Message API configuration

The Message service has two APIs: the HTTP REST API for WSGI transport driver, and the Websocket API for Websocket transport driver. The Message service can use only one transport driver at the same time. See zaqar-drivers for driver options.

The functionality and behavior of the APIs are defined by API versions. For example, the Websocket API v2 acts the same as the HTTP REST API v2. For now there are v1, v1.1 and v2 versions of HTTP REST API and only v2 version of Websocket API.

Permission control options in each API version:

  • The v1 does not have any permission options.
  • The v1.1 has only admin_mode option which controls the global permission to access the pools and flavors functionality.
  • The v2 has only:
    • RBAC policy options: policy_default_rule, policy_dirs, policy_file which controls the permissions to access each type of functionality for different types of users. See ../policy-json-file.
    • secret_key option which defines a secret key to use for signing special URLs. These are called pre-signed URLs and give temporary permissions to outsiders of the system.
