OTC Extensions

The OTC Extensions augment the OpenStack SDK of features and services provided by the Open Telekom Cloud. If installed as a Python package, they add several extra commands to the OpenStack Client CLI. Therefore the project interacts closely with the

• python-openstacksdk
• python-openstackclient

packages.

Installation

Installation Page

The OTC Extensions are hosted as the package otcextensions on PyPI and can be installed by pip as

There are several options to do that including but not limited to pip userland installation, system wide installation as well as installation from operating system packets or directly from source. Refer to the installation instructions in the projects documentation.

Configuration

Configuration Page

Acessing the Open Telekom Cloud APIs requires authentication and authorization. For both there are several options available:

• Configuration files (recommended): A file called clouds.yaml holds all necessary configuration parameters. The file can be placed either in the local directory, below the user home directory in .config/openstack or in the system-wide directory /etc/openstack. You may use a second file secure.yaml in the same directories to extra protect clear-text password credentials. For more details see the section configuration in the official documentation.

  Minimal sample clouds.yaml file:

  clouds:
    otc:
      profile: otc
      auth:
        username: '<USER_NAME>'
        password: '<PASSWORD>'
        project_name: '<eu-de_project>'
        # or project_id: '<123456_PROJECT_ID>'
        user_domain_name: 'OTC00000000001000000xxx'
        # or user_domain_id: '<123456_DOMAIN_ID>'
        auth_url: 'https://iam.eu-de.otc.t-systems.com:443/v3'
      interface: 'public'
      identity_api_version: 3 # !Important
      ak: '<AK_VALUE>' # AK/SK pair for access to OBS
      sk: '<SK_VALUE>'

  With this configuration you can start using the CLI with openstack --os-cloud otc *command* or by export OS_CLOUD=otc; openstack *command*.

• Environment variables: Authentication using username/password is often used:

  export OS_AUTH_URL=<url-to-openstack-identity>
  export OS_IDENTITY_API_VERSION=3
  export OS_PROJECT_NAME=<project-name>
  export OS_PROJECT_DOMAIN_NAME=<project-domain-name>
  export OS_USERNAME=<username>
  export OS_USER_DOMAIN_NAME=<user-domain-name>
  export OS_PASSWORD=<password>  # (optional)
  export S3_ACCESS_KEY_ID=<access_key>
  export S3_SECRET_ACCESS_KEY=<secret_access_key>
  

• Command-Line Options: The corresponding command-line options look very similar:

  --os-auth-url <url>
  --os-identity-api-version 3
  --os-project-name <project-name>
  --os-project-domain-name <project-domain-name>
  --os-username <username>
  --os-user-domain-name <user-domain-name>
  [--os-password <password>]
  
  If a password is not provided above (in plaintext), you will be
  interactively prompted to provide one securely.
  

• Existing Token: Authentication may also be performed using an already-acquired token and a URL pointing directly to the service API that presumably was acquired from the Service Catalog:

  export OS_TOKEN=<token>
  export OS_URL=<url-to-openstack-service>
  

• The corresponding command-line options look very similar:

  --os-token <token>
  --os-url <url-to-openstack-service>
  

In addition to that a regular clouds.yaml configuration file can be used
