Write .tf file

admin_pass를 지정했으나 ubuntu 2004에서는 반영되지 않았음.

root@yjwang0-stack-11:~/terraform# cat test.tf 
terraform {
required_version = ">= 0.14.0"
  required_providers {
    openstack = {
      source  = "terraform-provider-openstack/openstack"
      version = "~> 1.35.0"
    }
  }
}

provider "openstack" {
  user_name   = "admin"
  tenant_name = "admin"
  password    = "testtest"
  auth_url    = "http://10.99.99.190:35357/v3"
  region      = "RegionOne"
