OpenStack Provider

The OpenStack provider is used to interact with the many resources supported by OpenStack. The provider needs to be configured with the proper credentials before it can be used.

Use the navigation to the left to read about the available resources.

Example Usage

# Configure the OpenStack Provider
provider "openstack" {
    user_name  = "admin"
    tenant_name = "admin"
    password  = "pwd"
    auth_url  = "http://myauthurl:5000/v2.0"

# Create a web server
resource "openstack_compute_instance_v2" "test-server" {

Configuration Reference

The following arguments are supported:

  • auth_url - (Required) If omitted, the OS_AUTH_URL environment variable is used.

  • user_name - (Optional; Required for Identity V2) If omitted, the OS_USERNAME environment variable is used.

  • user_id - (Optional)

  • password - (Optional; Required if not using api_key) If omitted, the OS_PASSWORD environment variable is used.

  • token - (Optional; Required if not using user_name and password) A token is an expiring, temporary means of access issued via the Keystone service. By specifying a token, you do not have to specify a username/password combination, since the token was already created by a username/password out of band of Terraform. If omitted, the OS_AUTH_TOKEN environment variable is used.

  • api_key - (Optional; Required if not using password) An API Key is issued by a cloud provider as alternative password. Unless your cloud provider has documentation referencing an API Key, you can safely ignore this argument. If omitted, the OS_API_KEY environment variable is used.

  • domain_id - (Optional) If omitted, the OS_DOMAIN_ID environment variable is used.

  • domain_name - (Optional) If omitted, the OS_DOMAIN_NAME environment variable is used.

  • tenant_id - (Optional)

  • tenant_name - (Optional) If omitted, the OS_TENANT_NAME environment variable is used.

  • insecure - (Optional) Explicitly allow the provider to perform "insecure" SSL requests. If omitted, default value is false

  • cacert_file - (Optional) Specify a custom CA certificate when communicating over SSL. If omitted, the OS_CACERT environment variable is used.

  • cert - (Optional) Specify client certificate file for SSL client authentication. If omitted the OS_CERT environment variable is used.

  • key - (Optional) Specify client private key file for SSL client authentication. If omitted the OS_KEY environment variable is used.

  • endpoint_type - (Optional) Specify which type of endpoint to use from the service catalog. It can be set using the OS_ENDPOINT_TYPE environment variable. If not set, public endpoints is used.

Rackspace Compatibility

Using this OpenStack provider with Rackspace is not supported and not guaranteed to work; however, users have reported success with the following notes in mind:

  • Interacting with instances has been seen to work. Interacting with all other resources is either untested or known to not work.

  • Use your password instead of your Rackspace API KEY.

  • Explicitly define the public and private networks in your instances as shown below:

resource "openstack_compute_instance_v2" "my_instance" {
  name = "my_instance"
  region = "DFW"
  image_id = "fabe045f-43f8-4991-9e6c-5cabd617538c"
  flavor_id = "general1-4"
  key_pair = "provisioning_key"

  network {
    uuid = "00000000-0000-0000-0000-000000000000"
    name = "public"

  network {
    uuid = "11111111-1111-1111-1111-111111111111"
    name = "private"

If you try using this provider with Rackspace and run into bugs, you are welcomed to open a bug report / issue on Github, but please keep in mind that this is unsupported and the reported bug may not be able to be fixed.

If you have successfully used this provider with Rackspace and can add any additional comments, please let us know.

Testing and Development

In order to run the Acceptance Tests for development, the following environment variables must also be set:

  • OS_REGION_NAME - The region in which to create the server instance.

  • OS_IMAGE_ID or OS_IMAGE_NAME - a UUID or name of an existing image in Glance.

  • OS_FLAVOR_ID or OS_FLAVOR_NAME - an ID or name of an existing flavor.

  • OS_POOL_NAME - The name of a Floating IP pool.

  • OS_NETWORK_ID - The UUID of a network in your test environment.

  • OS_EXTGW_ID - The UUID of the external gateway.

To make development easier, the builtin/providers/openstack/devstack/ script will assist in installing and configuring a standardized DevStack environment along with Golang, Terraform, and all development dependencies. It will also set the required environment variables in the devstack/openrc file.

Do not run the script on your workstation or any type of production server. Instead, run the script within a disposable virtual machine. Here's an example of a Terraform configuration that will create an OpenStack instance and then install and configure DevStack inside.
