Client

class barbicanclient.client.Client(session=None, *args, **kwargs)

Barbican client object used to interact with barbican service.

Parameters:
  • session – An instance of keystoneclient.session.Session that can be either authenticated, or not authenticated. When using a non-authenticated Session, you must provide some additional parameters. When no session is provided it will default to a non-authenticated Session.
  • endpoint – Barbican endpoint url. Required when a session is not given, or when using a non-authenticated session. When using an authenticated session, the client will attempt to get an endpoint from the session.
  • project_id – The project ID used for context in Barbican. Required when a session is not given, or when using a non-authenticated session. When using an authenticated session, the project ID will be provided by the authentication mechanism.
  • verify – When a session is not given, the client will create a non-authenticated session. This parameter is passed to the session that is created. If set to False, it allows barbicanclient to perform “insecure” TLS (https) requests. The server’s certificate will not be verified against any certificate authorities. WARNING: This option should be used with caution.
  • service_type – Used as an endpoint filter when using an authenticated keystone session. Defaults to ‘key-management’.
  • service_name – Used as an endpoint filter when using an authenticated keystone session.
  • interface – Used as an endpoint filter when using an authenticated keystone session. Defaults to ‘public’.
  • region_name – Used as an endpoint filter when using an authenticated keystone session.
