Description

There are three main ways of authenticating with Designate:

  1. The first one is by using the OS_CLOUD environment variable and a clouds.yaml file.
  2. The second one is using your username and password, via the OS_USERNAME, OS_PASSWORD and OS_PROJECT_NAME environment variables.
  3. The third one is by using an application credential, via the OS_APPLICATION_CREDENTIAL_* and OS_USER_ID environment variables.

For the username/password and application methods, the OS_AUTH_URL and OS_REGION_NAME environment variables are required.

For more information, you can read about the different methods of authentication with OpenStack in the Keystone’s documentation and the gophercloud documentation:
