» 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"
  region      = "RegionOne"

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

» Configuration Reference

The following arguments are supported:

  • auth_url - (Optional; required if cloud is not specified) The Identity authentication URL. If omitted, the OS_AUTH_URL environment variable is used.

  • cloud - (Optional; required if auth_url is not specified) An entry in a clouds.yaml file. See the OpenStack os-client-config documentation for more information about clouds.yaml files. If omitted, the OS_CLOUD environment variable is used.

  • region - (Optional) The region of the OpenStack cloud to use. If omitted, the OS_REGION_NAME environment variable is used. If OS_REGION_NAME is not set, then no region will be used. It should be possible to omit the region in single-region OpenStack environments, but this behavior may vary depending on the OpenStack environment being used.

  • user_name - (Optional) The Username to login with. If omitted, the OS_USERNAME environment variable is used.

  • user_id - (Optional) The User ID to login with. If omitted, the OS_USER_ID environment variable is used.

  • tenant_id - (Optional) The ID of the Tenant (Identity v2) or Project (Identity v3) to login with. If omitted, the OS_TENANT_ID or OS_PROJECT_ID environment variables are used.

  • tenant_name - (Optional) The Name of the Tenant (Identity v2) or Project (Identity v3) to login with. If omitted, the OS_TENANT_NAME or OS_PROJECT_NAME environment variable are used.

  • password - (Optional) The Password to login with. 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_TOKEN or OS_AUTH_TOKEN environment variables are used.

  • user_domain_name - (Optional) The domain name where the user is located. If omitted, the OS_USER_DOMAIN_NAME environment variable is checked.

  • user_domain_id - (Optional) The domain ID where the user is located. If omitted, the OS_USER_DOMAIN_ID environment variable is checked.

  • project_domain_name - (Optional) The domain name where the project is located. If omitted, the OS_PROJECT_DOMAIN_NAME environment variable is checked.

  • project_domain_id - (Optional) The domain ID where the project is located If omitted, the OS_PROJECT_DOMAIN_ID environment variable is checked.

  • domain_id - (Optional) The ID of the Domain to scope to (Identity v3). If omitted, the OS_DOMAIN_ID environment variable is checked.

  • domain_name - (Optional) The Name of the Domain to scope to (Identity v3). If omitted, the following environment variables are checked (in this order): OS_DOMAIN_NAME.

  • default_domain - (Optional) The ID of the Domain to scope to if no other domain is specified (Identity v3). If omitted, the environment variable OS_DEFAULT_DOMAIN is checked or a default value of "default" will be used.

  • insecure - (Optional) Trust self-signed SSL certificates. If omitted, the OS_INSECURE environment variable is used.

  • cacert_file - (Optional) Specify a custom CA certificate when communicating over SSL. You can specify either a path to the file or the contents of the certificate. If omitted, the OS_CACERT environment variable is used.

  • cert - (Optional) Specify client certificate file for SSL client authentication. You can specify either a path to the file or the contents of the certificate. If omitted the OS_CERT environment variable is used.

  • key - (Optional) Specify client private key file for SSL client authentication. You can specify either a path to the file or the contents of the key. 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.

  • swauth - (Optional) Set to true to authenticate against Swauth, a Swift-native authentication system. If omitted, the OS_SWAUTH environment variable is used. You must also set username to the Swauth/Swift username such as username:project. Set the password to the Swauth/Swift key. Finally, set auth_url as the location of the Swift service. Note that this will only work when used with the OpenStack Object Storage resources.

  • use_octavia - (Optional) If set to true, API requests will go the Load Balancer service (Octavia) instead of the Networking service (Neutron).

» Additional Logging

This provider has the ability to log all HTTP requests and responses between Terraform and the OpenStack cloud which is useful for troubleshooting and debugging.

To enable these logs, set the OS_DEBUG environment variable to 1 along with the usual TF_LOG=DEBUG environment variable:

$ OS_DEBUG=1 TF_LOG=DEBUG terraform apply

If you submit these logs with a bug report, please ensure any sensitive information has been scrubbed first!

» 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.

You should be able to use any OpenStack environment to develop on as long as the above environment variables are set.

Most of Terraform's OpenStack support is done in a standardized Packstack all-in-one environment. You can find the scripts to build this environment here. The included main.tf file will need to be modified for your specific environment. Once it's up and running, you will have access to a standard, up-to-date OpenStack environment with the latest OpenStack services.

If you require access to deprecated services, such as Keystone v2 and LBaaS v1, you can use the "legacy" environment here.
