraform state rm hcloud_floating_ip.dezemagweg`

Import a floating IP address

# when using Hetzner get the id:
hcloud floating-ip list

# us the ID to import
terraform import hcloud_floating_ip.doedezemaar 123456

Use a floating IP address

Command for importing the floating IP: terraform import hcloud_floating_ip.dev-feuerfest 101241234

resource "hcloud_floating_ip_assignment" "dev-aike" {
  floating_ip_id = hcloud_floating_ip.dev-aike.id
  server_id      = hcloud_server.master.id
}

resource "hcloud_floating_ip" "dev-aike" {
  type      = "ipv4"
}

Use Gitlab state backend

terraform {
  backend "http" {}
}
