Open Telekom Cloud Provider

The Open Telekom Cloud provider is used to interact with the many resources supported by OpenTelekomCloud. 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 OpenTelekomCloud Provider
provider "opentelekomcloud" {
  user_name   = var.user_name
  password    = var.password
  domain_name = var.domain_name
  tenant_name = var.tenant_name
  auth_url    = "https://iam.eu-de.otc.t-systems.com/v3"
}

# Create a web server
resource "opentelekomcloud_compute_instance_v2" "test-server" {
  # ...
}

Authentication

This provider offers 5 means for authentication.

  • User name + Password

  • AK/SK

  • Token

  • Federated

  • Assume Role

  • OpenStack configuration file

User name + Password

provider "opentelekomcloud" {
  user_name   = var.user_name
  password    = var.password
  domain_name = var.domain_name
  tenant_name = var.tenant_name
  auth_url    = "https://iam.eu-de.otc.t-systems.com/v3"
}

AKSK

provider "opentelekomcloud" {
  access_key  = var.access_key
  secret_key  = var.secret_key
  domain_name = var.domain_name
  tenant_name = var.tenant_name
  auth_url    = "https://iam.eu-de.otc.t-systems.com/v3"
}

Temporary AKSK

provider "opentelekomcloud" {
  access_key     = var.access_key
  secret_key     = var.secret_key
  security_token = var.security_token
  domain_name    = var.domain_name
  tenant_name    = var.tenant_name
  auth_url       = "https://iam.eu-de.otc.t-systems.com/v3"
}

Token

provider "opentelekomcloud" {
  token       = var.token
  domain_name = var.domain_name
  tenant_name = var.tenant_name
  auth_url    = "https://iam.eu-de.otc.t-systems.com/v3"
}

-> If token, AK/SK and password are set simultaneously, authentication will be done in the following order: Token, AK/SK, and Password.

Federated

provider "opentelekomcloud" {
  token          = var.token
  security_token = var.security_token
  access_key     = var.access_key
  secret_key     = var.secret_key
  domain_name    = var.domain_name
  tenant_name    = var.tenant_name
  auth_url       = "https://iam.eu-de.otc.t-systems.com/v3"
}

Assume Role

User name + Password

provider "opentelekomcloud" {
  agency_name        = var.agency_name
  agency_domain_name = var.agency_domain_name
  delegated_project  = var.delegated_project
  user_name          = var.user_name
  password           = var.password
  domain_name        = var.domain_name
  auth_url           = "https://iam.eu-de.otc.t-systems.com/v3"
}

User ID + Password + TOTP

provider "opentelekomcloud" {
  agency_name        = var.agency_name
  agency_domain_name = var.agency_domain_name
  delegated_project  = var.delegated_project
  user_id            = var.user_id
  password           = var.password
  domain_name        = var.domain_name
  auth_url           = "https://iam.eu-de.otc.t-systems.com/v3"
  passcode           = var.passcode
}

AK/SK

provider "opentelekomcloud" {
  agency_name        = var.agency_name
  agency_domain_name = var.agency_domain_name
  delegated_project  = var.delegated_project
  access_key         = var.access_key
  secret_key         = var.secret_key
  domain_name        = var.domain_name
  auth_url           = "https://iam.eu-de.otc.t-systems.com/v3"
}

Temporary AKSK

provider "opentelekomcloud" {
  agency_name        = var.agency_name
  agency_domain_name = var.agency_domain_name
  delegated_project  = var.delegated_project
  access_key         = var.access_key
  secret_key         = var.secret_key
  security_token     = var.security_token
  domain_name        = var.domain_name
  auth_url           = "https://iam.eu-de.otc.t-systems.com/v3"
}

Token

provider "opentelekomcloud" {
  agency_name        = var.agency_name
  agency_domain_name = var.agency_domain_name
  delegated_project  = var.delegated_project
  token              = var.token
  auth_url           = "https://iam.eu-de.otc.t-systems.com/v3"
}

token specified is not the normal token, but must have the authority of Agent Operator.

OpenStack configuration file

provider "opentelekomcloud" {
  cloud = var.cloud_name
}

cloud should be the name of cloud in clouds.yaml

See OpenStack configuration documentation for details.

Configuration Reference

The following arguments are supported:

  • access_key - (Optional) The access key of the OpenTelekomCloud cloud to use. If omitted, the OS_ACCESS_KEY environment variable is used.

  • secret_key - (Optional) The secret key of the OpenTelekomCloud cloud to use. If omitted, the OS_SECRET_KEY environment variable is used.

  • 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.

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

  • user_id - (Optional) The ID of the user to login with. Required when TOTP is used (passcode is not empty). If user_id is set, user_name is ignored.

  • 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.

  • region - (Optional) The name of the region to be used. Required for some resources (e.g. s3_bucket) in case no tenant name provided and no region is defined in the resource. If omitted, the OS_REGION or OS_REGION_NAME environment variables 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_AUTH_TOKEN or OS_TOKEN environment variable is used.

  • security_token - (Optional) Security token required to authenticate with temporary AK/SK.

  • passcode - (Optional) One-time password provided by your authentication app.

-> Please note that MFA requires user_id to be used. Setting user_name won't work.

  • 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_USER_DOMAIN_NAME, OS_PROJECT_DOMAIN_NAME, OS_DOMAIN_NAME, DEFAULT_DOMAIN.

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.

-> This will only work when used with the OpenTelekomCloud Object Storage resources.

  • agency_name - (Optional) if authorized by assume role, it must be set. The name of agency.

  • agency_domain_name - (Optional) if authorized by assume role, it must be set. The name of domain who created the agency (Identity v3).

Additional Logging

This provider has the ability to log all HTTP requests and responses between Terraform and the OpenTelekomCloud 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!

Creating an issue

Issues can be used to keep track of bugs, enhancements, or other requests. See the github help here

Testing and Development

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

  • 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 OpenTelekomCloud environment to develop on as long as the above environment variables are set.
