Terraform Openstack Instances

This project aims to create a module to deploy instance(s) on openstack provider.

Note: This module requires Terraform version 1.5.0 or higher and OpenStack provider version 3.2.0 or higher.

Terraform Registry

module "instance-module" {
  source  = "atlet99/instance-module/openstack"
  version = "1.0.3"
  # insert the 4 required variables here
}

Usage examples

module "test_instance_simple" {
