terraform OpenStack 리소스 생성 샘플

1. Flavor 생성

resource "openstack_compute_flavor_v2" "C2M2D20" {
  name      = "C2M2D20"
  ram       = "2048"
  vcpus     = "2"
  disk      = "20"
  is_public = "true"
}

 

2. Image 생성

resource "openstack_images_image_v2" "rhel7_6" {
  name             = "rhel7.6"
  local_file_path  = "/home/test/rhel7.qcow"
  container_format = "bare"
  disk_format      = "qcow2"
  visibility       = "public"


  properties = {
    key = "value"
  }
}

 

3. Network 및 Subnet 생성

resource "openstack_networking_network_v2" "public_net" {
  name           = "public_net"
  admin_state_up = "true"
  shared         = "true"
  external       = "true"
  mtu              = "1500"
  availability_zone_hints = ["OVS"]
  port_security_enabled = "false"


  segments {
    physical_network = "physnet"
    network_type     = "flat"
  }
}




resource "openstack_networking_subnet_v2" "public_subnet" {
  name       = "public_subnet"
  network_id = "${openstack_networking_network_v2.public_net.id}"
  cidr       = "100.100.100.0/24"
  ip_version = 4
}

 

4. keystone 인증

# Configure the OpenStack Provider
provider "openstack" {
  tenant_name = "admin"
  user_name   = "admin"
  password    = "admin"
  auth_url    = "http://10.80.12.14:5000"
  insecure    = "true"
  region      = "regionOne"
}

 

5. variables 정의

# global variables
variable "Instance" {
  default = {
    image_id    = "74dab4a8-852c-4096-afe5-fa7a0edf265b"  # RHEL7_6
  }
}


variable "network" {
  default = {
    id          = "ab5d012c-b1d9-478c-8279-6acfff9a4c2c"
    subnet_id   = "8f03f155-30bb-4279-9558-dcba8a974c76"
  }
}

 

6. VM 생성

resource "openstack_compute_instance_v2" "testvm2" {
  name              = "testvm2"
  image_id          = "${openstack_images_image_v2.rhel7_6.id}"
  flavor_id         = "${openstack_compute_flavor_v2.C2M2D20.id}"
  availability_zone = "OVS"


  network {
    name = "public_net"
  }
}
